Compress Image to 20KB
Shrink a photo or signature to under 20KB — for the strictest upload limits on exam and KYC forms.
How to use it
- Click Choose image (or drag and drop your photo onto the button).
- The tool processes your image right in your browser — nothing is uploaded anywhere.
- Click Download to save the result.
For signatures and strict portals
Some portals — certain bank KYC uploads and older government sites — demand photos under 20KB, which phone cameras never produce directly. Signatures compress especially well since they are mostly white space.
Frequently asked questions
How do I compress an image to 20KB?
Choose your image and the tool squeezes it below 20KB by lowering quality and, if needed, dimensions.
Will a 20KB image still look okay?
For small uses like signatures and passport photos on forms, yes. Very detailed photos may look soft — that is the price of 20KB.
Is my photo uploaded anywhere?
No — all processing happens in your browser. Nothing leaves your device.
Which images work best?
JPG photos compress best. Simple graphics and signatures shrink to 20KB very easily.
