How It Works

  1. Upload the base photo or document.
  2. Upload your signature image.
  3. The tool composites the signature onto the base image.
  4. Download the merged result.

Why This Is Separate From the General Logo Overlay Tool

This tool is set up specifically for the signature-on-document use case - positioning and scale defaults are tuned for a signature rather than a logo, which typically needs to be smaller and placed in a specific corner or designated signature area.

Frequently Asked Questions

Does my signature need a transparent background?

A signature scanned or photographed on plain white with the background removed (transparent) will overlay most cleanly onto the document.

Can I resize my signature to a specific dimension first?

Yes - use the Signature Resize tools (6cm x 2cm or 50mm x 20mm) to get your signature to an exact size before merging.
