为什么要转换
Why convert WEBP to JPEG
02
Broader cross-platform support
JPEG is accepted by a wider range of image viewers, editors, and content systems than WEBP. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
Lower storage and bandwidth cost
JPEG files are typically smaller than their WEBP counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
