About Crop Image / 关于本工具
Cropping removes the parts of an image you don't want, keeping only a selected rectangle. It's the simplest, most useful edit there is: straighten a tilted shot by trimming edges, cut out distracting background, focus attention on the subject, or remove sensitive information at the margins of a screenshot. Because you're discarding pixels, cropping also reduces the file size — sometimes a lot, if you only keep a small region.
裁剪去掉图片中你不想要的部分，只保留选中的矩形区域。它是最简单也最实用的编辑：通过修边让歪斜的画面端正、剪掉干扰的背景、把注意力聚焦到主体，或抹去截图边缘的敏感信息。由于你丢弃了像素，裁剪同时也会减小文件体积——若只留一小块，减幅会很可观。
Crop with the end in mind / 带着目标去裁
If the image is headed for a specific place — a profile photo, a banner, a product thumbnail — know the shape it needs first. For fixed shapes like a circle avatar or a 16:9 banner, the aspect-crop tool locks the ratio for you. For freeform trimming, this tool gives you a fully adjustable selection box. Cropping is non-destructive here: your original file on disk is untouched.
如果图片有明确去向——头像、横幅、商品缩略图——先弄清它需要的形状。对圆形头像或 16:9 横幅这类固定形状，比例裁剪工具会替你锁定比例。需要自由修边时，本工具提供可任意调整的选框。这里的裁剪不破坏原文件：你磁盘上的原图丝毫不动。
