从谷歌下载了 WebP 文件，却发现 Word 文档、邮件客户端或公司应用都打不开？那就转换成 JPG 格式——所有软件都支持这种格式。
或者将图片拖放到这里。
支持JPG, JPEG, PNG, WEBP, SVG, GIF, HEIC, HEIF, BMP, TIFF, HDR, JP2, RAF, PSD, CR3, DNG, APNG, AVIF, AVI, ESP, EXR, J2C, J2K, JXL, PFM, PNM, PPM, PSB, SGI, MPEG, PDF
拖放从浏览器下载或从网站提取的 WebP 文件。转换器支持有损和无损 WebP 输入。
JPG格式没有Alpha通道，因此WebP图像中的透明区域会与白色背景合成。可见像素则变成标准的RGB JPG图像。
输出结果适用于任何接受 JPG 格式的设备——过去 30 年生产的所有操作系统、应用程序和设备。

Requires the WEBP delegate library. Specify the encoding options with the -defineoption See WebP Encoding Options for more details.
Joint Photographic Experts Group JFIF format
Note, JPG is a lossy compression. In addition, you cannot create black and white images with JPG nor can you save transparency. Requires jpegsrc.v8c.tar.gz. You can set quality scaling for luminance and chrominance separately (e.g. -quality 90,70). You can optionally define the DCT method, for example to specify the float method, use -define jpeg:dct-method=float. By default we compute optimal Huffman coding tables. Specify -define jpeg:optimize-coding=false to use the default Huffman tables. Two other options include -define jpeg:block-smoothing and -define jpeg:fancy-upsampling. Set the sampling factor with -define jpeg:sampling-factor. You can size the image with jpeg:size, for example -define jpeg:size=128x128. To restrict the maximum file size, use jpeg:extent, for example -define jpeg:extent=400KB. To define one or more custom quantization tables, use -define jpeg:q-table=filename. These values are multiplied by -quality argument divided by 100.0. To avoid reading a particular associated image profile, use -define profile:skip=name (e.g. profile:skip=ICC).
