We hate online tools that upload your files.So we built ones that don't.

Every tool on this site runs entirely on your device. Nothing you edit, convert, or compress is ever sent anywhere — not to “generate a preview,” not to “check the file size,” not for any reason.

Works with wifi off

Here's what got under our skin: every “free” online tool wants your file first. You drop in a résumé, a scanned ID, a family photo, a contract — and it goes to a server you've never heard of, gets processed by code you can't see, and maybe gets deleted afterward. You just have to take their word for it.

So we stopped taking anyone's word for it. Every tool here runs in your browser — which means your file never leaves your computer in the first place. Not “we promise to delete it.” Never uploaded at all.

How it works

1
Drop your file in
Drag it onto the page, or click to browse. Nothing happens over the network — the file just loads into your browser’s memory.
2
We process it right there
Resize, compress, convert — it all runs in your tab. Turn your wifi off partway through and watch it keep working.
3
You download the result
The finished file saves straight from your browser to your device. It was never anywhere else in between.

More categories land as we build them. If a tool's missing, it means we haven't gotten to it yet — not that it's a paid feature.
