RiverDIY / PDF tools / Watermark PDF
Add a watermark to a PDF
Mark documents as DRAFT, CONFIDENTIAL or COPY before you share them. Choose the text, size, angle, colour and how faint it is.
How it works
Three steps, and your file never leaves this device.
- Choose the PDF.
- Type the text and set its look.
- Download the watermarked PDF.
Questions
Good to know
Can I watermark ID copies?
Yes, and it is a good idea: a line such as "Copy for rental application only" makes a stolen copy less useful. Because nothing is uploaded, your ID stays on your device.
Is RiverDIY really free?
Yes. Every tool is free for one file at a time (five for merging and images to PDF), up to 50 MB a file. RiverDIY Pro (US$19, paid once) adds whole batches, big files and ZIP downloads.
Does it work offline?
Yes. After your first visit, the tools are kept in your browser; on a phone you can add RiverDIY to the home screen.
