Resize Signature to 4x2 cm Online
SSC CGL, SSC CHSL, and many state PSC notifications specify signature dimensions as "4 cm x 2 cm." This tool converts those physical measurements to pixels (at 200 DPI: 315 x 157 px) and resizes your signature accordingly - so you don't have to do the math yourself.

How it works
Upload your cropped signature
Use a tightly cropped image - just the ink, not the full page.
Resize to 4x2 cm
Click the button above. The resizer converts cm to pixels automatically and scales your signature.
Compress if needed
If the portal also requires 10KB-20KB, run the resized image through the signature compressor.
Frequently asked questions
How many pixels is 4x2 cm?
At 200 DPI (the most common standard for Indian exam forms), 4 cm = 315 pixels and 2 cm = 157 pixels. At 300 DPI, it would be 472 x 236 pixels. Always check your notification for the required DPI.
Why does the portal reject my 4x2 cm signature?
The portal likely checks pixels, not centimeters. If your image editor set the wrong DPI, the pixel dimensions may be off. This tool calculates the correct pixels from cm so there's no mismatch.
Should I resize or compress first?
Always resize first. Changing dimensions changes the file size, so compressing before resizing wastes effort. Resize to 4x2 cm, then compress to 10-20KB.
