Frequently Asked Questions
Is my PDF uploaded to a server?
No. The watermark is added entirely in your browser using JavaScript. Your document never leaves your device.
Can I remove the watermark later?
No. The watermark is burned into the PDF content. Keep your original file if you need an unmarked version.
