Compress Signature for IBPS SIG
Optimize signatures and fingerprints under strict size limits. Clean background contrast and scale dimensions.
Compress and Clean Signature and Thumb Images under 20KB
Signature and left thumb impression uploads on exam portals usually have strict requirements, requiring files to be between 10KB and 20KB. Furthermore, shadow-heavy phone camera scans can result in low-contrast signatures which get rejected. Our tool lets you resize dimensions, increase contrast to create a clean white background, and compress files secure to ensure compliance under 20KB.

Frequently Asked Questions
Find answers to common questions about our free online tools.
Does this tool support left thumb impressions?
- Yes. Left thumb impressions follow the same size guidelines (usually under 20KB) and clean background requirements as signatures. You can crop, clean, and compress them here.
What color ink should I use for signatures?
- Most portals prefer black or blue ink on plain white paper. Avoid ruled paper or background shadows, as automated screening systems might reject them.
Will my signature lose its original lines?
- No, the image compression algorithms preserve line outlines while shrinking the solid background data to keep the file size minimal.
