Resize Signature to 20KB
Upload your signature image and automatically clean it up — crops whitespace, converts to black on white, and compresses to 10KB or 20KB. Perfect for government exam forms.
How to Resize Your Digital Signature
Government exam forms like SSC, UPSC, Railway RRB, and bank exams require a digital signature image in specific dimensions and file sizes. The most common requirements are:
- Dimensions: 300×80 pixels or 140×60 pixels
- File size: 10KB to 20KB
- Format: JPEG/JPG only
- Background: White only
- Ink color: Black only
SizeSnap's Signature Processing Pipeline
When you upload a signature image, SizeSnap automatically:
- Detects the signature area and crops surrounding whitespace
- Converts to black ink on white background for clean, high-contrast output
- Resizes to 300×80 pixels (standard signature dimensions)
- Compresses to both 10KB and 20KB so you can choose the right size
- Strips all EXIF metadata for privacy
Tips for Scanning Your Signature
For the best results, sign on plain white paper with a black pen. Take a well-lit photograph straight above the paper, or use a scanner. Avoid shadows, creases, and colored backgrounds. SizeSnap can handle imperfect inputs, but cleaner originals produce better results.
Common Signature Upload Errors
- “File size exceeds limit” — Use SizeSnap to compress to the required size
- “Invalid dimensions” — Ensure your image is 300×80 or the required dimensions
- “Invalid format” — Convert to JPEG using our format selector
- “Image is blurry” — Start with a higher-quality scan or photo
