Can I tile the watermark across the entire image?

Yes. Enable the tiled repeat option and the watermark will be stamped in a grid pattern across the whole image. Tiling is the most theft-resistant approach because the watermark cannot be cropped away from any section of the photo.

Is it safe to watermark personal or professional photos here?

Yes. Everything runs in your browser using the Canvas API. Your photos are never uploaded to any server, so you can safely watermark private, proprietary, or client-facing photos without any privacy risk.
