Frequently asked questions
Is watermarking a PDF free?
Yes. ToolPT's Watermark PDF tool is completely free, and we never add our own watermark to your file.
Is my PDF uploaded to a server?
No. Watermarking happens locally in your browser, so your document stays private.
Can I use my logo as a watermark?
Yes. Switch to Image mode and upload a PNG or JPG — transparent PNGs work best for logos.
Does the watermark apply to every page?
Yes. The watermark is stamped on all pages of the PDF.
