Frequently asked questions
What's a good watermark setup?
For a classic look use uppercase text (e.g. DRAFT), diagonal placement, gray color and 15–25% opacity — visible without hiding the content.
Is the watermark permanent?
In the new file, yes — it's drawn into the page content like ink. Your original file stays untouched on your device.
Is my PDF uploaded?
No — often you're watermarking precisely because a document is sensitive. It never leaves your device.
