FAQ
Can the watermark be removed after applying?▾
The watermark is permanently embedded into the PDF content. Unlike some watermarking tools that add removable layers, PDFlys flattens the watermark into each page's content stream, making it part of the document. To get an unwatermarked version, keep a copy of your original file.
Will the watermark appear when printing?▾
Yes. The watermark is embedded in the page content and will appear when the document is printed. The 25% opacity ensures the watermark is visible but doesn't interfere with reading the underlying text and graphics.
Can I customize the watermark text?▾
Yes. While this preset uses "CONFIDENTIAL", you can change the text to anything you need — "DRAFT", "INTERNAL USE ONLY", "COPY", your company name, or any other text. Just edit the text field before processing your PDF.
