Compress JPG to 20 KB
Get a JPG at about 20 KB — handy for signatures and thumbnail photos on forms.
This page opens the JPG compressor pre-aimed at 20 KB. Many exam and bank forms cap signatures or small photos near 20 KB. Drop your photo and the tool searches the quality ladder for the best-looking result that still fits 20 KB; if the photo is too large to reach that at full resolution, it scales the longest edge down and tells you the exact size it achieved.
A small target like this means some loss of fine detail is expected — that's the trade-off for a tiny file. If your form allows a larger limit, a higher target will look better. Change the number any time; files are processed privately and deleted right after.
Frequently asked questions
Can any photo reach 20 KB?
Most can, because the tool will downscale the dimensions if adjusting quality alone isn't enough. Very large or highly detailed photos may need noticeable downscaling to hit 20 KB. The result always shows the size actually reached.
The output came out a little under the target — why?
Quality steps are discrete, so the tool picks the best quality whose size is at or just under 20 KB rather than going over. That keeps you safely within an upload limit.
My form needs exact pixel dimensions too. Can you do that?
Set a maximum width/height under Advanced options, or use the dedicated reduce image size tool for precise dimensions alongside the KB target.
Is it safe and private?
Your file is uploaded over HTTPS, processed on our server, and the upload is removed right after. The generated result is cleaned up automatically by a periodic job. We never share your files and no account is needed. See our Privacy Policy.
