Frequently Asked Questions
Is this PDF watermark tool really free?
Yes! Our online PDF watermark adder is completely free to use with no hidden charges. You can watermark as many PDFs as you need without any limitations.
What types of watermarks can I add?
You can add both text watermarks (with customizable font, size, color and opacity) and image watermarks (PNG, JPG formats). The watermarks can be positioned and rotated as needed.
Is there a file size limit?
Our tool can handle most standard PDF files. Very large files (100+ pages) may take longer to process depending on your device's capabilities.
Can I remove a watermark after adding it?
Once a watermark is added to a PDF, it becomes part of the document content. You would need specialized PDF editing software to remove it, which is why you should always keep an original unwatermarked copy.
