Which file types does Resize by Pixels accept?

The drop area takes JPG, JPEG, PNG and 9 more. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".

What do I get back from Resize by Pixels?

The result is JPG, JPEG, PNG, WEBP, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.

How big a file can I use?

Up to 100 MB per file and 50 files per batch. There is no server queue behind that limit; the practical ceiling is your browser's memory, so split unusually large documents into two runs.

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.
