Add your HTML file
Drop one or more .html files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Converting .html to .md rewrites the document's markup while keeping its readable content intact. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Converting .html to .md rewrites the document's markup while keeping its readable content intact. An .html file contains HyperText Markup Language — the tag-based markup that gives structure to every page on the web. Open one in a browser and it renders as a document; open it in an editor and you see the source.
A .md file is a Markdown document: plain text with lightweight conventions — # for headings, ** for bold, - for lists — that convert cleanly to HTML. It stays readable as raw text, which was the entire point of the design. For this route the practical draw is legible both raw and rendered and ideal for version control — diffs read like prose edits — balanced against dialect fragmentation: tables, footnotes, and highlights differ per flavor, which is worth knowing before you commit a large batch.
The practical trigger for this conversion is usually a mismatch: with .html, a single .html file does not bundle its images and stylesheets unless they are inlined. Switching to .md buys you legible both raw and rendered, which is why it is the better fit for rEADME files and documentation in code repositories. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
| Aspect | HTML document (.html) | Markdown document (.md) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | an element tree of nested tags with attributes, parsed into a DOM by an error-tolerant algorithm the standard specifies precisely | inline HTML is legal Markdown, providing an escape hatch for anything the lightweight syntax lacks |
| Strongest at | web pages and web applications | rEADME files and documentation in code repositories |
| Weak spot | a single .html file does not bundle its images and stylesheets unless they are inlined | dialect fragmentation: tables, footnotes, and highlights differ per flavor |

Select .md in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MD is selectable, the route is real and validated.
Press Convert. Parsing and rewriting run in local JavaScript with sanitization, so scripts and trackers are stripped along the way.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid MD file. Outputs keep the original filename with the .md extension.
There is no visual quality to lose — html is text-oriented and md is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Yes — the .html file is processed inside your browser tab and never uploaded. Parsing and rewriting run in local JavaScript with sanitization, so scripts and trackers are stripped along the way. Close the tab and the file is gone from memory.
GitHub, GitLab, and most developer platforms render .md automatically, editors like VS Code preview it live, and every plain-text editor can modify it. Dedicated Markdown apps exist on all desktop and mobile platforms.
It depends on the content: inline HTML is legal Markdown, providing an escape hatch for anything the lightweight syntax lacks. Convert one representative file first and compare before batch-processing a large set.
In .html, metadata travels inside the markup itself: the title element, meta tags, and Open Graph properties used for link previews. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .html → .md → .html is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
