Frequently Asked Questions
How does this PDF watermark tool work?
Upload your PDF, choose text or image watermark, set the position and opacity, then click Apply. The watermarked PDF is generated directly in your browser and ready to download. Your file never leaves your device.
Should I use a text or image watermark?
Use text watermarks for labels like CONFIDENTIAL, DRAFT, or COPY — they are lightweight and easy to edit. Use image watermarks for logos, signatures, or branded stamps. Both work the same way and can be placed anywhere on the page.
Is my PDF uploaded to a server?
No. All processing happens locally in your browser using JavaScript. Your PDF is never uploaded, stored, or transmitted anywhere. This is the most private way to watermark a PDF online.
What is the maximum file size?
Since everything runs in your browser, the limit depends on your device's memory. Most PDFs under 100 MB work smoothly. Very large files may slow down older devices.
Is this tool free to use?
Yes, completely free with no limits, no signup, and no watermark from us added to your file. You can watermark as many PDFs as you want.
Can I apply different watermarks to different pages?
You can choose which pages to watermark — all pages, a specific range, or only odd or even pages. To apply multiple different watermarks, run the tool again on the output file.
Can this tool remove watermarks from a PDF?
No, this tool only adds watermarks. Removing watermarks from existing PDFs is a different process and is often restricted by copyright law depending on the document.
