Your files never leave this device.
Most "free online tools" upload your file to their server, process it there, and keep logs. Momo Tools is built the opposite way: every tool runs inside your browser using local processing (WebAssembly, Canvas, Web Crypto). There is no upload endpoint to send your data to.
| Momo Tools | Typical online tool | |
|---|---|---|
| Where files are processed | On your device | Uploaded to their servers |
| Account required | Never | Often, for "free" limits |
| Works offline | Yes — try airplane mode | No |
| File size limits | Your device's memory | 5–50 MB, pay to raise |
| Watermarks on output | Never | Common on free tiers |
| What we can see | Nothing — data never reaches us | Your files & metadata |
Verify it yourself in 20 seconds
- Open any tool — for example the Image Compressor.
- Turn on airplane mode (or unplug your network).
- Compress an image. It works — because nothing is being uploaded anywhere.
You can also watch the Network tab in your browser's DevTools: no file requests leave the page.
FAQ
If nothing is uploaded, how do the tools work?
Modern browsers are powerful. Image compression uses the Canvas API, PDFs are processed with WebAssembly libraries, hashes use the built-in Web Crypto API. Your CPU does the work — which is also why the tools feel instant.
Does that apply to every tool on this site?
Yes. Files, text, passwords and IDs are all processed locally. The only network requests the site makes are for the page itself, and (for the currency converter) a cached exchange-rate table that contains no personal data.
How does the site make money then?
Through clearly-labelled ads and affiliate recommendations on the page — never by selling data we don't have.
