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.
