Why it's different

How it works is the whole point.

Drop it in, take it out

No accounts. No emails. No tutorial. Open a tool, choose your file, download the result.

Your file never moves

Everything processes inside your browser tab. We're not watching — we technically can't.

Free. Not the fake kind.

Every tool. Every feature. No trial, no paywall, no "premium" gate hiding things you need.

Run it as much as you want

Back-to-back, all day. We're not counting your usage or throttling anything.

Multiple files, no problem

Stack files together, process them in one shot. Merge, split, batch — it all works.

Fast because it's local

No waiting for a server. Your CPU does the work — which means it's done the moment it's done.
