Privacy and data handling
Input and output are processed by the current browser tab. The site has no content upload API and does not write your content to an account or cloud storage.
Formats and limitations
For broad font support, text is rendered to a transparent browser canvas before being placed in the PDF, so watermark text is not selectable.
Frequently asked questions
Does it support non-Latin text?
Usually yes, because the browser renders the text image instead of relying on built-in PDF fonts.
