Tips for a Clean Signature Removal

• High contrast: Use black ink on bright white paper — avoid coloured paper or light-coloured ink
• Avoid shadows: Photograph in diffuse daylight or under even artificial light — a single light source creates shadows
• High resolution: Photograph from 20–30cm above the signature — close enough to fill the frame
• Straight-on angle: Photographing at an angle distorts the signature shape
• Crop first: Crop the photo tightly around the signature before uploading for the best result

Compress the Signature File

A transparent PNG of a signature is typically 50–200KB. For embedding in emails or documents, this is usually fine. For bulk documents or web use, compress the PNG to reduce file size without losing the sharpness of the ink strokes.
