Which file types does Bulk Image Resizer 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 Bulk Image Resizer?

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.

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.

Is it safe to use for a document with personal details in it?

That is the design goal: the document stays on your device, so a statement, a contract or an ID photo is never transmitted for processing. Nothing here needs an internet connection once the page has loaded, apart from engines that fetch their own model data.
