Markdown to HTML Converter

Turn Markdown files into HTML in a couple of clicks. Markdown is a readable plain-text formatting used across developer tools; HTML is the markup language of the web. Content is preserved and the layout is rebuilt for the target format.

How to use it

  1. 1

    Add your Markdown files

    Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.

  2. 2

    Adjust the settings if you want to

    There is nothing to configure — the layout is rebuilt for HTML automatically. That rebuild is where the differences show up, so check headings, tables and page breaks in the result.

  3. 3

    Convert and download

    Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your Markdown file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your Markdown file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

A Word file is usually a draft — which means it carries the things that were not meant to be final, and often tracked changes and comments nobody removed. It matters more than it sounds, because of what documents usually are:

Employment contracts

salary, notice periods, restraint clauses

A CV or résumé

home address, phone number, date of birth, full work history

Legal letters and NDAs

privileged material, and named third parties

Tenancy and loan agreements

identity details plus your financial position

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

Markdown and HTML explained

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

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

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

Markdown vs HTML

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

Why convert Markdown to HTML?

People make this switch when they run into the limits of Markdown: precise layout is required. HTML is the better fit when publishing on the web or generating documents programmatically.

Markdown limitations that prompt the switch
Dialects differ, so tables and footnotes are inconsistent. Limited layout control. Not a final deliverable format.
What you give up
Layout depends on the renderer and available fonts. Not a fixed-layout format.

What is preserved when converting Markdown to HTML?

The content survives; the layout is rebuilt. Text and the order it is read in carry across, but HTML lays the page out again rather than reproducing Markdown's exact positioning, so line breaks, page breaks and spacing will differ. Anything that depends on precise placement is worth checking in the result.

Markdown to HTML Converter — questions

How do I convert Markdown to HTML?

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

Is it safe to convert Markdown files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your Markdown file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential Markdown files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

What is preserved when converting to HTML?

Text, structure and images carry over faithfully. Exact page layout does not, because HTML lays content out differently from Markdown. Check headings, tables and page breaks in the result.

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. Pick the file through your phone's file picker — Files on iOS, or Downloads on Android — including files stored in iCloud or Google Drive.
