Explanation

PNG RGBA 8-bit assumes 2800000 bytes per megapixel. MP = MB x (1,000,000 / 2800000). With input 1 MB, output is 0.357142857143 MP.

File size to Image size is profile-bound here: the selected encoding/quality profile controls the mapping used by calculator and reference table.

Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: encoding/quality profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
