Important notes before downloading your signature.
Black Ink Required

Frequently Asked Questions
Everything you need to know about 10-20KB signature requirements.
How do I resize my signature to exactly 10KB - 20KB?
Upload your signature photo to this tool. The target size is automatically set to 20KB. The tool will adjust the compression quality to ensure your file falls between 10KB and 20KB. Download the output and check the final size.
Will the signature become blurry if I compress it to 10KB?
If your original signature is too large, compressing it under 20KB can slightly reduce quality. However, our tool balances compression carefully. If it looks blurry, try cropping out any extra white space before resizing.
What is the standard dimension for a 10-20KB signature?
Most exams (like SSC and IBPS) that require a 10-20KB signature also require it to be around 140 pixels in width and 60 pixels in height (or 4.0 cm x 2.0 cm). You can set these exact dimensions in the tool settings.
Why is 10 KB to 20 KB the universal standard for Indian exam signatures?
Government recruitment servers (NIC, SSC, IBPS, NTA) enforce this strict limit to conserve database bandwidth while ensuring legible signature verification.
Will compressing my signature to under 20 KB make it blurry?
No. Our intelligent optimization preserves crisp stroke contrast and sharp edges while stripping hidden EXIF metadata to reduce file size.
Can I convert PNG signatures into 10-20 KB JPG files?
Yes, the tool automatically converts PNG, WEBP, or HEIC signatures to web-standard JPG format within the 10KB–20KB target.
