Compress an image to 20KB
Need a photo under 20 KB? Some forms — ID and exam uploads, older portals, signature fields — cap files near 20 kilobytes. Add your image and it's compressed to land at or under 20 KB while staying as clear as that size allows. It all runs in your browser, so your file is never uploaded.
Images are compressed to at or under your target, and never leave your device.

How it works
- Drag your photos in, or choose them from your device.
- The target is preset to 20 KB — change it any time.
- Download each compressed image once it's ready.
What to expect at 20 KB
20 KB is thumbnail territory. A head-and-shoulders photo around 400x400 lands here and still reads clearly, because a face is mostly smooth tone. A landscape or a busy street scene at the same size will show visible blocking in the detailed areas — there simply aren't enough bytes for that much texture. If the form allows it, crop tightly before compressing: fewer things in the frame is the cheapest quality win at this size.
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.

Questions
- How do I get an image under 20KB?
- Add your photo and the tool lowers quality and, if needed, dimensions just enough to land at or under 20 KB, then you download it. JPG and WebP reach tiny targets like 20 KB most reliably.
- Will a 20KB image still be usable?
- At 20 KB a picture is small, so it suits ID photos, signatures, and thumbnail uploads rather than large detailed images. The tool keeps as much sharpness as 20 KB allows.
- Is my image uploaded anywhere?
- No. Compression happens entirely on your device in the browser, so your photo never leaves your computer.
