What is Add Watermark to PDF?
Add Watermark to PDF lets you overlay text on every page of a PDF document with full control over appearance and placement. You enter the watermark text (such as "DRAFT", "CONFIDENTIAL", or your company name) and choose font, font size, color, and opacity. Orientation can be horizontal or diagonal, with diagonal at 45 degrees being the most common for full-page overlays. Position options include center, top-left, top-right, bottom-left, bottom-right, and tile (repeat across the page). A repeat option can duplicate the watermark for denser coverage when you want to make screenshots or copies less useful. You can upload a local PDF from your device or fetch one from a URL. The watermarked PDF is generated on the server; you download it when done. Watermarks serve multiple purposes: they mark documents as draft, confidential, or copyrighted; they help deter unauthorized sharing by clearly identifying the document's status; and they keep the content readable while adding a visible label. Text watermarks are lightweight compared to image watermarks and do not significantly increase file size, making them ideal for documents that will be shared or stored.
The tool supports multiple fonts: Helvetica, Arial, Times, Courier, Georgia, Verdana, Palatino, and Garamond. These are standard fonts that render consistently across PDF viewers. Font size controls how prominent the watermark appears; larger sizes work for single full-page overlays while smaller sizes suit corner labels. Opacity controls how faint or bold the text appears; 0.2–0.4 is typical so the watermark is visible without obscuring the underlying content. Diagonal orientation is common for "DRAFT" or "CONFIDENTIAL" because it spans the page and is harder to crop out. Horizontal orientation works for headers or footers when you want the text to read normally. Position determines where the watermark appears: center is typical for full-page overlays that dominate the page; corner positions suit logos or small labels; tile repeats the text across the page in a grid pattern for maximum coverage.
Watermarks are a visual marker, not a security feature. They do not prevent copying, printing, or editing. Someone who receives the file can still extract content if they choose. The value of a watermark is in clearly identifying the document's status (draft, confidential, sample) and discouraging casual misuse. For stronger protection, combine watermarking with password protection using the Lock PDF tool. When preparing documents for distribution, adding a watermark is often a final step before sending. Test the result in your target PDF viewer to ensure the appearance meets your expectations; some viewers render transparency or overlapping text differently. Processing occurs on the server, so ensure you are comfortable uploading your files. The tool does not store documents; they are processed and the result is returned for download.

Tips & best practices
Use opacity around 0.2–0.4 so the watermark is visible but does not obscure content. Diagonal orientation is common for overlays. Center position works well for full-page marks. Test with a sample PDF to confirm appearance. Gray is often used for draft; red for confidential.
Limitations & notes
Text watermarks only; no image watermarks. Font availability depends on the server. Very long text may wrap or truncate. Some PDF viewers render transparency differently. Watermarks do not prevent copying; they are a visual marker. Processing occurs on the server.
