UPSC and major banking exams require uploading a scanned signature that fits specific file size limits. This resizer helps you crop and compress your signature under 50KB in seconds.
Steps to Resize Signature to 50KB
1. Click the **Go to Signature Resizer** button.
2. Upload your signature scan.
3. Select your target dimensions (e.g., UPSC 350x350 px or Bank Exam 140x60 px).
4. Set the target file size slider to **50KB**.
5. Download the optimized JPEG.
Sizing Guidelines
- **UPSC forms**: Minimum 350x350 pixels, target size: 20-300KB (under 50KB recommended).
- **Bank forms**: 140 x 60 pixels, target size: 10-20KB (some state banks accept up to 50KB).
Why UPSC Guidelines Require Equal Aspect Ratios
The Union Public Service Commission (UPSC) uses a specific system design that requires signatures and photos to be uploaded in square boxes (minimum 350x350 pixels, maximum 1000x1000 pixels). If you upload a signature with a wide aspect ratio, it will stretch or look compressed, resulting in application holds. Our tool lets you crop your signature into a square ratio while centering the active signature content, ensuring the final output displays perfectly inside the UPSC OTR dashboard.
