About Avatar & Aspect-Ratio Crop / 关于本工具
Profile pictures and banners almost always need a specific shape. A square 1:1 crop is what most platforms expect for an avatar; a circle mask gives you a ready-to-use round profile photo with a transparent corner; 16:9 suits video thumbnails and cover banners. Cropping by eye to these shapes is fiddly — this tool locks the ratio so your selection stays perfectly square or wide while you just choose what's inside it.
头像和横幅几乎总需要特定形状。正方形 1:1 裁剪是多数平台对头像的期望；圆形遮罩能直接给你一张可用的圆形头像，四角透明；16:9 则适合视频缩略图和封面横幅。靠肉眼裁成这些形状很费劲——本工具锁定比例，让你的选框始终保持完美的正方或宽幅，你只需决定框里放什么。

For an avatar, center the face slightly above the middle and leave a little breathing room — faces cramped to the edge look awkward once a platform rounds the corners. Circle avatars export as PNG to preserve the transparent corners; square and 16:9 crops can be saved as JPG and compressed afterwards if you need a smaller file.
做头像时，把脸放在略高于中线的位置并留一点余白——脸贴边的头像在平台把四角磨圆后会显得别扭。圆形头像以 PNG 导出以保留透明四角；正方和 16:9 裁剪可存为 JPG，需要更小文件时再压缩。
