Why Do Portals Require Exactly a 20 KB Size?
In the modern era of applying to government exams, SSC, banking, or corporate jobs, you're inevitably asked to upload "a digital signature below 50 KB but strictly above 20 KB." Why? A scanned signature file that is just 8 or 12 KB is often terribly pixelated—an automated rejection by optical verification systems. The instruction to increase photo size to 20 kb isn't arbitrary; it enforces legibility for administrative review.
How to Increase Signature Size to 20 KB
Instead of manually expanding your image boundaries in Paint, which creates blur, our tool strictly recalculates the internal image compression ratio. We reconstruct the pixels at a maximum JPG quality boundary. If 100% quality is still short of 20 KB, the canvas subtly upscales the visual data. This guarantees that when you increase photo kb to 20, your signature's ink lines remain crisp and dark, free of distortion.
Is My Signature Safe?
Yes. A digital signature is equivalent to your identity. Using random web utilities that upload your signature is extremely dangerous. Your file is resized entirely locally using HTML5. No packet of data is transmitted to our servers—ever.
