Exam and government forms want a small signature image with strict dimensions. Here's how to resize and compress your signature to 10–20KB in seconds.
The typical signature requirement
Online applications for exams like SSC, UPSC, IBPS and many recruitment portals ask you to upload a scanned signature that meets two rules at once: specific pixel dimensions (often around 140 × 60 px) and a small file size, usually between 10KB and 20KB. Meeting both by hand is fiddly.
Prepare your signature
- Sign on plain white paper with a dark pen.
- Scan it or take a well-lit photo directly from above.
- Crop closely around the signature so there's little empty space.

Upload your cropped signature, set the maximum width and height your form specifies, and choose your target KB. The tool fits the signature inside the box and compresses it to size.
