Background

Interpretation and common distinctions.

Format & quality notes

  • Expect a large drop in file size versus 24-bit BMP.
  • Fine text and hard edges may show JPEG ringing; for those, consider PNG instead.
  • BMP variants that the browser cannot decode will fail to open—try exporting a standard 24-bit BMP first.
