FAQ
Which format is best for a 20KB signature upload?
JPEG on a plain white background works best. JPEG hits a strict 20KB target reliably, and white is the background most forms require.
Does my signature leave my browser?
No. Signatures are processed in your browser, so the image never leaves your device.
Common situations for this workflow
Government exam portals (SSC, UPSC, banking, railways) that cap the signature upload at 20KB.
Online registration forms that reject any signature image larger than 20KB.
Forms where the photo and the signature must each be uploaded under their own small KB limit.
Checklist before you upload
Scan or photograph your signature on plain white paper, then crop tightly to the ink.
Start with JPEG - it reaches a 20KB signature target far more reliably than PNG.
Keep dimensions small (often around 160x60 px) so the signature stays crisp under 20KB.
Tips to hit the target faster
20KB is comfortable for a signature, so you rarely need to over-compress - keep it legible.
A dark-ink signature on a clean white background compresses cleanly at this size.
Aim slightly under 20KB so strict exam portals still accept the upload.
