Frequently Asked Questions
Can I control how visible the watermark is?
Yes. Use the opacity slider to set transparency between 10% and 90%. A lower value makes the watermark more subtle, while a higher value makes it more prominent.
What angle is the watermark displayed at?
By default the watermark is rotated at 45 degrees diagonally across the page, but you can change this to any angle using the rotation input.
Will the watermark appear on every page?
Yes, the watermark is applied to every page of the PDF document automatically.
Is the watermark permanent?
The watermark is embedded into the PDF content, making it persistent. However, it is not cryptographically enforced — determined users with PDF editing tools could attempt to remove it.
Are my files uploaded to a server?
No. All processing happens entirely in your browser. Your PDF never leaves your device, keeping your files completely private.
