Why 6cm x 2cm?
This specific aspect ratio (3:1) is the standard dimension for digital signatures in many online application forms, including Banking exams, SSC, and UPSC portals. If your aspect ratio is incorrect, the signature might look stretched or compressed on the admit card.
How to use this tool effectively:
- Upload a Clear Scan: Use a photo of your signature taken on plain white paper. Good lighting ensures the background stays white.
- DPI Matters: Most official forms ask for "300 DPI" or "High Quality". Keep the setting at 300 for the sharpest print quality. If you need a smaller file size (KB), you can lower it to 200 or 150.
- Locked Aspect Ratio: We have locked the cropping box to 3:1. This ensures that no matter how you zoom or move the box, the final output will always be mathematically perfect for the 6cm x 2cm requirement.
Understanding Image Dimensions for Exams
Most government portals reject signatures if they don't match exact pixel calculations. When you convert 6cm x 2cm at 300 DPI, the math works out to roughly 709 x 236 pixels. If you try to do this manually in Paint or Photoshop, getting the crop exactly right without distorting the text is difficult.
Common Issues & Fixes
1. "File Size Too Large":
If the portal says your file must be under 20KB or 50KB, resizing dimensions is the first step. If the output from this tool is still too big, use our Image Compressor to lower the KB count without changing the 6x2 cm size.
2. "Signature unclear":
This happens if you take a photo in low light. Always sign with a thick black pen on white paper. Avoid blue ink if the instructions specify black ink only.
Data Privacy Note

Frequently Asked Questions
Q: Can I use this for photos instead of signatures?
A: Yes, but photos typically require a 3.5cm x 4.5cm ratio. This tool is specifically locked to the wider 6x2 cm format suitable for signatures or thumb impressions.
Q: How do I reduce the file size after resizing?
A: The tool optimizes the image automatically. However, if you need a specific KB limit (e.g., under 10KB), try lowering the DPI setting to 200 before clicking download.
