Whether you need a simple text stamp or a full tiled overlay, our Custom Document watermark engine does it all.
Before delivering final deliverables, always use a watermark. Overlaying a 'PROOF' or 'DRAFT' Custom Document watermark signals unapproved status. Creating these protected files is fast and effortless.

No, not at all. Our Custom Document watermarking system is specifically engineered to preserve the maximum resolution of your files. By applying a stamp, the tool only alters the pixels where the watermark is placed, leaving the rest of the image completely untouched. Whether you are uploading a massive 4K photograph, the downloaded Custom Document will keep its crisp detail, just with your added protection. We guarantee professional-grade outputs every single time.
Choosing between a typographical or graphical watermark is a matter of your specific needs. A custom text stamp is perfect for quick protection; you can quickly generate your name, copyright year, or a 'CONFIDENTIAL' warning and adjust the typography. Conversely, a logo watermark provides a visually striking aesthetic. If you are a business or professional photographer, uploading a transparent PNG logo helps establish authority on your Custom Document. Our tool allows you to use either, or even both simultaneously.
Yes, absolutely. Adjusting the alpha channel is essential for designing an effective Custom Document watermark. Our editor includes a precision transparency control that allows you to adjust exactly how visible or subtle your logo appears. For most photography and portfolios, setting the opacity between 15% and 30% is perfect, as it protects the file without distracting the viewer of the Custom Document. You can easily preview these adjustments in milliseconds, so you can find the exact right look.
To maximize security, positioning is absolutely critical. The most common mistake is putting the logo in the extreme corners of the Custom Document, which thieves can slice off in seconds. Instead, anchor your stamp across a detailed area of the image. For ultimate protection, use our 'Tile' or 'Grid' feature, which covers the entire Custom Document with a subtle, repeating watermark. This makes it mathematically impossible for AI tools to crop or clone out your branding without completely destroying the file.
Yes, our tool is 100% free. Competing Custom Document watermarking websites that force you to pay for high-resolution exports, we offer our full premium feature set for free. You do not need to enter a credit card, no registration is required, and we never apply our own forced watermarks. Our goal is to provide a professional-grade Custom Document security tool that is accessible to everyone, whether you are watermarking one file or one thousand.
Our versatile watermarking platform supports a wide variety of file formats for maximum flexibility. For images and photography, you can easily upload and process standard web image formats files. For corporate and legal use, our Custom Document tool also fully supports PDF documents. When you export, the system intelligently maintains your original file format, ensuring that a transparent PNG remains transparent. This broad compatibility makes it the ultimate unified tool for all your watermarking needs.
