About Compress image to 20KB
Many government, exam and job portals ask for a photo or signature smaller than 20KB. A normal phone photo is often 2–5 MB, a hundred times too large. This tool shrinks your image to under 20KB automatically, adjusting quality and, only if needed, dimensions, so it is accepted on the first try.
For signatures and passport-size photos, 20KB is plenty: the tool keeps faces and handwriting clear while meeting the limit.
Hits the exact size
Quality is tuned automatically until the file lands just under 20KB — no trial and error.
Best possible quality
The tool keeps the original dimensions whenever it can, and only scales down if it must.

Frequently asked questions
How do I compress a photo to 20KB?
Select your photo, make sure the target size is 20KB and press “Compress to 20KB”. Your new image will be just under 20KB.
Can I compress a signature to 20KB?
Yes. Scanned or photographed signatures compress very well and stay sharp under 20KB.
Why is my image smaller in pixels after compressing?
If a large photo cannot fit in 20KB even at low quality, the tool also scales it down. Forms that need 20KB usually expect a small photo anyway.
Is it free to compress an image to 20KB?
Yes, completely free, with no limits, no sign-up and no watermark.
Are my photos uploaded?
No. Compression happens inside your browser, so your photos never leave your device.
