What fits in 20 KB
A full photo usually comes out around 400 px on its long edge at this size, which suits a small ID photo. A signature on white paper keeps much more detail, because a plain background costs almost nothing.
Crop to your face or signature first. Every bit of background you remove leaves more of the 20 KB for the part that matters.
How to compress an image to 20 KB
- Choose or drop your image. Target size is already set to 20.
- Press Compress. It finds the highest quality that fits, and reduces the width and height only if it has to.
- Check the new size and the preview, then download the JPG.
FAQ
My form says 10 to 20 KB. Will this work?
Yes. The result lands just under 20 KB, which is inside that range. The size shows next to the file so you can check it before you upload.
My form says 20 to 50 KB. Should I use this page?
No. A file just under 20 KB falls below that minimum. Set the target to 50 instead, so the result lands near the top of the range.
Why does my photo have fewer pixels now?
JPEG quality can only drop so far before faces turn blocky. Past that point the tool reduces the width and height instead. Cropping first keeps more of the pixels that matter.
Is my image uploaded?
No. The whole search runs in this tab, using your browser's canvas.
Is 1 KB 1,000 or 1,024 bytes here?
The tool counts 1 KB as 1,000 bytes, so 20 KB means 20,000 bytes. That also passes a form that counts 1,024.
