Free HTML and Markdown Editor
Write in Markdown or edit supplied HTML in one workspace. Watch the preview update as you work, convert supported content in either direction, and export the version your publisher or team needs.
From guest posts and blog articles to README files and educational guides, organize headings, lists, tables, links, images, and code without losing sight of the rendered result. Keep article-body output separate from a complete HTML document.

Format your article in one workspace
Write. Preview. Prepare your handoff.
Keep the original source, inspect conversion notes, and export the format your publisher needs. Preview images and link navigation are blocked; no external resource is fetched by this editor.
Limit: 60,000 characters. Oversized input is rejected, not silently truncated. Ctrl/Command+Enter converts; Escape exits expanded view.
Line 1 · Column 1Images are represented by alt-text placeholders. Link destinations remain in exports, but cannot be opened from this preview.
Formatted clipboard support depends on your browser and receiving editor. HTML downloads do not publish a WordPress draft.
Find and replace
Literal matching only; replacements can be undone.
Starter templates and file open
Replacing an existing source requires confirmation. Templates contain no automatic sales links.
MD, TXT or HTML only. Maximum 240,000 bytes and 60,000 characters. DOCX and PDF imports are not supported.
Optional browser draft
Off by default. Enabling this saves the source and editor settings on this device, not to a cloud account. Anyone using this browser profile may access it. Turning it off removes the stored draft.
Draft saving is off.
Heading outline
Review the headings retained in output. Select one to find its text in the original source.

No document has been converted yet.
Retain your original. No converter can preserve every layout, custom style, widget or publishing-system setting. This workspace does not check facts, remote URL status or search rankings.
Supported formatting and shortcuts
Headings, paragraphs, emphasis, nested lists, quotes, links, reference links and literal code are supported. Select GFM for tables, tasks, strikethrough and automatic links. Optional footnotes, math, diagrams and front matter are not enabled here.
Use Ctrl/Command+B for bold, I for italic, K for a link, Z for undo and Shift+Z for redo. Ctrl/Command+Enter converts. Undo is bounded to 100 edits or 6 million source characters in this session; download a backup before leaving.
HTML cleanup uses a restricted allowlist. Scripts, forms, frames, event handlers and copied presentation styles are not part of the article output. Documents exceeding 64 nesting levels or 15,000 structural nodes are rejected without changing your input. Review the conversion notes for specific removals.
Choose the mode that matches your source:
Markdown to safe HTML
Markdown textHTML generated from supported Markdown basics and your selected GFM options
Clean existing HTML
Existing HTMLFiltered HTML using the selected article-body or document profile
HTML to Markdown
Existing HTMLEditable Markdown with compatibility notes for unsupported formatting
Paste your content or open a Markdown, plain-text, or HTML file. Select text to format and compare the live preview with the generated source. On mobile, switch to editor-only or preview-only view when you need more room. Conversion and supported exports run in your browser.
Input note: The current content field accepts up to 60,000 characters. This is a character limit, so the amount of article text it holds depends on your content and markup.
How to use the HTML and Markdown Editor
1. Choose the correct input format
Select Markdown when your source uses symbols such as ##, **bold**, and [link text](https://example.com/). Select HTML when it already contains tags such as <p>, <h2>, and <a>.
Choosing the right mode matters. HTML pasted into Markdown mode is treated differently from HTML submitted for cleanup.
2. Add the structure your reader needs
Use the toolbar to apply H2–H6 headings, bold or italic emphasis, bulleted and numbered lists, blockquotes, inline code, and links. Select the words or lines you want to format first.
Begin body sections with H2 when the article title will be supplied separately. Use H3 for a subsection within an H2 section, then lower levels only where the structure needs them.
3. Review the live preview
Read the live preview as a reader would. Check heading levels, paragraph separation, nested lists, quotations, tables, code, and the words used for each link. Review any cleanup or compatibility notes before exporting.
Review the HTML source as well as the preview. A document can look reasonable while a destination, heading, or unsupported element has changed during conversion.
4. Copy or download the format you need
Copy the generated HTML, or download an HTML body fragment, Markdown, plain text, or a standalone HTML document. Keep the original draft so you can restore any structure the receiving publisher requires.
Send the article title, source notes, image permissions, and publisher instructions separately when they are not part of the supported body output. Image URLs and alt text can be retained in the exported document, but external images are blocked in the preview.
What you can format
The editor supports common article structure, with a selectable GFM mode for tables, task lists, strikethrough, and automatic links. Review the active dialect and your receiving platform’s requirements.
H2–H6 headings
Sections and subsections within an article body
Paragraphs
Clear breaks between ideas
Bold and italic
Intentional emphasis within your text
Bulleted lists
Related points, examples, or requirements

Blockquotes
Separating a quotation from your own prose
Links
Connecting descriptive anchor text to a supplied destination
Inline code
Showing a short command, tag, or code term as literal text

Fenced code blocks
Preserving whitespace and literal markup in examples
Horizontal rules
Separating a change of topic without decorative layout wrappers
Use Undo and Redo to review recent editor changes. Retain your source document or download a backup before leaving the page. Local saving is optional and is not a cloud document library.
Footnotes, math, diagrams, front matter, and platform-specific extensions are not part of this release. Complex HTML layouts, forms, embeds, and custom CSS may not have equivalent Markdown structures. Review compatibility notes instead of assuming an exact round trip.
Markdown to HTML: a practical article example
Markdown lets you write structure with ordinary text characters. Here is a small example using supported article formatting:
## How to prepare an article draft
Start with a **clear main point** and a short introduction.
- Keep each section focused.
- Give readers a useful example.
- Review every link before submission.
Read the [publisher instructions](https://example.com/guidelines/) before sending the draft.The output contains an H2 section heading, paragraphs, bold emphasis, a bulleted list, and a link. The publisher can then apply its own site styles.
The example destination is illustrative. Replace it with the actual publisher’s URL before using the text in an article.
Clean existing HTML before a publisher handoff
HTML copied from another editor can contain font styling, layout wrappers, classes, and elements that do not belong in a simple article body. Cleanup reduces that markup to the supported subset.
For example, supplied HTML might look like this:
<div class="copied-document">
<h2 style="font-family:Arial">Choosing useful article topics</h2>
<p class="document-paragraph">
Start with a <strong>specific reader question</strong>.
</p>
</div>The useful structure is the heading, paragraph, and emphasis. The original wrapper and presentation styles are unnecessary for a publisher that will style the article through its own theme.
Cleanup filters unsupported tags, event-handler attributes, and disallowed URL protocols. The change report identifies removed markup and URL attributes. Compare the final output with your original before sending it; HTML recovery or filtering can change structure.
Convert HTML to Markdown without rebuilding the draft
Paste supplied HTML and turn supported headings, paragraphs, lists, links, emphasis, quotes, images, and code into editable Markdown. Convert compatible tables to GFM syntax when that mode is selected.
Review compatibility notes before replacing the original. Custom CSS, forms, embedded widgets, page layouts, and advanced table styling do not have equivalent Markdown structures. The editor identifies supported losses so you can decide how to handle them.
Choose the cleanup profile for your handoff
Use the article-body profile for simple publisher content, or the document profile when your output needs the supported structure of a general document. A standalone HTML download is separate from a CMS body fragment.
Review the original and output alongside the cleanup report. It identifies removed tags, attributes, and URL attributes without enabling arbitrary scripts, forms, or embeds.
Prepare tables, images, and literal code
Insert a supported table or edit its Markdown source, then review headers, alignment, and cell content. Use GFM mode when the receiving platform accepts tables and task lists.
Add an approved image URL with meaningful alt text. External images are blocked in the preview; confirm image permissions and the final destination separately. Image export does not upload, store, or verify the asset.
Use fenced code blocks for examples that need preserved spacing. Code stays literal, so HTML inside an example remains an example rather than active markup. This release does not apply language-based syntax highlighting.
Keep long drafts organized
Review the heading outline to navigate your draft and check its hierarchy. Use the available formatting shortcuts and literal find-and-replace controls to make repeated edits efficiently.
Start from a supplied article, educational-guide, or README/documentation template. Adapt the structure to your reader and remove sections that do not help. Templates are starting points, not a publication approval.
Choose the right file for the next step
Open one Markdown, plain-text, or HTML file, continue editing, and keep the original for comparison. File and input limits are shown by the editor; conversion is not a layout-perfect document importer.
Copy HTML source for a CMS, save Markdown for future editing, download readable plain text, or export a standalone HTML document for a complete file. The standalone file retains the no-external-image resource policy; approved image URLs remain in the source. Review the exported result before sharing it.
PDF, DOCX, batch conversion, rich document imports, and cloud publishing are not included in this release.
Work locally and choose whether to save
Core editing, conversion, preview, and the supported exports run in your browser. Leave local saving off for a temporary session, or enable it to restore your draft in the same browser.
Local storage is not a cloud backup. Download your draft before clearing browser data, using another browser, or changing devices. The editor does not import remote URLs or load external images in its preview.
Prepare HTML for WordPress and other publishers
Ask the receiving site which format it accepts. Some publishers want an HTML body fragment; others prefer a document or plain text that their editor will rebuild.
For a typical WordPress article handoff:
- Supply the article title separately from the body.
- Begin the body with your introduction and meaningful H2 sections.
- Provide the approved destination and anchor text for each link.
- Send images with alt-text, caption, source, and permission notes.
- Review a draft preview in the receiving CMS before publication.
The editor does not log in to WordPress, create a WordPress draft, or publish your article. Copying an HTML fragment gives you content to transfer into the publisher’s own workflow. The site’s editor, theme, permissions, and formatting policy can change how it appears.
Body-heading conventions help keep the handoff clear; they are not a promise of better Google rankings. Follow a logical hierarchy and the publisher’s requirements.
Review the writing before formatting the final version
Formatting is most useful after the article’s substance is ready. A polished preview cannot establish whether a claim is accurate or a source supports it.
Check the requested length and repeated phrases with the Word Counter and Keyword Density Checker. Phrase frequency describes your text; it does not provide an ideal density for ranking.
Use the Readability Score Calculator to estimate reading difficulty and identify writing that deserves closer review. A readability score does not verify the facts or usefulness of an article.
If the submission needs APA or MLA references, the Citation Generator can format the bibliographic details you supply. Review the source information yourself; formatting a reference does not validate it.
For a link list to accompany your submission, the URL, Link and Domain Extractor can extract URLs and HTML link details from supplied text or markup. It does not fetch the destinations or check their status.
Check the details that formatting cannot decide
Before sending a guest post or article, review:
- The argument: Each section should answer a useful reader question.
- The evidence: Claims, quotations, and statistics need appropriate sources.
- The links: Anchor text should describe the destination, and the final URL should be intentional.
- The images: Confirm permissions and provide useful alternative text.
- The publisher requirements: Match the accepted format, tone, length, and heading structure.
Our editorial standards explain the expectations for an article handoff. Keep these requirements beside the draft while you review it.
Frequently asked questions
Is this HTML and Markdown Editor free?
Yes. The supported editing, Markdown/HTML conversion, cleanup, and local export controls are free. Writing and placement services are separate.
What is the difference between Markdown and HTML?
Markdown uses lightweight text markers for structure, such as ## Section and **bold**. HTML uses elements such as <h2> and <strong>. This editor converts supported content between them or cleans HTML you already have.
Which Markdown features does the editor support?
Use CommonMark-compatible basics or enable GFM tables, task lists, strikethrough, and automatic links. These are separate from extensions such as footnotes, math, or diagrams, which are not included. Preview your specific document before export.
Can I convert HTML to Markdown?
Yes. Choose HTML to Markdown and review the supported result. Clean existing HTML remains a separate mode that returns filtered HTML. Compatibility notes identify formatting that does not have an equivalent Markdown representation.
Does the preview update as I type?
Yes. The live preview updates after source edits. Compare rendered and source views, and check the current output before copying or downloading. On smaller screens, use editor-only or preview-only view.
Why are the heading controls H2–H6?
The article title is usually entered separately in the receiving CMS. H2–H6 controls help organize the body beneath that title. Check the actual page template and publisher requirements when choosing heading levels.
Can I paste from Word or Google Docs?
You can paste text into the content field or open a supported Markdown, plain-text, or HTML file. Rich document formatting is not reliably carried into a plain textarea. Rebuild the structure you need and review the output. DOCX and PDF import are not included.
Why did formatting change during conversion?
Supported tables, image URLs, and literal code blocks can be retained, but complex layout, custom styling, embeds, and unsupported elements may be removed or simplified. Review the change report and keep your original. External images are blocked in the preview even when their URLs remain in exported output.
Will my links stay exactly the same?
Compare final link destinations with your approved URLs. Disallowed schemes and unsupported attributes are reported during cleanup. Relative paths depend on the receiving site, and a local preview does not check whether a remote destination exists. Prefer complete destinations for a publisher handoff.
Is conversion performed locally in my browser?
Core editing, conversion, preview, and the listed exports run in your browser. External images and document navigation are blocked in the preview. Loading the website still uses network resources; browser-local conversion is not a promise that the whole site works offline.
Does the editor save my article or create a WordPress draft?
It does not create a WordPress draft or publish an article. Local saving is off until you enable it, and a saved draft belongs to the same browser, not a shared cloud workspace. Download a backup before clearing browser data or changing devices.
Does clean HTML make an article SEO-ready?
Clear structure can make a draft easier to read and publish. Search performance also depends on the usefulness of the content, site accessibility, relevance, and many other factors. This editor does not check rankings, research sources, verify facts, or approve an article for publication.
Need help preparing the article itself?
If the draft still needs writing or editorial work, explore our guest post content writing service. Provide the topic, intended audience, publisher requirements, source expectations, and final format so the brief is clear before work begins.
