Frequently Asked Questions

Why use a tiled watermark for ID documents or client design proofs?

A repeating diagonal tiled watermark covers the entire image surface, preventing someone from simply cropping out a corner copyright stamp.

Does adding a watermark reduce my image resolution?

No. The canvas renders at the exact native pixel width and height of your original uploaded image.
