Size of this data
An Avro file carries its schema in the header ( here), so for a handful of records it can be larger than the JSON. The records themselves are binary and usually several times smaller; paste more data to see the difference grow.
Your data stays here
AvroConvert runs inside this page as WebAssembly. Schemas, files and messages are processed in your browser and never uploaded. Shared links keep their content after the #, which browsers do not send to servers.
