Is there a file size limit?

A single file may be up to 100 MB, and a batch up to 50 files. Those are guardrails rather than a paid tier — the work happens on your machine, so an enormous document is limited by your own memory before it is limited by us.

Does my file get uploaded?

No. The page reads the file through the browser's own file API and processes it in the tab. Closing the tab discards the working copy, which is why there is no storage to clear and no retention policy to read.

Will it work on a phone?

Yes. The layout adapts to a small screen and the processing runs in the mobile browser, so a photo or a downloaded document can be handled on the device it arrived on.

Because the expensive part — the server farm — does not exist. Processing runs on your device, so the site can stay free without a signup wall in front of it or an upsell in the middle of a job.
