关于这个工具:免费社交图片尺寸转换器
Resize and crop images locally for social media formats such as Open Graph, square posts, stories, and thumbnails. 无需上传——全部处理都在你的浏览器本地完成,兼顾隐私与速度。
常见用法
- 网站预览和发布卡片优先用 Open Graph 尺寸。
- 想铺满画面用裁剪;必须保留完整图片时用完整留边。
按每个平台裁出合适的尺寸
每个平台裁同一张图的规则都不一样,而一个裁掉主体的预览比没有预览更糟。请按目标尺寸分别裁,而不是把裁切位置交给平台临时决定。
一张图,多个裁切
- 1
按「中心安全区」来构图
假设每个平台都会往中间裁。把主体和文字都放在居中的方形区域内。
- 2
每个尺寸都从原图生成
从母版缩放,不要拿已经裁过一版的图再裁,否则第二次裁切会把第一次的损失叠上去。
- 3
检查最小的那个尺寸
最小尺寸下文字读不出来,就去掉文字,让图自己说话。
社交图片尺寸常见问题
- 为什么我的链接预览看着不对?
- 平台按自己的比例裁了。请直接提供一张已经按该比例中心构图好的图。
- 每个平台都传最大尺寸行不行?
- 不行。过大的图平台照样会缩,同时还会拖慢你自己页面的加载。
- 缩放是在本地吗?
- 是,而且完全不消耗积分:整个处理都在你的浏览器本地完成,文件不会上传。
