Compress Image to 50KB
50KB is a widely used photo upload limit on application forms and ID verification systems worldwide. This tool targets 50KB precisely, so you keep every bit of quality the limit allows instead of over-compressing to 25KB "just to be safe".

Frequently asked questions
What is the best quality I can get at 50KB?
For a typical headshot-style photo, 50KB comfortably holds a sharp 400–600px image. The tool searches for the highest JPEG quality that fits, so you automatically get the best result the limit allows.
Can I compress a PNG to 50KB?
Yes — upload a PNG and the tool converts it to JPG during compression, because JPG reaches small sizes far more efficiently. Forms with KB limits almost always expect JPG anyway.
Why did my file come out at 48KB and not exactly 50KB?
JPEG sizes move in steps, so the tool aims for the largest size that stays under your limit. A file a little below the cap is exactly what upload validators want; going even 1KB over means rejection.
