Compress an image to 20KB
Some forms require very small images, like a 20KB signature or ID photo. Drop your image below and CompressEasy fits it under 20KB while keeping it as clear as possible, all locally in your browser.
Target is set to 20 KB. Drag in an image and we fit it under that size automatically.
How it works
- Drop your image into the upload area.
- CompressEasy searches for the best quality under 20KB.
- Download your 20KB image.
For signatures and ID photos
Exam and visa portals often require photos or signatures under 20KB. CompressEasy reaches that target automatically, saving you repeated re-exports.
Reaching very small sizes
At 20KB, resolution matters most. If your image will not fit, reduce its pixel dimensions first, then compress to the 20KB target with JPEG.
Local and free
Your image stays on your device. There is nothing to install and no upload.

Frequently asked questions
My photo will not get under 20KB. What can I do?
Lower the image resolution (pixel dimensions) and use JPEG. Smaller dimensions make very small file sizes achievable while staying legible.
Is JPEG the right format for 20KB?
Usually yes. JPEG offers the best size-to-compatibility balance for tiny photo targets.
Is it private?
Yes. Everything runs in your browser with no uploads.
