FAQ

What is VarInt Decode?

VarInt Decode decodes a VarInt encoded integer. VarInt is an efficient way of encoding variable length integers and is commonly used with Protobuf. It runs entirely in your browser, so your data stays private.

Is VarInt Decode free to use?

Yes. VarInt Decode is free, unlimited and works without registration or installation.

Does my data get uploaded?

No. All processing happens locally in your browser; nothing is sent to any server.

Good to know

  • Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
  • The worked example below could not be pre-computed for this tool (threw: function is not iterable (cannot read property Symbol(Symbol.iterator))); the interactive tool above still works normally.
