Frequently Asked Questions
Everything you need to know about Signature Tool.
What is the standard size for signature upload in online forms?
Most government and exam portals require signatures between 140x60 px and 300x80 px, weighing strictly between 10KB and 30KB.
How can I make my signature background transparent?
Export in PNG format with 'Transparent' padding. Our engine preserves ink line opacity while leaving the canvas background 100% transparent.
How to make sure a signature stays clear under 30KB?
Our adaptive downsampler sharpens dark strokes before encoding so pen curves remain intact without pixelated breaks.
