Generation loss — quality may degrade
FLV 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 FLV file may contain FLV metadata metadata. WEBP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

About FLV to WEBP Conversion
FLV (introduced 2002) and WEBP (introduced 2010) are both video formats, but they differ in important ways. FLV (Flash Video) is a legacy streaming format — converting to MP4 is recommended for modern use. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG.
Full Name: FLV uses Flash Video, while WEBP uses WebP Image. Compression: FLV uses Lossy, while WEBP uses Lossy & Lossless. Transparency: FLV uses —, while WEBP uses Yes.
When you convert FLV to WEBP, the goal is to improve file compatibility across devices. FLV 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. Understanding these technical differences helps you choose the right format for your workflow.
Your FLV file is decoded and re-encoded as WEBP. The conversion involves 4 steps: (1) your flv file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in webp format with optimal settings, (4) the converted file is ready for download.
