Which stamps can I add to a PDF?

CONFIDENTIAL, DRAFT and APPROVED are built in, and Custom lets you write your own text, such as COPY, VOID or PRIVILEGED. You choose the position, size, colour, angle and opacity.

Can a PDF stamp be removed by the recipient?

Not with a click. noll draws the stamp into the page content instead of adding a comment, so it can't be hidden or deleted like a sticker. Anyone with a PDF editor can still edit page content, so treat a stamp as a label, not as protection.

What preset stamps are available?

Common presets include CONFIDENTIAL, DRAFT, APPROVED, COPY, VOID, FINAL, FOR REVIEW, PRELIMINARY, SAMPLE, and NOT FOR DISTRIBUTION. You can also create custom stamps with any text.

Can I adjust the stamp opacity?

Yes. Stamps can be set from fully opaque to nearly transparent. Semi-transparent stamps (around 30-50% opacity) are commonly used as watermark-style overlays that mark the document without obscuring the content.

Can I place the stamp at an angle?

Yes. Stamps can be rotated to any angle. The diagonal across the page (typically 45 degrees) is the most common rotation for status stamps like DRAFT and CONFIDENTIAL.

How is this different from adding a watermark?

Stamps and watermarks serve similar purposes. Stamps are typically bold, prominent markings meant to be clearly noticed (like 'APPROVED'). Watermarks are typically subtle, semi-transparent background text. Both are applied as overlays, but stamps emphasize visibility while watermarks emphasize subtlety.
