How to Add a Watermark to a PDF Online for Free

Protect and brand PDF documents with a custom text or image watermark on every page. Control position, opacity, size and rotation angle — no software, no account.

Text watermark vs image watermark

"CONFIDENTIAL", "DRAFT", "APPROVED", "FOR REVIEW ONLY" or your company name — text watermarks are the most common choice. Choose font, size, color and opacity. Image watermarks use a transparent PNG logo for professional branding. Diagonal placement is recommended for confidential documents as it covers more of the page area and is harder to crop away.

Watermark opacity and positioning

Opacity ranges from 5% (barely visible) to 100% (fully opaque). For legal proofs and drafts, use 30-50% opacity with diagonal rotation. For subtle branding, use 10-20% opacity. Position options: center, top-left, top-right, bottom-left, bottom-right, or custom X/Y offset.

FAQ

Can the watermark be removed from a PDF?

A watermark at high opacity over contrasting content is very difficult to remove cleanly. Low-opacity watermarks can sometimes be removed with advanced PDF editing tools.

Can I add a logo watermark?

Yes. Upload a transparent PNG of your logo and it will be applied at your chosen size and position on every page.

Is the watermark applied to every page?

Yes. By default the watermark is applied to all pages simultaneously.

Can I add text and image watermarks at the same time?

Apply text first, then re-upload the result to add an image watermark on top.

Does watermarking change the file size significantly?

Text watermarks add negligible size. Image watermarks may increase size slightly depending on the PNG complexity.

Will hyperlinks still work after watermarking?

Yes. Watermarks are added as an overlay layer. All hyperlinks, bookmarks and interactive elements remain fully functional.
