How it works

Most online converters send your file to their server, process it there and send it back. OptiPress skips the round trip.

  1. 01

    You choose a file

    Your browser reads it into memory, the same way it would preview a photo you attach to an email.

  2. 02

    The tool runs on your device

    The code was downloaded with the page. It does the work with your device's processor, in a background thread.

  3. 03

    You save the result

    The finished file goes straight to your downloads. Close the tab and the copies in memory are gone.

Check it yourself: open your browser's developer tools, go to the Network tab and run any tool. You'll see the page's own scripts and ads load, but no request that carries your file.

Questions

Something else? Contact us.

Do you upload or keep my files?

No. Each tool reads your file in the browser and processes it there. Nothing is sent to our servers, so there's nothing for us to store.

How do you make money?

Through ads shown by Google AdSense. That keeps the tools free, with no sign-up, limits or watermarks.

Does it work on my phone?

Yes. The tools run in any modern browser on Android, iOS, Windows, macOS and Linux. Large batches are faster on a computer.

Is there a file size limit?

There's no fixed limit, since the work happens on your device. Very large files depend on how much memory your browser can use.
