API, OpenAPI and WebMCP documentation

Explanation

JPEG web quality 90 assumes 420000 bytes per megapixel. MB = MP x (420000 / 1,000,000). With input 1 MP, output is 0.42 MB.

Method & Image Profile

Method basis: fixed bytes-per-megapixel estimate for the selected format and compression profile.
Profile reference: JPEG web quality 90 Image Files (420,000 bytes/MP estimate).
Consistency rule: snapshot, calculator, and common-value rows all use the same fixed image profile and bytes-per-megapixel estimate for this route.
