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.

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.

Will I notice a quality difference?

Re-encoding always costs something, so start at the lighter setting and only push further if the size is still wrong. The before-and-after figures on the page are the honest way to decide.
