Why Add a Watermark to a PDF?
Watermarks brand your documents and discourage casual misuse, making it clear who the document belongs to.
- Mark drafts and internal files with CONFIDENTIAL or DO NOT COPY to set expectations at a glance.
- Place your company logo on every page so documents you send look polished and consistent.
- Add copyright or author details to photos, contracts, and reports you distribute publicly.
- Identify which version or recipient a document came from when files are shared around.
How to Add a Watermark
Step 1: Upload Your PDF
Drag and drop your PDF into the upload area or click to browse. You can watermark several documents at once, and files up to 100MB each are supported.
Tip: if a document has a title page that should stay clean, you can watermark the rest and use a lighter mark on the cover.
Step 2: Customize Your Watermark
Choose between a text or image watermark. For text, type your phrase, set the font size (10 to 200), and pick a color. For an image, upload a PNG or JPG and set its scale. Then adjust opacity, rotation, and choose one of the seven positions on the page.
Step 3: Add Watermark and Download
Click Add Watermark. PDFit applies the mark to every page and downloads your watermarked file. If you processed several PDFs, they are bundled into a ZIP.
Frequently Asked Questions
What is the maximum file size I can watermark?
You can watermark PDFs up to 100MB per file. If your file is larger, compress it first and then add the watermark to the smaller copy.
Are my files uploaded to a server?
No. The whole process happens locally in your browser. Your PDF and your watermark image never leave your device, and nothing is stored anywhere.
Can I add a watermark on my phone or tablet?
Yes. The tool runs in any modern mobile browser, so you can watermark documents on a smartphone or tablet without installing an app.
Is this tool free, and do I need an account?
It is completely free. No account, no login, and no extra watermark added by the tool, just your own mark on your own document.
Does adding a watermark change the content of my PDF?
No. The watermark is drawn on top of each page, but your original text, images, and layout remain exactly the same underneath.
Should I use a text or an image watermark?
Use text for quick phrases like CONFIDENTIAL or your company name. Use an image when you want a logo, signature, or graphic. You can choose either type before processing.
What does the opacity setting do?
Opacity controls how see-through the watermark is, from 5% for a faint background mark to 100% for a fully solid one. A low opacity around 20% keeps documents readable.
Where can I place the watermark on the page?
There are seven positions to choose from: top left, top center, top right, center, bottom left, bottom center, and bottom right. The default is bottom left.
Does a watermark stop other people from copying my PDF?
No. A watermark is a visual mark and does not prevent copying or downloading. If you need real protection, use the Lock PDF tool to restrict printing and copying with a password.
Can I adjust the size and rotation of my watermark?
Yes. For text, the font size ranges from 10 to 200, and you can rotate the mark by -45, 0, or 45 degrees. For images, the scale ranges from 5% to 100%.
