Welcome to the site! I'm Dan, and I'd be happy to help. I've been working with eReaders since their inception over a decade ago. Can you tell me what you've already tried? Also, would you be willing to share the file with me so I can see what we're working with?
Thanks for the additional information. I saved your .ppt as a .pdf, and used Calibre to exchange the .pdf for a .mobi file that is readable by Kindle. Is that what you did initially? It seems to work well on my end.
Beg your pardon... it was the .azw3 file that worked well, not the .mobi
Calibre is a moderately good (and free) file converter that moves various file formats to others, including back and forth from Kindle formats (.mobi, .azw, .azw3, etc.). I normally use .azw3 because it adapts to a pretty wide array of formats, styles, fonts, etc. which isn't the case for .mobi, .pdf, or the other compatible formats. Try Calibre and .azw3 format, and let me know how you make out. I'll be here if you need anything. No rush. -Dan
Hello, my name is Rusty. Try this file, does it look ok in Kindle? Right click here and select Save File As...
Touch the top of the screen when you have that file open. Touch the menu (the three horizontal lines on the right). Touch Landscape. Does that make it look better?
