Frequently Asked Questions
Can the watermark be removed?
The watermark is added as a semi-transparent image layer on each page. It deters casual copying, but anyone with PDF editing software could delete it. Don't rely on a watermark alone for security.
Does it support accented and non-Latin characters?
Yes. The text is drawn with your system's fonts, so accented letters, other scripts, and even emoji display correctly.
Is the original text still selectable?
Yes. The watermark is placed on top of the page without flattening it, so the original text stays selectable and searchable.
Is my PDF uploaded?
No. The watermark is applied in your browser, and the file never leaves your device.
