How to Use Format Hubs
Each hub consolidates sample files, MIME signals, and machine-readable manifest links for one format/category pair.
Use hubs as stable references in QA playbooks, upload validation tests, and file-type regression checks.
FAQ
Coverage stats, MIME values, direct links to sample pages, and related format comparisons.
Yes. Each hub links to manifest JSON endpoints designed for reproducible CI or regression workflows.
New formats and fixture sizes are added continuously as testing demand grows.
