Compress an image to 20 KB

20 KB is a very small file — ideal for signatures, thumbnails and forms with a strict 20 KB limit. Drop a JPG or PNG and it's squeezed under 20 KB — for exam forms, passport and ID uploads. The picture stays as sharp as the limit allows.

How to compress an image to 20 KB

Drop your image above and download — the tool keeps your original dimensions and lowers the JPEG quality by binary search until the file fits just under 20 KB, so it stays as clear as possible. Everything happens on your device; nothing is uploaded. At 20 KB you get a clean signature or a small photo. If a portal also sets a minimum (e.g. 10 KB), keep the image reasonably sharp so it doesn't fall below it.

FAQ

How do I compress an image to 20 KB?

Drop your image above; the tool lowers the JPEG quality just enough to bring it under 20 KB while keeping it sharp, then you download. If it can't reach 20 KB at full size, use the resize tool to reduce the dimensions first.

Will it reduce the image dimensions?

No — it keeps your original width and height and only reduces the file size. To change dimensions too, use the resize tool.

Is my image uploaded anywhere?

No. Compression runs entirely in your browser; your image never leaves your device.
