Frequently Asked Questions
Is adding a watermark to a PDF free?
Watermark PDF is a Pro feature, available on the PDF.it Pro plan at $7.99/month. Pro includes unlimited use and access to all PDF tools.
What types of watermarks can I add?
You can add custom text watermarks — such as "Confidential", "Draft", or your company name — as well as image watermarks like a logo or stamp. You control the position, size, and opacity.
Will the watermark appear on every page?
Yes. The watermark is applied to all pages of the PDF by default, ensuring consistent branding and protection throughout the entire document.
Will watermarking affect the rest of my PDF content?
No. Adding a watermark only overlays the selected text or image onto your pages. All existing text, images, fonts, and formatting remain completely untouched.
Are my files secure when I upload them?
Yes. All files are transferred over HTTPS, processed securely, and automatically deleted after your session. We never store or share your documents.
What is the maximum file size I can watermark?
Pro and Business accounts can upload files up to 200MB.
