Frequently asked questions
How do I make my photo exactly under 15 KB?+
Drop it here and the tool automatically lowers quality and, if required, dimensions until the JPEG is at or below 15 KB, then shows you the final size — so the portal will accept it.
Will a 15 KB photo still be clear enough?+
For most ID-sized photos and signatures, yes. Very strict caps on large originals force more compression, so start from a sensibly-sized scan for the best clarity.
Is my document image private?+
Yes — compression is 100% local. Your signature, photo or scan is never uploaded anywhere.
What format do I get back?+
A standard JPG, which every government and exam portal accepts. You can rename it if the form asks for a specific filename.
