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, color, size and opacity) and image watermarks (PNG, JPG formats supported). The watermark can be positioned anywhere on the page or tiled across the entire document.
Is there a file size limit?
Since processing happens in your browser, very large files (100+ MB) might take longer to process or could cause performance issues on older computers. For best results, we recommend files under 50MB.
Are my documents secure?
Absolutely! Your PDF files are processed locally in your browser and never uploaded to any server. This ensures complete privacy and security for your sensitive documents.
