Pro Watermarking Tips

Using the Opacity Slider

Transparency is key. We recommend setting your watermark opacity to between 15% and 30%. This makes it clear that the document is protected without making the text underneath hard to read.

Confidentiality Marking

For legal or business documents, placing a diagonal 'CONFIDENTIAL' or 'INTERNAL USE ONLY' text watermark across the center is the standard way to prevent unauthorized distribution.

Branding for Portfolios

If you're a freelancer sending out work samples, adding a small logo image watermark in the bottom corner of every page is a great way to maintain ownership while still appearing professional.

Frequently Asked Questions

Is watermarking PDFs free?

Yes, our tool is free to use with no hidden fees, no credit cards required, and no usage limits.

Do I have to upload my doc to your server?

No. Your documents are 100% safe because the processing only happens locally on your computer in your web browser. We never see your files.

Can I add more than one watermark?

Currently, you can add one text or image watermark per pass. If you need both, just run the document through the tool a second time.

Will the watermark appear on every page?

Yes, our tool automatically applies your watermark to all pages of the PDF to ensure consistent protection throughout the whole document.

Which image formats can I use for logo watermarks?

We support PNG, JPG, and WebP. For the best result, we recommend using a PNG with a transparent background for your logo.

Can I change the font of the text watermark?

Yes, we provide several professional font options so you can match the style of your document.

What happens if I make a mistake?

Your original file on your computer is never touched. We create a copy with the watermark. If you don't like the result, just try again with new settings.

Can I remove a watermark with this tool?

No. This tool is for adding permanent watermarks. Removing a flattened watermark requires specialized software and is often restricted by copyright.

Does it work on password-protected PDFs?

You will need to unlock the PDF first using its password before our watermarking tool can modify the file.

Will adding a watermark increase the file size?

Only slightly. Text watermarks add almost no size, while image watermarks will add depending on the quality of the image you upload.

Can I rotate the watermark?

Yes, you have full 360-degree rotation control, allowing you to place text at a professional 45-degree angle.

Do I need to install Adobe to use this?

Not at all. This works in any modern web browser like Chrome, Safari, or Edge without any external software.
