PDF Watermark
Add text or image watermarks to PDF with tile mode and batch processing. 100% private, runs in your browser.
How do I add a watermark to a PDF?
Upload your PDF file, choose text or image watermark, adjust settings like size, opacity, rotation, color, and position, then click Add Watermark. The watermarked PDF will be downloaded automatically.
Can I use an image as a watermark?
Yes, you can upload any image (PNG, JPG, SVG) as a watermark. Adjust its size, opacity, and position just like a text watermark.
What is tile/repeat watermark mode?
Tile mode places the watermark multiple times across each page in a grid pattern. You can control the horizontal and vertical spacing between watermarks to achieve the desired density.
Can I watermark multiple PDF files at once?
Yes, you can select multiple PDF files and apply the same watermark settings to all of them in one batch operation.
Are my PDF files safe and private?
Yes, all processing happens locally in your browser. Your PDF files are never uploaded to any server, ensuring complete privacy and data security.
Can I customize the watermark appearance?
Yes, you can customize the watermark text or image, font size, opacity, rotation angle, color, position, and enable tile mode with adjustable spacing.
Is this PDF watermark tool free to use?
Yes, this tool is completely free. No registration, no watermarks on our watermarks, and no usage limits.
Do I need to install any software?
No installation needed. This tool runs entirely in your web browser. Just open the page and start adding watermarks to your PDFs.
What is the maximum file size supported?
There is no hard file size limit since processing happens locally. However, very large files may take longer depending on your device performance.
Can I remove a watermark from a PDF?
This tool is designed for adding watermarks. To remove watermarks, you would need the original unwatermarked PDF file.
How to Use PDF Watermark
Stamp text or image watermarks onto every page of a PDF with tiling, rotation and opacity control — processed entirely in your browser, nothing is uploaded.
- Open the Text tab, type your Watermark Text and set Font Size and Color, or switch to the Image tab and pick a Watermark Image with its Scale.
- Choose a Position preset: Diagonal, Center, Top or Bottom, or select Repeat to tile the mark across the whole page.
- Adjust Opacity and Rotation (degrees) until the mark is visible but does not obscure the content.
- When using Repeat, raise Spacing so the tiled marks stay evenly distributed and less intrusive.
- Apply the watermark and download the stamped PDF.
Low Opacity combined with the Diagonal preset gives the classic draft look; use Repeat with wider Spacing to protect content from casual screenshots.
