About Add Watermark to Image / 关于本工具
A watermark is text laid over an image to mark ownership and discourage unauthorised reuse. Photographers stamp their name or website, businesses add a brand or "SAMPLE/CONFIDENTIAL" label, and creators tag work before posting it publicly. While a watermark can't make an image theft-proof, a visible mark across the content makes casual copying far less appealing and reminds viewers who made it. This tool lets you set the text, then control its size, position and transparency so it's readable without ruining the picture.
水印是覆盖在图片上的文字，用来标明归属、阻止未经授权的转用。摄影师会打上自己的名字或网址，企业加上品牌或"样张/机密"字样，创作者在公开发布前给作品署名。水印无法让图片绝对防盗，但横贯内容的可见标记会大大降低随手盗用的吸引力，也提醒观者作者是谁。本工具让你设定文字，再控制其大小、位置和透明度，做到清晰可见又不毁掉画面。
Make it hard to remove / 让它更难被去掉
A small logo tucked in a corner is easy to crop off. For real protection, use a semi-transparent watermark placed over the main subject, or repeat it across the whole image — annoying to erase without damaging the content. Keep opacity around 30–50% so the mark is clearly there but the photo still reads. Batch mode applies the same watermark to a whole set at once.
缩在角落的小 logo 很容易被裁掉。要真正保护，就用半透明水印压在主体上，或让它在整幅图上重复——想抹掉又不损伤内容会很麻烦。透明度保持在 30–50% 左右，让标记清晰存在又不挡住照片。批量模式可一次给整组图片打上相同水印。
