PROTO format guide

A .proto file is protocol Buffers schema companion used to interpret a matching binary message; schemas are documented but never executed or fetched remotely. This release documents the format but does not expose a converter until its browser engine passes the fixture gate.

Current availability

Format information only

Novus Convert does not currently process this format. No upload or download control is shown because the site never represents an unavailable conversion as working.

Where PROTO comes from

Protocol Buffers schema files using the .proto extension belong to the data ecosystem and remain in use where their particular interchange or storage model is required. Browser support varies, so this profile distinguishes a tested local engine from reference-only coverage.

How PROTO works

  • The public file extension is .proto.
  • The format is classified as data data.
  • Recognized signatures include syntax = "proto.
  • No conversion route is published until output can be independently validated.

When to use PROTO

  • Opening or exchanging Protocol Buffers schema files without sending them to a remote converter.
  • Moving compatible content from .proto into a more broadly supported target.
  • Inspecting format capabilities and expected fidelity before conversion.

Strengths and limitations

Strengths

  • Can be handled without uploading private source data when a local engine is available.
  • Registry-backed routes expose only outputs with a concrete encoder.
  • Format and size validation catches common extension mismatches early.

Limitations

  • Some format-specific metadata cannot be represented by every target.
  • Large or unusually complex files can exceed browser memory limits.
  • Linked resources must be included in the selected folder or ZIP; remote references are blocked.

Compatibility

Protocol Buffers schema compatibility depends on the producing application and the format revision. Novus Convert's guide remains reference-only until the browser implementation is verified.

Metadata preservation is target-dependent and may be partial; the converter reports normalization or loss where applicable.
