Generation loss — quality may degrade
JPG uses lossy compression and WEBP typically uses lossy mode. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your JPG file may contain IPTC metadata. WEBP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
