Compress to 20 KB

Add an image to enable compression.

Compress an image to 20KB free, right in your browser. A 20KB limit is one of the strictest you'll meet — it's the standard cap for photo and signature uploads on government portals, exam applications and visa forms, where a photo from any modern phone is hundreds of times too big.

This tool finds the best combination of JPEG quality and dimensions that fits under 20KB, so you get the clearest image the limit allows. Everything runs on your device — your photo or signature is never uploaded to a server, which matters when the image is your ID, your face or your handwriting. If the result looks too soft, crop the image to just the important area first and compress again.

Frequently asked questions

Why does my photo look softer at 20KB?
20KB is a very small budget — roughly 2% of a typical phone photo — so the tool has to lower the JPEG quality and usually shrink the dimensions too. It always picks the clearest version that fits. For the best result, crop away everything unnecessary before compressing, so the pixels that remain are the ones that matter.
Will this work for government and exam portal uploads?
Yes — that's exactly what a 20KB target is for. Portals that cap photo or signature uploads at 20KB accept standard JPG files, which is what this tool produces. Check your portal's exact requirements, since some also demand specific pixel dimensions.
Is my photo or signature uploaded anywhere?
No. Compression runs entirely in your browser using the Canvas API, so the image never leaves your device — important when the file is your ID photo or signature. The tool is free with no sign-up.
