What do I get back from Resize by Width?

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.

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.
