Tips for Best Results

Create Clear Signatures

Sign with a dark pen on white paper, then photograph or scan. Crop closely around the signature. PNG with transparent background works best.

Size Your Signature

Standard signature width is 100-200 pixels. Adjust to fit the signature line on your document. Preview the result before finalizing.

Sign Multiple Pages

Select 'all' to add your signature to every page. Useful for contracts where each page needs to be initialed or signed.
