About Compress Image to 20 KB
The 20 KB threshold is the standard photo specification for prominent Indian and Asian government recruitment bodies, including SSC (Staff Selection Commission), Railway Recruitment Boards (RRB), and banking entrance exams.
Our 20 KB tool focuses on retaining clean facial outlines and natural skin tones while discarding invisible high-frequency noise that inflates file size.

Frequently Asked Questions - Compress to 20 KB
Why does my portal reject my photo even when it looks small?
Portals check binary file size, not physical dimensions. A photo may look small on screen but still weigh 50 KB. This tool guarantees the file is under 20 KB (20,480 bytes).
Can I compress both JPG and PNG images to 20 KB?
Yes. PNG files will be converted to JPEG during compression because JPEG achieves significantly higher compression ratios for photographic images.
Is there any watermark on the downloaded 20 KB photo?
Never. All downloaded photos are 100% clean and free of watermarks.
