Why Choose Dely PDF

Turn a Photo Into a Clean, Transparent Signature

Snap a photo of your signature on paper. Its background is automatically removed, leaving a crisp, transparent signature that blends naturally onto any page.

Recolor Any Signature

Change a drawn or photo-based signature to blue, black, or any color you like, without redrawing it or retaking the photo.

Place It Exactly Where You Want

Place your signature or a text box anywhere on any page, then drag, resize, or rotate it until it fits naturally.

Save Signatures for Reuse

Save a signature once and reuse it on future documents. Free accounts can keep up to 3 saved signatures; Dely PDF Pro removes the limit.
