Everything you need to know about privacy, performance, and supported formats.
What is the standard aspect ratio for signature uploads in online forms?
Most exam and government portals (such as SSC, IBPS, UPSC, and state PSCs) require a 3:1 (width to height) rectangular signature ratio (typically 140x60 pixels or under 20KB-50KB).
How do I crop a signature cleanly from a photo taken on white paper?
Upload the photo of your signed paper, click the 'Signature 3:1' preset, adjust the bounding box tightly around your signature strokes, and click Crop to export a crisp signature image.
Can I rotate and straighten a tilted signature before downloading?
Yes! Use the built-in 90° rotation and horizontal/vertical flip buttons on the toolbar to align your signature perfectly before cropping.
