At this time, we specialize in high-speed processing for JPG, PNG, WEBP, and PDF formats. While you can upload the first frame of a GIF, it will render as a single watermarked frame of your Custom PDF. Watermarking every single frame of a complex animation is better suited for dedicated video editing software like Premiere or After Effects. For static Custom PDF files, however, we provide unmatched performance and privacy.
It is only legally appropriate to claim ownership of Custom PDF documents that you actually own. Slapping your watermark on stock photos, other people's artwork, or public domain images is a deceptive practice and can lead to severe legal consequences, including DMCA takedowns and lawsuits. That being said, if you are adding a transformative, educational, or parody watermark, it might be permissible. Protect your own original Custom PDF creations to stay legally compliant.
Getting the positioning right is essential. Our Custom PDF editor features a smart positioning system that allows you to freely move your watermark anywhere. For perfect precision, we include quick-snap alignment buttons that automatically calculate the perfect margins of the file. This ensures that if you are stamping a massive PDF, the layout never jumps around, maintaining strict brand uniformity.
Absolutely, it works universally on all operating systems. Because it is a progressive web application, your operating system is completely irrelevant. As long as you have a modern web browser, you can fully leverage our Custom PDF watermarking engine. You never have to worry about .exe or .dmg installers, no drivers to update, and no software conflicts. It is true plug-and-play security.
Scaling across different resolutions is critical. If you use absolute pixel sizing (e.g., exactly 300px wide), the stamp will appear disproportionate on different files. To solve this, our Custom PDF engine uses relative scaling. By defining the scale relative to the canvas, the system automatically adjusts the graphic for each individual document. This ensures your Custom PDF watermark maintains exact visual consistency across all resolutions.
We have optimized the export process for massive scale. When you finish processing a batch of Custom PDF images, our engine compiles everything into one convenient download folder. With just one click, you can retrieve your entire batch in seconds. This ZIP generation happens locally in your browser, ensuring zero wait times and maximum security. Just unzip the file and your protected documents are perfectly organized and ready to go.
