Compress Image to 20KB
Make a photo smaller than 20KB for signature uploads, which exam and job application forms often limit to 10–20 KB. It keeps the highest quality that fits, lowering the quality first and the dimensions only if it has to.

About the formats
- JPEG image
- JPG (JPEG) is the most widely supported photo format. It uses lossy compression, so files are small and open everywhere, at the cost of some detail.
- PNG image
- PNG is a lossless image format with transparency support. It's ideal for screenshots, logos and graphics with sharp edges.
- WebP image
- WebP is Google's modern image format for the web. It supports lossy and lossless compression and transparency, and is usually smaller than JPG or PNG.
FAQ
Frequently asked questions
Will it always get under 20KB?
Almost always. It tries the best quality first and lowers it step by step until the image fits. If even the smallest version is bigger (for example a very long document), it tells you the smallest size it could reach.
My form says 20KB. Is "20KB" here the same?
Here 1 KB is 1,000 bytes, the stricter of the two meanings, so a file under 20KB here is also under 20KB on forms that count 1 KB as 1,024 bytes.
Are my files uploaded?
No. The conversion runs inside your browser using WebAssembly, so your files never leave your device. Nothing is sent to our servers.
