Add a watermark to a PDF
Add a text or image watermark to a PDF, for free. There is no usage limit. Your PDF is processed in your browser and never uploaded. Choose the opacity, angle and position, and apply it to all pages or the pages you choose. Place it once or repeat it across the page. You can open PDFs of up to 200 MB per file (100 MB on phones and tablets).
You can open one PDF at a time (up to 200 MB on this device). The PDF is processed in your browser and never uploaded.

About PDF watermarks
The watermark is laid lightly over the page content. With "Text", the text you enter is sized to fit the page or set to the size you specify. With "Image", an image such as a logo is sized as a share of the page width. Transparent parts of a PNG stay transparent. The preview shows pages with the watermark actually applied.
The original content is not rewritten, so text, images, bookmarks, form fields and tags stay as they are. Watermark text is embedded in the PDF, so it looks the same on any device. A font of a few MB is fetched once, only when text is used. The text and images you enter are never uploaded.

Frequently asked questions
Is my PDF uploaded?
No. Opening the PDF, adding the watermark and saving all happen in the browser on your device. Statistics that help us fix bugs (the page count range, the range of how many pages were watermarked, text or image, the kind of position, error types and so on) are sent to this site's server. They do not include the content of the PDF, file names, watermark text or images, or passwords. You can turn the statistics off with the "Send processing statistics" switch at the bottom of the page.
Can I watermark a password-protected PDF or one with editing restricted?
Yes. A password-protected PDF opens once you enter its open password. If the author has restricted changing the content, you cannot add a watermark until you enter the permissions password. This tool does not guess passwords, so if you do not know the permissions password, ask the person who created the PDF. The original PDF's encryption stays as it is in the saved PDF.
Does a watermark stop people from reusing my PDF?
Not necessarily. A watermark is only laid over the content, so editing software may be able to take it off, and the text underneath can still be copied and searched. To prevent changes, restrict them with Password protect PDF. If part of the document must not be read, delete it with Redact PDF.
What happens to a PDF with an electronic signature?
Saving invalidates the signature, because adding a watermark changes the file's content. To keep a signature valid, add the watermark before signing.
Help us improve the service
If a conversion fails, sending us the circumstances helps us track down the cause. Knowing which devices and formats fail most often, and how long processing takes, lets us revise the supported formats and fix the bugs behind them. If you don't mind, leaving this on is a real help.
