"Signature must not exceed 20 KB" — if you've applied to any government exam or job portal, you've met this message. Regular compressors make you guess a quality setting and retry until the portal stops rejecting you. ExactKB targets 20 KB directly and lands inside it.
If your form specifies a window like 10–20 KB, set the minimum too: ExactKB will pad the file up if it compresses below the floor, which is a common hidden reason portals reject files.
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
My portal says 10–20 KB. What do I enter?
Min 10, Max 20. ExactKB guarantees the output lands inside that window — including growing the file if it comes out too small.
Is my photo private?
Completely. Compression runs inside your browser; the image never leaves your device.
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.
