Why compress to this size?
50 KB is the classic passport-photo and government-form limit — tight enough to satisfy strict upload caps while keeping facial detail clear.
Frequently asked questions
How do I compress a photo to 50 KB?
Drop your file into the tool above, make sure the target is set to 50 KB, then click Compress image. The file downloads straight to your device once it's done — nothing is uploaded to get there.
Will this reduce image quality?
Some quality is traded for file size, but PhotoToolKit looks for the highest quality that still fits your target, so the result stays as sharp as your size limit allows.
Is this really free and private?
Yes. There's no account, no ads, and no upload — the image is compressed using your own browser and never leaves your device.
