10 KB is one of the tightest limits any form asks for — at this size, dimensions matter more than quality. ExactKB automatically finds the right combination of both, shrinking the image only as much as needed to slip under the limit.
Everything happens in your browser. Your file is never uploaded to a server, which matters when the image is a signature or an identity document.
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
Will a 10 KB image still be readable?
For signatures and simple images, yes. For detailed photos, expect visible quality loss — 10 KB is very small. ExactKB preserves as much detail as the limit allows.
What if the form also wants specific dimensions?
Enter the width and height in pixels and ExactKB will crop-and-fit to exactly those dimensions while hitting the KB target.
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.
