WebP 转 PNG 转换器
将 WebP 图像转换为无损 PNG 格式。非常适合在 Photoshop 中编辑、保留透明度或在不进一步损失质量的情况下归档图像。免费且私密。
何时需要将 WebP 转为 PNG？
虽然 WebP 是网页传输的最佳格式，但 PNG 更适合编辑、归档以及与专业软件的兼容性。当你需要在 Photoshop 中编辑图像、在不支持 WebP 的软件中打开，或在不产生额外质量损失的情况下保留每个像素时，转换为 PNG 是正确的选择。
PNG 作为无损主格式
PNG 使用无损压缩——意味着每个像素都被精确存储，保存或重新保存时无质量损失。这使其成为需要多次编辑和重新导出的图形的首选“主”格式。将 WebP 转为 PNG 可创建无损副本，安全多次编辑。
文件大小：PNG 通常更大
PNG 文件通常比同等视觉质量的 WebP 大 26–70%。将 WebP 转为 PNG 总会增加文件大小，因为 PNG 的无损压缩在大多数图像类型上不如 WebP 高效。当编辑质量优先于文件大小时，这种权衡是可以接受的。
常见问题
The conversion produces a lossless PNG output, but if the source WebP was encoded with lossy compression, that quality loss is already baked in and cannot be reversed. The PNG will be a pixel-perfect lossless copy of what the WebP contained - it won't recover detail that was discarded when the WebP was first encoded.
PNG is universally supported by professional editing software - Photoshop, GIMP, Illustrator, Affinity Photo, and virtually every image editor. WebP support in desktop editing software improved but is still inconsistent, especially in older versions. PNG also allows repeated saves without accumulating quality loss.
Yes. Both WebP and PNG support alpha channel transparency. If your WebP has transparent areas, they will be preserved exactly in the output PNG.
Significantly larger - typically 30–70%. A 200 KB WebP might become a 350–600 KB PNG. This is the expected trade-off when going from a compressed format to a lossless one.
