MOBI size, uploading to Amazon
Hi, dear all,
I send a 4M MOBI to my client. But she said as below" "Can you please reconvert the attached title for mobi? The previous converted file was fine, but it was too large for uploading to Amazon" So I want to know: What is the top size for a mobi if it can be uploaded to Amazon? |

So far as I know, there isn't a maximum size. However, there are (if the following is up to date) file size limits for some price ranges, from Enter or Change Royalty Option and List Price:

pdurrant (or anyone else), do you know the difference between the -C2 (Kindle huffdic compression) command-line option in KindleGen versus the -C1 (standard DOC compression) option?
I've tried both, and the -C2 produces a slightly smaller file than -C1. I can't tell any difference in the quality of the two .mobi files produced, as far as how they look on the Kindle. Just curious what the differences may be, without getting too technical. |

I'd always use the huddfic compression for a file I'm uploading to Amazon. But while I'm tweaking a book and testing it, I always use -c0 (no compression), as it's so much quicker to compile the book. |

Thanks for your helpful reply! The book does have four graphics, so that may explain why -C2 doesn't reduce the .mobi file size all that much (from 977KB using C1 to 910KB using C2).
When I email the .mobi file to Amazon for conversion, the .azw file comes back to me at 464KB. I'm guessing that's because the source files were stripped from the .mobi, but I don't really know. Thanks again! |

Thanks for mentioning the 127KB limit on graphics, but I had already checked to make sure they're within the limits. The cover is 127KB, and the four graphics are 63KB, 97KB, 60KB, and 51KB. I had forgotten, but there's also another graphic used throughout the book (43 times), and that one's 24KB.

And yes, it does seem that Amazon must be stripping off the source files for you. Interesting. I might have to experiment with that. |

The .mobi file that I sent to Amazon for conversion (via Kindle email) was compiled by me with no options on the KindleGen command line. I assume that's actually the -c1 (standard DOC compression) option because I tried -c1 later and it created the same-sized .mobi file as with no option specified.
The .mobi file I sent Amazon was 977KB and it came back in .azw format at 464KB. Happy experimenting! |
