FAQ
Is the stamp background transparent?
Yes. The "Transparent PNG" export has no background, so it layers cleanly on any colored PDF or document.
Can I use it in Word or Google Docs?
Yes. Insert the PNG as an image, then set text-wrapping to "In front of text" so it overlays content like a real stamp.
What is the arc text (company name)?
On circle and seal stamps, your company name arches around the top of the stamp inside the outer ring — like an official notary seal.
What does opacity control?
Lower opacity simulates a lightly inked stamp or a "watermark" effect. 100% is fully opaque — looks freshly stamped.
Can I save my stamp design?
Yes. Log in to BrieflyGo and click "Save to my account" — your stamp syncs to your dashboard for reuse.

Pro tip
For a more authentic look, lower the opacity to 75–85% and rotate the stamp slightly (−10° to −20°). This mimics a real rubber stamp applied by hand.
