What happens when converting WEBM to AVI?
The WEBM data is decoded inside your browser with WebAssembly and re-encoded to the AVI specification, so no file is ever uploaded to a server. AVI uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process.
