Currently, you can add one watermark per processing session. You can process the same file multiple times to add multiple watermarks, or create a combined watermark image that includes both text and graphics.
We support PNG and JPG image formats. For best results, especially with transparency effects, we recommend using PNG files with transparent backgrounds.
Yes! Choose from five preset positions (center, corners), and you can rotate the watermark up to 90 degrees in either direction for diagonal placement.
Try increasing the opacity, changing the color for better contrast with the background, or adjusting the font size. Dark watermarks work better on light backgrounds, and vice versa.
Absolutely! All processing happens locally in your browser. Your files never leave your device and are never uploaded to any server. We take privacy and security seriously.
Once a watermark is added to a PDF, it becomes part of the document. To remove it, you would need to use specialized PDF editing software. We recommend previewing carefully before downloading.
