1 Image size = 0.9 File size · profile-dependent conversion · context: encoding/quality profile

Direct Answer

1 Image size equals 0.9 File size

This result depends on the selected profile context: encoding/quality profile.

For 2 Image size, this profile returns 1.8 File size.

1 Image size (megapixels) =
0.9 File size (MB)

Explanation

JPEG 2000 visually lossless assumes 900000 bytes per megapixel. MB = MP x (900000 / 1,000,000). With input 1 MP, output is 0.9 MB.

Image size to File 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.
