Product challenge

How can files be converted across formats while preserving privacy and avoiding servers?

Approach

Design and engineering direction

Designs a local-first universal conversion workflow with format-specific validation and truthful capability matrices, beginning with Android before broader cross-platform release.

FlutterDartOffline-firstFile formats

Truthful file-format support

Universal conversion is an aspiration that must be broken into specific input/output pairs. Each pair needs an actual on-device engine, compatibility checks, progress feedback and output validation; a format name in a menu does not constitute working support.

Architecture and release focus

NGConverter prioritizes functioning local conversion engines and Android acceptance before expanding advertising or subscription mechanics. Cross-platform architecture is retained, while unsupported conversion claims are intentionally excluded.

Perspective

Current stage and learning

An in-progress engineering initiative; completeness and format support must be established by passing conversion tests, not assumed.
