在线为图片添加水印 - 免费添加文字或标志
为 JPG、PNG、WEBP 和 AVIF 图片添加文字或标志水印，并预览位置、平铺、旋转、大小和透明度。
Can I add a logo watermark?
Yes. Choose text or logo, then adjust placement, size, opacity, rotation, contrast, and single or tiled coverage before export.
Will Media Tools add its own watermark?
No. The exported image includes only the watermark you create.
Which image formats are supported?
The image toolkit accepts common browser-compatible images and exports JPG, PNG, WEBP, or AVIF.
Can a watermark completely prevent copying?
No. A visible watermark discourages casual reuse and preserves attribution, but it cannot stop every screenshot, crop, or manual edit.
