How it works
Select your recruitment exam or portal preset
Choose from SSC, India Post GDS, PAN Card, UPSC, IBPS, or select 'Custom Dimensions' to type custom pixel measurements and target KB caps.
Upload your signature photo
Drop a smartphone photo or scan of your signature. The tool automatically centers your handwriting and scales it to the required aspect ratio.
Toggle shadow cleaning or ink conversion
Enable 'Auto-Clean Grey Paper Shadows' to turn paper backgrounds pure white, or 'Convert Blue Ink to Black' before comparing the output with your active portal notice.
Download and verify the JPG
Review the live preview and file size counter. Download the JPG, then compare its dimensions and size with the active portal notice.
Frequently asked questions
Why do Indian exam portals reject signatures for incorrect aspect ratios?
Some portals validate the ratio between width and height. If the active notice specifies a 5:2 GDS image or a 7:3 SSC image, a square upload would not match that requirement. Always use the current notice for the exact values and error wording.
How does the tool target the 20KB or 50KB limit?
The engine uses multi-pass JPEG compression to target the selected preset's size range and displays the resulting size. Check the final file and compare it with the active portal notice because a preset is not an acceptance guarantee.
Should I sign in blue or black pen for government recruitment?
Ink instructions vary by application. If the active notice calls for black ink, the conversion option can create a black version for comparison; it does not replace the notice or guarantee acceptance.
What should I do if my photo has notebook lines across the signature?
Exam verification systems frequently reject signatures with horizontal notebook lines. Use our dedicated 'Remove Ruled Lines' tool from the Signature Studio Suite to erase lines while preserving handwriting strokes.
