ForgeMyFile vs typical online converters

A side-by-side. We're not picking on a specific competitor — these are the patterns common across the category.

Privacy, in plain language

We're going to be specific instead of saying things like "100% anonymous." That phrase is a lie on any page that loads ads — and we load ads. Here's what's actually true.

What runs entirely on your device

  • Reading your file from disk into the browser
  • The conversion itself — every one of the 13 tools
  • Saving the converted file to your downloads folder
  • The "preview" of converted text, JSON, or HTML

What does not run on your device

  • Ad scripts (when enabled by the operator) and their analytics
  • Page-view analytics, when enabled
  • The first-load fetch of Google Fonts CSS (libraries themselves are self-hosted)
  • After first load, the page works fully offline; ads do not

What we (the site operators) literally cannot see

  • Your file names
  • The contents of any file you convert
  • Which converter you used, or how often
  • Your conversion history

What ad networks may see

  • Your IP address and approximate location
  • Your user agent (browser + OS string)
  • The page you visited (URL)
  • Standard ad-serving cookies, where allowed by your browser

If you want to neutralize the ad networks too, run an ad blocker. The conversion tools themselves work either way — the privacy we offer for your files is independent of whether you block our ads.

How to use docx → html

  1. Drop a .docxWord, Google Docs export, LibreOffice all work.

Frequently asked questions

What about images inside the DOCX?

Embedded as base64 data: URLs in the HTML, so the file is self-contained.

Is the document uploaded?

No, mammoth.js parses the DOCX zip in your browser.

Tables, footnotes, comments?

Tables yes. Footnotes flatten. Comments are dropped.

Can I customize the HTML output?

The default style map covers most cases. For deep customization, run mammoth manually.
