Watermark PDF: Add a Text or Image Watermark Online

To add a watermark to a PDF, upload the file to PdfPeaks' Watermark PDF tool, type your watermark text or upload a logo, set its opacity, position and rotation, then apply it and download the new PDF. It's free, runs in your browser and needs no signup or software.

A watermark tells people what a document is, who it belongs to, or what it's allowed to be used for. PdfPeaks' Watermark PDF tool lets you stamp text like CONFIDENTIAL, DRAFT or PAID, or your own logo, across the pages of any PDF in a few clicks. You control how faint or bold it looks, where it sits and how it's angled. Nothing to install, no account to create. It's handy for anything from a company invoice to a copy of your CNIC that should only be used for one purpose.

How It Works

  1. Upload your PDF using the file picker or by dragging it in
  2. Choose a text watermark (type your own wording) or upload an image or logo
  3. Adjust the opacity, size, rotation and position until it looks right in the preview
  4. Click apply so the watermark is added across the pages
  5. Download the watermarked PDF to your device

Security & Privacy

Watermarking is done on a copy of your file. The original stays untouched on your device, and the uploaded PDF and the watermarked result are removed from our servers shortly after processing. No account is needed, and nothing is shared with third parties. That matters most for the documents people usually watermark: contracts, salary letters, bank statements and ID copies.

Common Use Cases

  1. Marking a CNIC or passport copy with "For bank account opening only" plus the date, so it can't be reused for something else
  2. Stamping CONFIDENTIAL or DRAFT on proposals, contracts and reports before they're shared
  3. Adding PAID or COPY to invoices and receipts
  4. Putting a company logo on quotations, brochures and catalogues
  5. Protecting lecture notes, past papers or ebooks you sell or share with your name or brand
  6. Labelling thesis or assignment drafts with a version and date before sending them to a supervisor

Tips for Best Results

  1. Keep the opacity low (around 20 to 30 percent) for logos and long text so the page stays readable
  2. A diagonal watermark is harder to crop out than one along the edge
  3. For ID copies, include both the purpose and the date, and make it big enough to cover the photo and number area
  4. Have a Word, Excel or PowerPoint file? Convert it to PDF first, then add the watermark here
  5. Preview a page with dense text before applying, so the watermark doesn't hide something important
  6. If the file is sensitive, add a password after watermarking so it can't be opened by anyone

Frequently Asked Questions

Upload your PDF, enter your watermark text or upload a logo, adjust the opacity, size and position, then apply it and download the result. There's no signup and no cost.

Yes. Upload your logo, then set its size, position and transparency so it sits behind or over the page content without hiding it.

No. This tool only adds watermarks. It doesn't strip existing ones, and a watermark that someone else placed on their document is there for a reason. If you added a watermark yourself and still have the original file, the easiest fix is to re-export it without one.

Word has a built-in option under the Design tab. Excel and PowerPoint don't have a one-click equivalent. The quickest route for any of them is to save the file as a PDF and add the watermark here.

Common choices are CONFIDENTIAL, DRAFT, PAID, COPY or your business name. For ID documents, something like "For [purpose] only, [date]" is more useful because it limits how the copy can be reused.

No. The watermark is layered over your existing pages, and the original text, images and layout are left as they are.

A determined person with a PDF editor may be able to. A watermark discourages misuse rather than blocking it, so for sensitive files, combine it with password protection.

Yes. Pick the PDF from your phone's storage or Files app, set your watermark and download the finished PDF to the same device.

No. The file is used only to create your watermarked copy and is deleted from our servers shortly after processing.
