Frequently Asked Questions
The watermark is drawn directly onto the page content, so it becomes a permanent part of the document — the same way a printed stamp would be. Keep your original file if you need an unmarked copy.
Yes — upload as many files as you like and the same watermark settings will be applied to all of them.
By default the watermark is drawn semi-transparently across the center of the page — use the opacity slider to make it as subtle or bold as you need.
Yes. Watermarking happens entirely on your own device in your browser — your files are never transmitted over the internet.
The current tool supports text watermarks only. Image/logo watermarks are planned for a future update.
