Update link KindleGen -> KindlePreviewer

I don't think this is a clear win. Yes Amazon no longer supports kindlegen, but their replacement for it is not a drop in replacement. The new "Kindle Previewer" es not have the CLI features of kindlegen and it is not even available for Linux. The last released version of the original kindlegen may not be endorsed by Amazon but it is available through various package managers and the internet archive. It is more suited for use in many workflows that would involve Pandoc.

If any change is made it should mention both apps with a note that the new one is GUI and Win/Mac only, the deprecated one is CLI and available for Win/Mac/Linux.

@alerque if we do that we should say something about how one can find the cli kindlegen.

Dropping of Linux support is unfortunate. Versions of KindleGen can be found at

• Linux https://archive.org/details/kindlegen
• Mac OSX https://web.archive.org/web/20190905040839/https://www.amazon.com/gp/feature.html?ie=UTF8&docId=1000765211
• Windows https://archive.org/details/kindlegen_win32_v2_9
  If these are mentioned, they will become outdated (Mac OSX is 32 bit only, and will only work on Intel based Macs), and if one chooses a random link, one may install malware.

Some workflows are moving to Calibre, for example

Amazon recommends Pandoc.

Here is a better link to the Linux kindlegen package: https://archive.org/details/kindlegen2.9

The archive.org link you posted is similar, but it was repackaged by somebody and doesn't have all the original files. This is the same gzip file originally posted by Amazon as can be verified by checksums. There are several others floating around out there that claim to be newer versions or reposts that have been tampered with, so verifying the checksums is actually important rather than just running some binary you found on the net!

Ok, added links.
