→Everything happens inside your browser tab using your own device. Your documents are never sent anywhere — there's no server to send them to.
Because your device does the work, we don't pay per task — so there are no daily caps, no "2 files a day," no sign-up walls. Use it all day.
No Docker, no desktop app, no extension. Open the page and go. The privacy of self-hosting, with the ease of a website.
The popular tools are great — but they upload your files and ration the free tier. Here's the trade-off, plainly.
