How do I convert HTML to Markdown?

Add your HTML file to the upload area above, then press Convert. The Markdown file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to Markdown reduce quality?

Nothing is re-encoded — the content is taken out of the HTML container as-is, so its quality is unchanged.

How large a file can I convert?

Up to 100 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

HTML and Markdown explained

HTML is the markup language of the web, describing document structure — headings, paragraphs, lists, links — which browsers then render.

Markdown is plain text with lightweight conventions — hashes for headings, asterisks for emphasis — that stays readable as written while converting cleanly to HTML.

Where HTML files come from: Web pages, email templates and exports from documentation tools.
Where Markdown is used: READMEs, documentation sites, notes apps and static blogs.

HTML vs Markdown

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

HTML compared with Markdown
Property	Source	Target
Compression	None	None
Introduced	1993	2004
Browser support	Every browser.	GitHub, Notion, Obsidian and most modern editors.

HTML is stronger at: Renders in every browser. Semantic structure aids accessibility and search engines. Styleable with CSS.
Markdown is stronger at: Readable as plain text and as rendered output. Version-controls cleanly. Converts to almost anything.

Why convert HTML to Markdown?

People make this switch when they run into the limits of HTML: you need a self-contained, fixed-layout file to send someone. Markdown is the better fit when documentation, notes and anything living in Git.

HTML limitations that prompt the switch: Layout depends on the renderer and available fonts. Not a fixed-layout format. Requires separate assets for images.
What you give up: Dialects differ, so tables and footnotes are inconsistent. Limited layout control.

What is preserved when converting HTML to Markdown?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
