Where a 20 KB limit is common
- Signature uploads on FPSC, PPSC and many job portals
- Small passport-style photos on admission forms
- Thumbnail images
Tips for the best result at 20 KB
- Crop away empty background first – fewer pixels means more quality per KB.
- If text looks soft, set a max width (600–800 px) instead of letting quality drop.
- Need exact pixels as well as KB? Use the photo resizer or signature resizer.

Frequently asked questions
How do I compress an image to 20KB?
Choose your image above. The limit is already set to 20 KB; the tool finds the highest JPG quality that fits and shrinks the dimensions only if needed. Then press Download.
Will a 20KB image still be clear?
At 20 KB images should be small – around 150–300 pixels wide – which is what forms with this limit expect. Faces and signatures stay clear at that size.
Is my photo uploaded?
No. Compression runs in your browser, so the image stays on your phone or computer.
