Frequently Asked Questions

Is angle adjustment supported for my Custom Document?

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 Document 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.

When should I tile my stamp on my Custom Document?

A tiled or grid watermark is the strongest possible protection for your Custom Document. 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 Document remains viewable while being 100% theft-proof.

Are hex codes supported for Custom Document?

Yes, full color customization is a standard feature in our Custom Document 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 Document's aesthetic.

What happens to file properties on my Custom Document?

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 Document. 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.

How can I avoid ugly stamps on my Custom Document?

Creating a professional-looking watermark is all about restraint and proper placement. The biggest mistake amateurs make is making the watermark overly aggressive and distracting. To look professional on your Custom Document, stick to elegant typography and monochrome graphics. Place it in the bottom right corner or along a natural line in the composition, and make it highly transparent. Adding a very subtle drop shadow ensures it remains readable on complex backgrounds without ruining the visual impact of your work.

How do I protect animations like my Custom Document?

Currently, our core engine is highly optimized for static images and documents. If you upload an animated file, the output will typically be a flattened, static image of your Custom Document. Processing multi-frame GIFs requires massive computational overhead that can crash standard web browsers. For all your non-animated needs, our tool is the fastest and most secure option available.
