Compress Image to 20 KB
Compress a JPG or PNG photo to under 20 KB for strict photo and signature fields on government exam and visa forms (SSC, UPSC, and similar). Free and private — the image is resized and re-compressed in your browser, never uploaded.
To compress an image to 20 KB, this tool automatically searches for the highest JPEG quality that lands under 20 KB, stepping the dimensions down if needed. Drop your photo and it targets 20 KB for you. If a file genuinely can't reach 20 KB while staying legible, it delivers the smallest possible version and tells you the exact size. Everything runs in your browser.
🔒 Compression runs locally — your image is never uploaded.

Frequently asked questions
How do I compress an image to 20 KB?
Load your image on this page — it automatically finds the best quality that keeps the file under 20 KB. You'll see the final size before you download.
What if my photo can't reach 20 KB?
The tool lowers quality and, if needed, the dimensions to get as close as possible. If 20 KB is impossible without destroying the image, it shows you the smallest size it could achieve instead of pretending it worked.
Is my image uploaded?
No. Compression happens entirely in your browser — the file never leaves your device.
