このツールとは？
This tool adds a text or image watermark on top of your image. You can add copyright text, a logo, or brand text to help protect or identify your images.
なぜ使う？
Useful for protecting images you publish on blogs, shops, or portfolios, or for batch-adding a logo. You can adjust position, size, opacity, and repeat pattern to fit your needs.
使い方
Upload the base image, then choose "Text" or "Image" for the watermark. For text, set the text, font size, color, and opacity; for an image, upload the file and set size, position, and rotation. Use "Download" to save the result.
You can set position (e.g. top-left, center, bottom-right), size, opacity, and diagonal repeat pattern. Watermarks cannot be removed after adding; keep a backup of the original.
