Can I process several files at once?

Yes, up to 50 files in a batch, each no larger than 100 MB. Results come back together instead of one save dialog per file.

Where does the processing actually happen?

In this tab. The file is read locally, converted or edited locally, and handed back as a download — no copy is sent to a server, so there is nothing for anyone to breach or keep.

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.

Is this free, or free until it asks for a card?

Free, with no upsell behind it: no account to create and no file-count quota that appears halfway through a job.
