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.
| ForgeMyFile | Typical online converter | |
|---|---|---|
| Files uploaded to a server | Never | Yes, every conversion |
| Files stored after conversion | Impossible — nothing to store | Often retained 1–24 hours |
| Account / email required | No | Often, especially for larger files |
| File size limits | Your device's RAM | Typically 5–100 MB free tier |
| Works offline (after first load) | Yes | No |
| Source of conversion engine | Open-source libraries, view-source-able | Proprietary server-side, opaque |
| Speed | Limited by your CPU | Limited by upload speed + queue |
| Page itself shows ads | Yes, plainly labeled | Yes, often disguised |
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 base64 ↔ file

Frequently asked questions
Will my file or data be uploaded?
No. Encoding/decoding uses the browser's FileReader and atob.
What about data: URI prefix?
Decode handles strings with or without the prefix.
Encoding format?
Standard base64. Not URL-safe — let us know if you need that variant.
Is there a size limit?
Browser memory only. Multi-megabyte files work; very large files may slow encoding visibly.
