50 KB is the default photo ceiling on hundreds of application systems — Indian exam boards, bank recruitment portals, university forms, and older government sites worldwide. ExactKB compresses straight to the target instead of making you loop through trial and error.

How it works
- Check the target. This page is preset for the spec above — adjust any number to match your exact form.
- Drop your photo. ExactKB finds the best quality and dimensions that land inside the size window — including padding files up when a form has a minimum size.
- Download. The file fits the requirement on the first try.
FAQ
Can I do many photos at once?
Yes — drop multiple files and each is compressed to the same target.
Which formats can I upload?
JPG, PNG, WebP, GIF and BMP. Output is JPG (smallest) or PNG.
Is my photo uploaded to a server?
No. ExactKB runs entirely in your browser. Your file never leaves your device — this page even works offline.
