Online exam and government form portals are strict: they want your signature at an exact size (often 140×60 pixels) and under a tiny file limit (usually 10–20KB) as a JPG. Upload one that is even slightly off and it gets rejected. Here is how to resize your signature to the exact spec in seconds — free, and without your signature ever leaving your device.
Open Signature ResizerWhat Size Should a Signature Be?
Most Indian exam and banking forms (UPSC, SSC, IBPS, and similar) ask for:
- Dimensions: around 140×60 pixels
- File size: 10–20KB maximum
- Format: JPG/JPEG
- Background: white (not transparent)
Always check your specific form — some want 3.5×1.5 cm or a different KB limit. The tool lets you enter exact values.
How to Resize Your Signature in 3 Steps
- 1Sign on white paper with a dark pen, photograph or scan it, and open the WowShortcuts Signature Resizer.
- 2Pick your form preset (e.g. UPSC 140×60, ≤20KB) or type the exact width, height, and max KB.
- 3Download the resized JPG — it is automatically compressed to fit under the size limit.
White Background vs Transparent
Forms almost always require a white background JPG — choose that option. Transparent PNG is only for placing your signature onto documents (like a contract), not for form uploads.
If your form rejects the file, double-check it wants JPG (not PNG) and that the KB is under the stated limit.
Tips for a Clean Signature
- Use a bold dark pen on bright white paper
- Photograph in even light with no shadows
- Crop close around the signature before resizing
- Keep an original high-res copy for other uses
Conclusion
Getting a signature to an exact pixel and KB size is fiddly by hand but instant with the right tool. Use the WowShortcuts Signature Resizer to hit any form spec — free, private, and with built-in presets for common exams.
