Frequently asked questions
Can the watermark be removed?
It’s added as page content, but anyone with PDF editing software could remove it. Combine it with password protection to limit editing.
Is my PDF uploaded to a server?
No. The PDF is processed by your browser on your own device and never leaves it. Closing the page discards everything.
