Frequently Asked Questions
Can I add a watermark to every page automatically?
Yes — the watermark is applied to all pages in the PDF by default. You can optionally select specific page ranges if needed.
Can I remove a watermark added by this tool?
Watermarks added by PDF HUB 24 are embedded into the page content. They cannot be removed without re-editing the source PDF. Use our tool intentionally for final document versions.
Does the watermark affect PDF text searchability?
No — the watermark is added as an overlay layer. The original text remains searchable and selectable beneath it.
Can I add a transparent or semi-transparent watermark?
Yes. Use the opacity slider to set any transparency level from 10% to 100%. Most professional watermarks use 20–40% opacity to remain readable without obscuring the document.
Is there a limit on PDF file size for watermarking?
No hard limit. Large PDFs with many pages may take a few extra seconds to process, but all file sizes are supported.
