Adding a watermark to a PDF is one of the most common document branding tasks — whether you need to stamp CONFIDENTIAL across every page, tile your company logo for copyright protection, or mark a draft for internal review. Most tools either cost money, add their own watermark, or require uploading your file to a server. This tool does none of that. It runs entirely in your browser using pdf-lib, an open-source PDF manipulation library. You upload the file locally, configure your watermark (text or image, centered or tiled, any opacity and rotation), and download the result. The original file is never sent anywhere. You can also combine watermarks with page numbers and headers/footers in a single pass — no need to run the tool multiple times.

## How it works

1. **Upload Your PDF** — Select or drag and drop the PDF file you want to stamp with watermarks, page numbers, or headers.
2. **Enable & Configure** — Toggle on Watermark, Page Numbers, and/or Header & Footer. Customize text, position, opacity, and formatting for each.
3. **Download Stamped PDF** — All enabled stamps are applied in a single pass. Download your stamped PDF instantly.

## Use cases

- **Confidential Document Marking**: Stamp CONFIDENTIAL or INTERNAL across every page of sensitive reports before distribution to ensure recipients know the document's classification.
- **Brand Protection**: Tile your logo across PDF portfolios or proofs to prevent unauthorized use while sharing work with clients for review.
- **Draft Review Copies**: Mark manuscript PDFs as DRAFT before sending to reviewers. The diagonal watermark makes it clear this isn't the final version.
- **Academic Paper Marking**: Stamp student papers or exams with a department watermark for official record-keeping and to prevent unauthorized redistribution.

## Tips

- **Use Low Opacity for Readability**: Set opacity between 10-20% for text watermarks so the underlying content remains clearly readable. The default 15% works well for most documents.
- **Tile for Full Coverage**: Choose 'Tile' position to repeat the watermark across the entire page. This prevents someone from cropping out a single centered watermark.
- **Combine Multiple Stamps**: Enable Watermark + Page Numbers + Header & Footer all at once. The tool applies all three to the same PDF in a single pass.
- **Use Custom Page Ranges**: Apply watermarks to specific pages only — for example, skip the cover page by entering '2-10' in the custom range field.

## FAQ

### Is this tool really free?

Yes, 100% free with no limits, no watermarks added by us, and no registration. All processing runs in your browser.

### Can I add both text and image watermarks?

You can choose either text or image watermark per run. To add both, run the tool twice — first with text, then upload the result and add the image.

### Will my files be uploaded?

No. Everything runs locally in your browser using pdf-lib. Your PDF file never leaves your device.

### Can I watermark specific pages only?

Yes. Switch to 'Custom Range' and enter page numbers like '2-5, 8' to target specific pages.

### What image formats are supported for watermarks?

PNG and JPG images. PNG is recommended for logos as it supports transparency.
