Frequently Asked Questions

What is the best opacity for PDF documents like my Custom PDF?

For PDF security, keeping the content readable is the primary concern. When using a solid, high-opacity stamp, it will make the document impossible to read, which frustrates the recipient. The best practice is using a very faint, semi-transparent gray color. Furthermore, using a 45-degree angle ensures it covers maximum surface area while keeping the data perfectly clear.

Can I watermark files without internet while processing Custom PDF?

Incredibly, yes. Since we utilize client-side WebAssembly and Canvas technology, you don't need to be online once the page has loaded. Should you lose connection while editing your Custom PDF images, your progress will not be lost. Everything happens on your local machine, and the exports are saved locally, ensuring you are never interrupted by server outages.

How do I make diagonal text for my Custom PDF?

Absolutely, adjusting the angle is fully supported and crucial for professional styling. Within the settings panel, you will find a precision angle input that lets you set the exact degree of tilt. In legal and business contexts, a corner-to-corner tilt is the most effective layout for stamps like 'CONFIDENTIAL' or 'DRAFT'. When protecting images, a slight tilt can add a dynamic, artistic flair to your branding.

What is the grid pattern feature on my Custom PDF?

The repeating pattern feature is the strongest possible protection for your Custom PDF. Rather than one isolated stamp, the grid covers the whole file in a repeating pattern. This is highly recommended for highly sensitive, unreleased documents because it completely prevents malicious users from cloning the background over the stamp. Though it obscures the aesthetic slightly, making the tiles highly transparent provides an invisible shield against unauthorized use.

How do I match my brand colors for Custom PDF?

Absolutely, complete color control is a standard feature in our Custom PDF platform. We provide a comprehensive color picker that lets you dial in your exact brand colors. If you have a specific corporate identity, you can type in your precise RGB values to guarantee a flawless match. It is a good practice to experimenting with subtle grays to make the watermark blend naturally rather than looking harsh and amateurish.

Is my copyright metadata preserved on my Custom PDF?

We prioritize file integrity, meaning it retains the hidden data embedded in your source files during the export process. If you process a camera raw JPEG, the underlying metadata is not maliciously stripped out when the visual watermark is applied to the Custom PDF. Please note, for complete security, you should ensure your EXIF data is populated prior to visual stamping to protect your Custom PDF both visually and invisibly.
