Sharing your original photography, digital art, or sensitive documents online always carries the risk of theft. The most effective way to prevent unauthorized use is to apply a tiled, diagonal watermark. Unlike a single small logo in the corner—which thieves can easily crop out—a tiled watermark covers the entire image, making it practically impossible to remove without destroying the photo itself.
1. Use Semi-Transparent Text: Keep opacity between 20% and 40%. It needs to be visible enough to deter theft, but transparent enough that viewers can still appreciate the underlying artwork. 2. Use the Diagonal Grid: The "Tiled" and "Diagonal" options are enabled by default in this tool because they provide the highest level of protection against cropping and AI removal tools. 3. Strip EXIF Data: Before publishing, ensure you also remove hidden GPS metadata to protect your physical location privacy.
