在浏览器里做透明 PNG
透明 PNG 是 logo、产品抠图、贴纸和叠加图背后的格式。在本地做,源图就不会离开你的电脑——素材来自客户或还没发布的产品时,这一点尤其重要。
做一张边缘干净的抠图
- 1
从最大的源图开始
透明不会带来细节。用最大的原图来抠,显示尺寸下边缘才够锐利。
- 2
看边缘,不看中间
白边和残留背景只在轮廓、以及发丝、带子这类细部露出来。
- 3
导出 PNG,不要 JPEG
JPEG 没有 alpha 通道,透明图存成 JPEG 会带上一块背景。
透明 PNG 常见问题
- 为什么我的透明没了?
- 文件存成了 JPEG,它没有 alpha 通道。重新导出为 PNG 或 WebP。
- 会上传到哪吗?
- 不会。像素处理在你的浏览器里完成,所以对客户素材是安全的。
- 要消耗积分吗?
- 不用。本站的本地图像工具完全免费,也不消耗积分。
