Compress Image to 20KB
Compress a JPG, PNG or WebP photo to under 20KB in your browser. Free, no sign-up, nothing uploaded.
How it works
20KB is a common limit for signature and small photo fields on older exam and government portals. Plain backgrounds compress far better than busy ones, so a signature on white paper or a face against a wall will keep its detail, while a crowded scene will turn soft.
- Choose your photo.
- Wait a moment while it is fitted to the limit.
- Download the JPG and upload it to your form.
Common questions
Will my photo look blurry at 20KB?
Slightly softer, yes. Photos with a plain background hold up well. Busy photos may look blocky, so retake them against a plain wall if the result is poor.
Does this work on PDFs?
No. This tool handles images (JPG, PNG and WebP). It does not compress PDF files.
Will the file be exactly 20KB?
It lands at or just under 20KB. The tool picks the best quality that still fits.
