How do I get an image under 30KB?

Add your photo and the tool lowers quality first, then dimensions if that's the only way to reach 30 KB. Save it as JPG or WebP — those two hit tight targets far more reliably than PNG.

Should I use 20KB or 30KB?

Use whichever your form actually asks for. The extra 10 KB is worth having if you're allowed it — faces and text come out noticeably cleaner at 30 KB than at 20 KB.

Is my image uploaded anywhere?

No. Compression happens entirely on your device in the browser, so your photo never leaves your computer.

Compress an image to 30KB

30 KB is a strict cap, but a little kinder than 20 KB — it turns up on exam portals, ID uploads, and older systems that reject anything heavier. Add your image and it's compressed to land at or under 30 KB while holding on to as much clarity as that size allows. It runs in your browser, so your file is never uploaded.

What to expect at 30 KB

30 KB gives a little more room than 20 KB, and it is the usual ceiling for forum avatars and small profile pictures. Expect a clean result up to roughly 500x500 for a portrait or a simple graphic. Photos with fine detail — foliage, crowds, textured fabric — will soften noticeably, because detail is exactly what costs bytes.

Which format to choose

For photographs, JPG is the safe choice, and WebP is usually 25–35% smaller again at the same visible quality — worth picking if whatever you are uploading to accepts it, as a few older forms still don't. For screenshots, charts, logos and anything containing text, PNG keeps edges crisp where JPG smears them into a grey haze; the file will be larger, so give it a more generous target. If your image needs a transparent background, use PNG or WebP — JPG has no transparency and will flatten it onto white.
