- 1
Drop your file in
Drag it anywhere on the page, or click to browse. The file is opened by the page itself, not sent anywhere.
- 2
It converts on your device
Your browser does the work using your own processor. A 40MB file takes the same time as a 40KB one, because nothing is travelling.
- 3
Save the result
The finished file lands in your downloads folder. Close the tab and every trace of it is gone.
Why this is different
Most free converters are a server with a web page in front of it. This is not that.
- × Your file is uploaded to a company's server
- × It is stored there for hours or days
- × Free tier caps the file size and daily use
- × You wait for the upload, then the download
- × Sign up, or the result gets a watermark
- × Useless without an internet connection
- ✓ The file never leaves your device
- ✓ Nothing is stored, because nothing arrives
- ✓ No size cap and no daily limit
- ✓ No transfer at all, so no waiting
- ✓ No account, no watermark, no upsell
- ✓ Works with the wifi switched off
You can check this yourself. Open any tool, turn off your internet, then convert a file. It still works — which is only possible if nothing was being sent.
Questions
Is it actually free?
Yes, with no catch. Conversions run on your device, so there are no server costs to recover — which is exactly why there is no paid tier, no daily cap and no watermark.
How big a file can I convert?
There is no fixed limit. The real ceiling is your device's memory. Files over about 80MB will show a warning, since they can be slow on older hardware.
Does it work on a phone?
Yes, on both iPhone and Android. Everything is built for touch, and you can add the site to your home screen to use it like an app.
Can I use it for client or confidential work?
Yes. There are no restrictions on commercial use, and since files never leave your device, confidential material stays that way.
