Open PDF Sign tool

Stamp Maker creates transparent PNG seals or handwritten signatures for e-signing.

Seals that are too dark hide nearby text; too light get rejected. Export transparent PNG, then size it on a real PDF in PDF Sign.

Tip — Export with a transparent background so stamps sit cleanly on PDFs.

Stamp or handwritten signature?

Both — circular stamp text or canvas signature strokes.

Remove the background?

Export PNG with transparency; white backgrounds show as boxes on PDFs.

How do I place it on a PDF?

Use PDF Sign or PDF Add Image with the downloaded PNG.
