Frequently Asked Questions

How do I fix the white box around my logo on my Custom Document?

When you see a solid box instead of a transparent logo, it means the file you uploaded is likely a JPG. The JPEG format mathematically cannot hold an alpha channel, so any empty space is automatically filled with white. To achieve a seamless overlay on your Custom Document, you must ensure that your logo is a true transparent PNG or SVG. Once you upload a proper transparent PNG, our canvas editor will seamlessly overlay the graphic onto your Custom Document, removing the ugly white box entirely.

How large of a file can I upload for my Custom Document?

Thanks to our client-side architecture, there are virtually no strict file size limits on your Custom Document files. Unlike cloud-based tools that restrict you to 5MB or 10MB, our platform uses your local RAM and CPU to render the watermark. You are free to process heavy, professional-grade assets as long as your computer has the memory to handle it. If processing hundreds of huge files, ensure your system has available RAM to ensure a smooth export.

Is it possible to use multiple watermarks on my Custom Document?

Absolutely, using multiple elements is a highly recommended way to design a robust Custom Document watermark. While our primary interface focuses on streamlined single-element application, you can utilize creative workflows to layer your protection. Many professionals place their brand mark on the edge and a bold copyright text string across the center. Combining these methods provides maximum legal and visual protection for your creative Custom Document documents.

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

For PDF security, maintaining legibility is the primary concern. If your watermark is too dark, it will make the document impossible to read, which ruins the utility of the Custom Document. The best practice is setting the text opacity to around 10% to 20%. Furthermore, using a 45-degree angle prevents easy removal while keeping the data perfectly clear.

Can I watermark files without internet while processing Custom Document?

Incredibly, yes. Because the entire watermarking engine is loaded into your browser, you don't need to be online once the page has loaded. If your Wi-Fi drops while editing your Custom Document files, your progress will not be lost. Your files are processed using your local CPU, and the exports are saved locally, ensuring you are never interrupted by server outages.

How do I make diagonal text for my Custom Document?

Absolutely, adjusting the angle is a built-in feature and crucial for professional styling. In the editor controls, you will find a precision angle input that allows you to spin your text or logo a full 360 degrees. In legal and business contexts, a 45-degree diagonal rotation is the most effective layout for stamps like 'CONFIDENTIAL' or 'DRAFT'. When protecting images, a subtle angle can add a dynamic, artistic flair to your copyright notice.
