Set transparency from 5% (nearly invisible) to 100% (fully opaque). Typical watermarks use 20-40%.

Font Size
Choose font size from 12pt to 120pt. Larger sizes are more visible; smaller sizes are more subtle.
Color Picker

Frequently Asked Questions
Can I add a watermark to a PDF for free?
Yes — TryDocsy's PDF Watermark tool is completely free. No signup, no account, no upload to servers, and no file size limits beyond 100 MB.
Can I control the watermark opacity?
Yes — you can set the opacity from 5% to 100%. A lower opacity (20-30%) makes the watermark semi-transparent, which is typical for CONFIDENTIAL or DRAFT stamps.
Will the watermark be on every page?
Yes — the watermark is applied to every page of the PDF. The live preview shows the first page so you can see how it will look before downloading.
Can I add a watermark to a password-protected PDF?
No — you need to unlock the PDF first using the PDF Unlock tool, then add the watermark.
Can I remove a watermark added by TryDocsy?
Watermarks added by TryDocsy are embedded as text drawn directly on the page. They can be removed using a PDF editor, but this requires editing the PDF content layer.
What font is used for the watermark?
TryDocsy uses Helvetica Bold, a clean and widely-readable sans-serif font that works well for watermarks at any size.
