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.

Because the expensive part — the server farm — does not exist. Processing runs on your device, so the site can stay free without a signup wall in front of it or an upsell in the middle of a job.

Which file types does App Icon 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 App Icon Resizer?

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