How should I use the ICO manifest endpoint?

Fetch manifest JSON to pin fixture names, sizes, hashes, and MIME expectations in automated tests.

Why does this format have a category-specific hub?

A category-specific hub keeps assumptions aligned with practical workflows and related format alternatives.

ICO Format Hub

ICO (.ico) files store multiple icon images at various sizes and color depths in a single container for desktop and web favicons. Use sample .ico files to test icon parsers, size selection, and transparency masks.

Implementation Notes

Use the manifest endpoint for deterministic fixture selection in CI, then validate MIME/type detection against actual parser output.

If this format appears in multiple categories, prefer category-specific hub pages to keep test assumptions aligned with real usage.
