FAQ
Which format and background should a signature use?
Use JPEG on a plain white background. It reaches a strict 30KB target reliably and matches what most forms require.
Is my signature stored on a server?
No. Processing happens in your browser, so your signature image never leaves your device.
Common situations for this workflow
Government exam portals that cap the signature upload at 30KB.
Registration forms that sit between the 20KB and 50KB signature limits.
Forms where the photo and the signature each have their own KB cap.
Checklist before you upload
Scan or photograph your signature on plain white paper and crop tightly to the ink.
Keep the file in JPEG - it hits a 30KB signature target reliably.
Match the listed pixel dimensions when the portal specifies width and height.
Tips to hit the target faster
30KB is comfortable for a signature, so keep it sharp rather than over-compressing.
Dark ink on a clean white background compresses cleanly at this size.
Aim slightly under 30KB so a strict exam portal still accepts the upload.
