Watermark

Watermarking helps protect your intellectual property by making it harder for others to use your images without permission. It also serves as a branding tool, ensuring your name or logo is visible when images are shared online. Photographers, artists, and content creators commonly use watermarks.

The best position depends on your goal. Center watermarks are hardest to remove but may obscure the image. Corner watermarks are less intrusive but easier to crop out. Tiled watermarks cover the entire image and are the most protective. For portfolio images, a semi-transparent center or tiled watermark works best.

An opacity between 20-40% works well for most cases. Lower opacity (10-20%) keeps the image nearly undistorted while still visible. Higher opacity (40-60%) makes the watermark more prominent. For maximum protection, use higher opacity with tiled placement.

Simple watermarks in corners can be cropped out. Single-point watermarks can sometimes be removed with editing tools. Tiled watermarks across the entire image are much harder to remove. No watermark is 100% removal-proof, but they serve as a strong deterrent and prove ownership.

This tool uses the Canvas API to redraw the image with the watermark, then exports as PNG. The image quality remains high. The watermark is permanently embedded in the downloaded file — it cannot be separated from the image data.
