Best Practices for Scanning Signatures

  • Use unruled pure white paper without watermarks, gridlines, or notebook margins.
  • Sign with a dark black or dark blue ballpoint pen. Avoid gel pens that bleed into paper fibers.
  • Crop tightly around your signature before resizing to prevent excessive white margins.

Custom KB Signature Resizer FAQs

How do I resize my signature to a specific KB size?

Set your desired minimum KB and maximum KB targets in the interactive controls above, then upload your signature image. Our binary-search compression algorithm adjusts the JPEG quality until the resulting file falls exactly inside your specified target bracket.

Can I change both dimensions (width & height) and KB size together?

Yes. You can customize the exact canvas width and height in pixels along with the minimum and maximum file weight in KB. The image will be drawn onto a pure white canvas background and compressed to your exact specifications.

What are the most common signature KB ranges for online applications?

The most widespread standard is 10 KB to 20 KB (used by SSC, IBPS, SBI, and state boards). Other portals, such as UPSC and GATE, accept signatures up to 50 KB or 100 KB, while passport and visa applications often allow 20 KB to 300 KB.

Are my signature files stored on your servers?

Never. All processing happens 100% inside your web browser using HTML5 Canvas. Your signature file is never uploaded to any remote server or stored in any database.
