Megapixels to MB at TIFF LZW 8-bit

1 Image size = 3.2 File size · profile-dependent conversion · context: encoding/quality profile

Direct Answer

1 Image size equals 3.2 File size

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

For 2 Image size, this profile returns 6.4 File size.

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

Explanation

TIFF LZW 8-bit assumes 3200000 bytes per megapixel. MB = MP x (3200000 / 1,000,000). With input 1 MP, output is 3.2 MB.

For Image size to File size, the active encoding/quality profile determines the conversion constants applied to every value.

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.
