Get JPG, PNG or WEBP images under 20 KB for signatures, thumbnails and the strictest exam and job application forms, many at once.
How to compress an image
1
Select or drop up to 30 JPG, PNG, SVG, GIF or WEBP images.
2
Keep Recommended, or choose Smallest that looks the same for JPG and WEBP files.
3
Click Compress, then download each image or all of them in a ZIP.
Make an image 20 KB or smaller
20 KB is one of the tightest limits you will meet, usually for a scanned signature or a small photo on an exam or job application form. Set the size to 20 KB, add your images and each one is saved as a JPG just under it, at the highest quality that fits.
A large phone photo can't fit into 20 KB at full size, so it is also made smaller, step by step, until it does. A signature or a passport-style photo still looks clear at that size, because it only needs a few hundred pixels on each side.
Frequently asked questions
To fit 20 KB, a big photo has to lose pixels as well as some detail. The tool first lowers the JPG quality, and only when that isn't enough does it shrink the image. A form preview rarely shows more than a few hundred pixels anyway.
Files are kept under 20,000 bytes, which is below both readings. So the file passes whether the form counts a kilobyte as 1,000 or 1,024 bytes.
Yes. Crop the signature first if it has a lot of empty paper around it, then compress it to 20 KB here. Dark ink on white paper compresses well and stays sharp.
JPG and WEBP compression is lossy, but Recommended keeps a balance that suits most photos, and Smallest that looks the same checks each result against the original. PNG and SVG compression is lossless, so nothing visible changes in those files.
Up to 30 images or 200 MB per task. Add them all, click Compress once, and download the results one by one or together in a single ZIP file.
Some files are already well optimized. When the compressed version would be the same size or bigger, you get your original file back unchanged, and it is marked as already optimized.
No. Compression runs inside your browser on your own device. Your images are not uploaded or stored anywhere, which also means a large batch never waits for an upload to finish.
Recommended is fast and works well for most images. Choose Smallest that looks the same when file size matters most. It is slower, and a very detailed photo can sometimes come out larger than with Recommended.
