Why Choose Our PDF Watermark Tool

Text & Logo

Stamp custom text watermarks like DRAFT, CONFIDENTIAL, or SAMPLE across every page, or overlay your own company logo image for professional branding. Supports PNG, JPG, and SVG logos with transparent backgrounds.

Tile or Place

Repeat the watermark diagonally across the whole page for maximum coverage, or place it precisely in one of eight positions including corners, edges, and centre. Perfect for protecting intellectual property or marking documents for review.

Opacity & Colour

Fine-tune transparency from 5% to 100% and pick any colour so your content stays readable under the watermark. Use a faint stamp for internal drafts or a bold overlay for strong confidentiality notices.

Every Page

The watermark is applied to all pages at the correct dimensions automatically. Works with portrait, landscape, and mixed-orientation documents so you never need to watermark page by page.

Encrypted & Auto-Deleted

Your PDFs are transmitted over encrypted HTTPS and permanently deleted from our servers within minutes of processing. We never store, share, or read your documents — your files stay private.

No Desktop Software

Add watermark to PDF free online from any modern browser on Mac, Windows, iPhone, or Android. No Adobe Acrobat subscription, no desktop editor, no signup required — just upload and stamp.

Common Use Cases for Adding PDF Watermarks

Mark Documents as DRAFT or CONFIDENTIAL

Stamp every page of internal memos, reports, or proposals with a clear DRAFT or CONFIDENTIAL watermark so recipients know the document is not final and should not be distributed outside the intended audience.

Brand Proposals with Your Company Logo

Upload your company logo and overlay it across sales decks, client proposals, and pitch documents. A semi-transparent logo watermark reinforces brand identity on every page without obscuring the content.

Protect Intellectual Property

Add a tiled watermark across research papers, design files, or proprietary documentation to deter unauthorized copying and make it clear the content is owned and protected by your organization.

Watermark Contracts Before Review

Stamp contracts and legal agreements with REVIEW COPY or FOR APPROVAL ONLY before sending them to stakeholders. This prevents premature signing and signals that the terms may still change.

Add SAMPLE Stamps to Templates

Overlay a SAMPLE watermark on invoice templates, form templates, or example documents you share publicly. This lets people preview the layout while making it clear the file is not a live, binding document.

PDF Watermark FAQ

Quick answers about watermarking PDFs, tiling, opacity, and using logos.

How do I add a watermark to a PDF?

Upload your PDF, type your watermark text or upload a logo, then choose the opacity, colour, rotation, and whether to tile it across the page. Click 'Add Watermark & Download' and every page is stamped instantly while keeping the original content intact.

Can I stamp DRAFT or CONFIDENTIAL across every page?

Yes. Type your text (for example DRAFT, CONFIDENTIAL, or SAMPLE), set a diagonal rotation, and turn on tiling to repeat it across the whole page. Lower the opacity so the underlying text stays readable.

Can I use my company logo as the watermark?

Yes. Switch to the Logo option and upload a PNG (transparent logos look best). You can resize it, set its opacity, rotate it, and place it in a corner, the centre, or tiled across each page.

Does the watermark apply to all pages?

Yes, the watermark is applied to every page of the PDF at its correct dimensions, so it works with portrait, landscape, and mixed-orientation documents.

Will the watermark reduce my PDF quality?

No. The watermark is added as a vector overlay on top of your existing pages. The original text, images, and formatting are untouched, and the file size increase is negligible for text watermarks.

Is my PDF file secure?

Yes. Your file is uploaded over an encrypted HTTPS connection, processed on our server, and automatically deleted after processing. We never store, access, or share your documents.

Can I adjust how transparent the watermark is?

Yes. Use the opacity slider to make the watermark faint (so content stays readable) or bold (for a strong DRAFT/CONFIDENTIAL stamp). Any level from 5% to 100% is supported.
