When you need a 50 KB image
50 KB is the most common photo limit on online application forms: visa portals, job applications, scholarships, bank KYC and school admissions. A passport-size photo at 50 KB looks sharp.
Tips for a sharp result at 50 KB
If the portal also specifies pixel dimensions, set them first with the image resizer, then compress to 50 KB here. You can also crop away empty background with the crop tool before compressing.

Frequently asked questions
Will my image be exactly 50 KB?
It will be at or just below 50 KB, usually within a few KB. Staying slightly under prevents portals from rejecting it.
Can I compress a PNG or screenshot?
Yes. It is converted to JPG (or WebP if you choose), with transparent areas filled with the background colour.
Is it safe for ID documents?
Yes. The compression happens in your browser; the file is never sent to a server.
Why does the form still say my file is too large?
Some portals count 1 KB as 1,000 bytes. Set the target a few KB lower, for example 47 KB, and try again.
