Add a photo, signature or scan and get it down to 20 KB or less. The size is already set for you.
This page shrinks a picture to 20 KB or less. The target is already set, so you only add your image and press the button. Everything happens in your browser, so the picture is not uploaded anywhere.
A 20 KB limit is common for signature scans, small stamp-style photos and the tight upload fields some application forms and portals still use. The tool tries to keep the highest quality that still fits, and reduces the pixel size only when the quality alone cannot get under 20 KB.
Add your JPG, PNG, WebP or AVIF image, check that the maximum size shows 20 KB, and press Process Images. The result appears below with its real size, and you can compare the preview with your original before you download it.
At 20 KB a photograph is small. Expect roughly a few hundred pixels across, which is fine for a signature or a thumbnail but not for printing.
A signature on a white background compresses far better than a photograph, so scan or photograph it on plain white paper first.
If the form you are filling needs an exact pixel size as well, run the picture through the Image Resizer first and then compress it here.
Add the photo to the tool above and press Process Images. The size limit is already set to 20 KB, and the tool lowers quality and, if needed, dimensions until the file fits.
That depends on the picture. At 20 KB a photograph is small. Expect roughly a few hundred pixels across, which is fine for a signature or a thumbnail but not for printing.
Yes. Change the number in the "Maximum output size" box, or use the other pages for 20, 50, 100 and 200 KB. The Image Compressor also lets you pick any size in KB or MB.
No. The compression runs in your browser on your own device, so your photo, signature or ID picture stays with you.
The tool stops at the best quality that is under the limit, so the result is usually just below 20 KB rather than exactly 20 KB.
