为什么要把 WebP 转为 PNG？
WebP 很高效，但 PNG 在编辑、存档和兼容性上仍是更稳妥的选择。与转 JPG 不同，WebP 转 PNG 是无损的——每个像素都精确保留，包括透明背景。设计师在修图前会把 WebP 截图和图形转成 PNG，因为 PNG 在所有修图软件里都能用，而桌面软件对 WebP 的支持还参差不齐。
如何将 WebP 转为 PNG
1. Drop your WebP images into the box above, or click to choose files.
2. 点击转为 PNG。每张图片都会在浏览器中解码并无损重新编码。
3. Files download automatically — singles directly, batches as a ZIP.
Note: PNG files are larger than the WebP originals. That is the price of lossless quality and universal compatibility.
常见问题
Is WebP to PNG conversion lossless?
Yes. PNG stores every pixel exactly, so nothing is lost in the conversion. The trade-off is larger file sizes than the WebP originals.
Does PNG keep WebP transparency?
Yes. Both formats support an alpha channel, so transparent areas stay transparent.
Why is the PNG bigger than my WebP?
WebP uses more advanced compression. PNG prioritizes exactness and compatibility over file size, so expect 2–4x larger files.
Are my images uploaded anywhere?
No. Everything runs in your browser via the Canvas API.
Can I batch convert?
Yes — multiple files are bundled into one ZIP.
