What is the total file size of this?

  It’s roughly 5000 x 5000 km, so 250 gigapixels. With 24-bit color, that would be about 700 GB uncompressed. Lossless compression can probably reduce that by a factor of ten or more.

    Which lossless compression would compress images like this by a factor of ten or more? Isn't lossless image compression ratio more like around 2:1?
    • layer8 3y ago
      It’s just a rough guess based on the redundancy in that image (limited range of colors, no hard edges). Lossless compression ratios can vary wildly depending on image contents.

        What we are really getting at here is: where's the jpg!?
