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.

Is this free, or free until it asks for a card?

Free, with no upsell behind it: no account to create and no file-count quota that appears halfway through a job.

Which file types does Instagram 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".
