File tools that never leave your device.
I build converters, compressors and utilities that run entirely in your browser. No uploads, no size limits, no sign-ups, and every one of them is free.
it really works like this. I built it myself.
The toolbox
Search by name, or by the file you're holding.
Three steps. That's it.
Complex file jobs, turned into one-click actions.
Drop your files
Pick one file or a hundred. Nothing is sent anywhere. Your browser simply reads them from your device.
Tweak if you want
The defaults work for most jobs. Advanced users get every setting they'd expect to personalise the result.
Download the result
Click convert, then save. Even gigabytes of files finish in seconds because there's no upload to wait for.
// under the hood
Built to be fast, not fancy.
Every conversion engine runs in your browser and uses the Worker API, which keeps memory in check and the page responsive while heavy jobs run in the background.
Because the work happens on your own hardware, the tools are tuned to make full use of modern phone processors as well as desktop ones. Big batches don't need a big machine.
No servers in the middle also means no queue, no file size limit, and nothing to breach. You can convert a 100 KB image or a 1 GB PDF the same way.
// about
One person. Every tool.
I got tired of converters that make you upload private files and wait. So I built the ones I wanted to use.
I'm Vivek, a solo developer. I design, write and maintain every tool on this site myself, which is why each one stays small, focused and quick.
If you need something that doesn't exist yet, a private converter for your team or a custom utility, that's exactly the kind of thing I like building.
psst… no agency, no team, no template. Just me.

I build private, fast, browser-based apps for other people too. Tell me what you need.
