FAQ

Is my PDF uploaded anywhere?

No. Watermarking runs entirely in your browser.

Can I use an image as a watermark?

Wave 2 supports text only. Image watermarks are planned.

Does this remove existing watermarks?

No — it adds a new watermark on top. There's no reliable way to remove watermarks from arbitrary PDFs.

What's a good opacity for a DRAFT stamp?

0.2–0.3 with a 60–80pt diagonal red or gray is the common pattern.
