Watermark PDF

Upload your file, pick Text or Image Watermark, then set the wording or image, opacity, and position. Enter page numbers to limit the mark, or leave that field blank to cover every page. Click Add Watermark and download the result. The mark is drawn onto the page content, so it appears in any PDF viewer and when printed.

Yes. The tool runs entirely in your browser, so there is nothing to install and no account to create. Your PDF is processed on your own device rather than sent to a server. That keeps working copies of contracts, invoices, and internal files off the network while you add the mark and download the new version.

No. All processing happens client-side in your browser. The PDF is read, the watermark is drawn onto the pages, and a new file is written without any upload step. Because the document never travels over the network, there is no server copy to delete afterward. Closing the tab clears the file from memory.

Yes. Select Image Watermark and upload your picture, then set its opacity and position. The tool places the image over each selected page as a semi-transparent layer. This is how you add an image watermark to PDF pages for branding, a seal, or a signature graphic. The colors come from the image itself, so prepare it before uploading.

Use the page field to name the pages you want, for example "1, 3, 5-7". The tool marks only those pages and leaves the rest as they are. Leaving the field blank applies the watermark to every page. This lets you stamp a cover page or a single appendix without touching the body of the document.

Opacity sets how much of the page shows through the mark, from 0 to 100%, with 50% as the default. Lower values make the watermark more transparent, which keeps the underlying text readable. Higher values make it stand out but can obscure content. For status labels over dense text, values between 20% and 50% usually strike a good balance.

The mark is drawn into the page content, not stored as a separate deletable layer, so it is not a locked security feature. A determined person with editing tools could still work around it. Treat watermarking as a visible label, not access control. If you need to block opening or copying, use password protection instead.

A watermark is painted into the page content, so it prints and shows in every viewer as part of the page. A comment is an annotation stored separately from the page and can be hidden or toggled off. Use a watermark for a permanent visible label. Use the comment tool for review notes tied to specific spots.

Yes, for text watermarks. Font Size runs from 12 to 200 with a default of 48, and Text Color takes a hex value, defaulting to a medium gray (#808080). Larger sizes span more of the page, while the color choice controls contrast against your content. Image watermarks use the colors already in the uploaded picture instead.

You can choose Center, Top Left, Top Right, Bottom Left, or Bottom Right. Center works well for a large status stamp across the page. A corner position suits a logo or small reference code that should stay out of the way of the main text. The chosen position applies to every page you mark.

No. The tool writes a new PDF with the mark applied and leaves your uploaded file untouched. You download the watermarked copy while the source stays as it was on your device. If a mark looks wrong, adjust the settings and run it again on the original rather than on the marked output.
