How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a Facebook Archive from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your HTML the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Open source, every line of conversion code is public.

Formats involved

About Facebook Archive and HTML

Facebook Archive, Facebook data export

Facebook's data export (Settings → Your Facebook Information → Download Your Information) lets users download an account's full history. Output is either an HTML browseable bundle or JSON. The JSON shape includes posts, photos, messages, ads-targeting categories, and friend relationships. Useful for migrating to other social platforms or maintaining a personal record.

How to open

HTML version is browser-openable as a static site. JSON requires conversion to CSV/HTML for casual browsing.

HTML, HyperText Markup Language

HTML is the markup language of the web, every browser displays HTML documents natively. Files contain text plus tags (<h1>, <p>, <a>, etc.) describing structure and links. Modern HTML5 also supports embedded media (audio/video) and complex semantic markup.

How to open

Every web browser. Any text editor for source. Modern editors (VS Code) syntax-highlight HTML.

FAQ

Common questions

Is this Facebook Archive → HTML converter really free?

Yes. No signup, no watermark, no daily file count limit. The entire engine is open source, you can read the conversion code on GitHub.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert Facebook Archive to HTML?

Personal record; account migration; data portability. Web pages; structured document interchange; readable archives. The most common reason to convert is compatibility, HTML works in places where Facebook Archive doesn't, or vice versa.

How do I open a Facebook Archive file in the first place?

HTML version is browser-openable as a static site. JSON requires conversion to CSV/HTML for casual browsing.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
