Image Watermark

Corner places a single watermark in one corner — easy to crop out. Tiled repeats the watermark diagonally across the entire image — far harder to remove without ruining the image, but more visually intrusive. Use corner for casual attribution; use tiled for serious protection of valuable photos or proofs.

Against casual reuse, yes. Against determined attackers, no — modern AI inpainting can remove watermarks from many images, especially corner ones. Tiled watermarks are much harder to remove cleanly. For real protection of high-value images, combine watermarking with low-resolution preview-only sharing of full images, content-ID systems, and DMCA enforcement.

30–50% is the sweet spot — visible but doesn't dominate the image. Below 20% and casual viewers may not notice; above 60% and the watermark distracts from the photo itself. For 'DRAFT' or 'CONFIDENTIAL' stamps where visibility matters more than aesthetics, 60–80% is appropriate.

For copyright: your name, business, or website (e.g., '© 2026 Jane Doe Photography' or 'janedoephotography.com'). For draft documents: 'DRAFT', 'CONFIDENTIAL', or 'NOT FOR RELEASE'. For preview-only proofs: 'PROOF — DO NOT USE'. Keep it short — long text becomes hard to read at typical opacity.

This tool focuses on text watermarks. For image-based watermarks (logo overlay, signature stamp), use Image Text Overlay or a more flexible image editor. The principles are the same: position, opacity, and either single-instance or tiled placement.

Slightly, due to JPEG re-encoding when you save. Save as PNG to avoid additional generational loss. The watermark itself is composited cleanly; the only loss comes from format compression. Keep the original unwatermarked file safe — once watermarked, it's hard to fully restore.
