Add a Stamp
📌 How it works:
1️⃣ Open a PDF to add a stamp image.
2️⃣ Open a local stamp image, then click "Add to This Page" to show it in the preview.
3️⃣ Set the stamp width, opacity and rotation, and use manual dragging to position it.
4️⃣ Each page can have a different size and position. On another page, click "Add to This Page" again. Stamp size, opacity and rotation carry over from the previous page.
5️⃣ Blend Mode: Normal covers the page directly, useful for obscuring content. Multiply simulates a real stamp; stamp images with a white background work best, allowing black text to show through naturally. Darken is similar for a solid red stamp on white, but gradients or shadows may create hard edges. Multiply is recommended.

Frequently asked questions
Is the stamp automatically added to every page?
No. Click Add to This Page on each page that needs it. Settings carry over from the previous page, but each page can have its own size and position.
Is an image stamp a digital signature?
No. This tool adds a visual stamp image. It does not create a certificate-based digital signature or validate an existing signature.
