Frequently asked questions
Is the watermark applied to every page?
Yes — the watermark is stamped across all pages of the document at once.
Can the watermark be removed later?
It's merged into the page content on export, so keep your original if you might need an unmarked copy.
Can I control how visible it is?
Yes — adjust the opacity to make it a faint background or a bold, obvious stamp.
Is my file uploaded in the process?
No — everything runs locally in your browser; nothing is uploaded.
