Why can I put AVIF in but not get AVIF out?

Every current browser can decode AVIF, and none of them can encode it. Offering AVIF as an output would mean silently handing back a PNG with the wrong extension, so it is an input format only.

Will converting a PNG to JPG lose quality?

Once, yes — JPEG is lossy, so the re-encode costs a little detail. Transparency is lost as well: JPEG has no alpha channel, so transparent areas are filled with white before encoding.

Which format should I pick?

WebP for anything going on the web — the same quality in a noticeably smaller file, supported by every browser since 2020. JPEG for photos headed into older software. PNG for screenshots, logos and anything with sharp edges or transparency.

Is there a daily limit or a file-size cap?

Neither. Nothing is queued on a server, because the conversion runs on your own device — the only ceiling is how much memory your browser will give the page.

Browsers can read AVIF but none of them can write it, so AVIF is available as an input only. There is no point offering an output that would not work.

Coming from CloudConvert or Convertio?

They handle hundreds of formats, and for the rare ones they are the better choice. For JPG, PNG and WebP they upload your file and cap how many you can do in a day. This page converts on your own device — instantly, as many as you like.
