Frequently Asked Questions

What is the grid pattern feature on my Custom PDF?

A tiled or grid watermark is the ultimate form of visual security for your Custom PDF. Instead of placing a single logo in the corner, tiling duplicates your watermark and spreads it across the entire canvas. This is essential when you are sending unpaid proofs to a client because it makes it physically impossible for someone to crop the watermark out. While it is visually aggressive, 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 available in our Custom PDF editor. You are not limited to basic black and white that allows you to select any hue imaginable. For strict brand guidelines, you can directly input your exact HEX color code to ensure perfect consistency. We also recommend using the color picker to sample a complementary color from your image to ensure it looks professional 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 preserves your original EXIF metadata whenever possible based on browser capabilities. When you upload a photograph, crucial information like your camera settings, location, and existing copyright tags remains intact when the visual watermark is applied to the Custom PDF. However, if you want the absolute highest level of legal protection, we recommend adding your copyright info to the metadata via your camera or Lightroom before uploading to create a dual-layered defense system.

What are the best practices for watermarking on my Custom PDF?

Creating a professional-looking watermark requires a balance of visibility and subtlety. The biggest mistake amateurs make is using a massive, 100% opaque, neon-colored font right in the middle of the image. To look professional on your Custom PDF, use a clean, minimalist sans-serif font or a high-quality transparent logo. Place it in the bottom right corner or along a natural line in the composition, and drop the opacity to between 15% and 25%. Adding a very subtle drop shadow ensures it remains readable on complex backgrounds while maintaining your artistic integrity.

Does this support moving images like my Custom PDF?

Currently, our core engine is highly optimized for static images and documents. While you can upload the first frame of a GIF, the output will typically be a flattened, static image of your Custom PDF. Watermarking every single frame of a complex animation requires massive computational overhead that can crash standard web browsers. For static Custom PDF files, however, our tool is the fastest and most secure option available.

Can I stamp public domain photos for Custom PDF?

You should only apply a copyright watermark to Custom PDF documents that you have personally created or hold the exclusive legal rights to. Slapping your watermark on stock photos, other people's artwork, or public domain images does not grant you legal ownership and can lead to severe legal consequences, including DMCA takedowns and lawsuits. However, if you are adding a transformative, educational, or parody watermark, different rules may apply. Always ensure you are the rightful copyright holder to stay legally compliant.
