One PDF. Text uses a built-in font that supports Latin characters.
This tool draws plain text onto the page. It does not create editable comments, highlights, or drawings, and it cannot change existing text.
The built-in font supports Latin letters, numbers, and common punctuation. Other scripts are not supported.
A watermark is visual only. Anyone with PDF editing software may be able to remove it.
File handling: This tool runs in your browser. Your PDF is read and processed in the tab on your device, and Pixuna's code does not upload it to a server. You can confirm this in your browser's network panel.
