Frequently Asked Questions

How do I watermark a PDF without making the text unreadable like my Custom PDF?

When watermarking text-heavy documents, keeping the content readable is just as important as protecting the file. When using a solid, high-opacity stamp, it will obscure the underlying paragraphs, which frustrates the recipient. We highly recommend using a very faint, semi-transparent gray color. Additionally, placing the watermark diagonally across the page ensures it covers maximum surface area while allowing the human eye to easily read the actual document text 'through' the watermark.

Can I watermark files without internet while processing Custom PDF?

Yes, due to our advanced architecture. Since we utilize client-side WebAssembly and Canvas technology, the actual processing does not require an active internet connection. Should you lose connection while batch processing a massive folder of Custom PDF images, the tool will continue to work flawlessly. Everything happens on your local machine, and the final ZIP download is generated directly on your hard drive, making this the most reliable and secure tool for off-grid or travel workflows.

How do I make diagonal text for my Custom PDF?

Yes, rotating your watermark is fully supported and highly recommended for document security. Within the settings panel, you will find a dedicated rotation slider that lets you set the exact degree of tilt. For Custom PDF PDFs and corporate documents, a corner-to-corner tilt is the industry standard for stamps like 'CONFIDENTIAL' or 'DRAFT'. For photography, a slight tilt can make the watermark harder for AI removal tools to process to your branding.

What is the grid pattern feature on my Custom PDF?

A tiled or grid watermark is the strongest possible protection for your Custom PDF. Instead of placing a single logo in the corner, the grid covers the whole file in a repeating pattern. This is essential for highly sensitive, unreleased documents because it makes it physically impossible for someone to crop the watermark out. Though it obscures the aesthetic slightly, you can lower the opacity to 5% ensures the Custom PDF remains viewable while being 100% theft-proof.

How do I match my brand colors for Custom PDF?

Yes, full color customization is a standard feature in our Custom PDF editor. We provide a comprehensive color picker that allows you to select any hue imaginable. If you have a specific corporate identity, you can directly input your exact HEX color code to guarantee a flawless match. We also recommend using the color picker to sample a complementary color from your image to make the watermark blend naturally rather than clashing with the Custom PDF's aesthetic.

Is my copyright metadata preserved on my Custom PDF?

Our watermarking engine is designed to be non-destructive, meaning it retains the hidden data embedded in your source files whenever possible based on browser capabilities. If you process a camera raw JPEG, crucial information like your camera settings, location, and existing copyright tags is not maliciously stripped out when the visual watermark is applied to the Custom PDF. However, for complete security, we recommend adding your copyright info to the metadata via your camera or Lightroom before uploading to create a dual-layered defense system.
