There's a tool that claims to unpack mobis, but then you need different tool (MobiPocket) to attempt to re-pack the mobi, and that tool is dead and the site equally deceased. Nope - everyone and everything recommends Calibre (which is great), but when Calibre fails to do the thing you need, there are no other options. Looked for python and other CLI tools on github and elsewhere. Tried using Amazon's Kindle Previewer 3 tool hoping to 're-write' the mobi, but the tool doesn't have this feature - can only work with. Left the original asin as it was, AND also tried using the asin from the store it's sideloaded), the Kindle removes the cover and displays its standard cover to annoy readers who care about seeing nice covers (that would be 99% of all readers). mobi on people's devices, and if he notices that a. Bezos has taken time off from his party yacht to check every. Kindle contains the 'amazon-cover-bug' directory, so Calibre is doing 'its thing' to try to fix the covers, but it is not resolving the issue. mobi's to the Kindle (PPW 2018).Ĭovers initially appear on the Kindle, and a few seconds later are replaced with generic blank covers.

I am Using Calibre 5.22.1 and the Kindle Paperwhite 3 with latest software. But on Calibre they were higher resolution, and Calibre handled the image rescaling during sideload. All the covers there are low resolution (max of 500px).

Is there a way to fix it without converting the books again? I have noticed that Calibre added the covers of the working titles on a folder on my Kindle (amazon-cover-bug). It fixed the cover, but it screwed the layout. But I didn't want to convert again, because I don't want to risk losing all the work I put into the layout. I added the covers after the conversion (stupid). Some people said that when you convert the book, Calibre already makes the cover ready for Kindle by default. Made sure 'sharing content via Facebook' option was disabled. BTW, I thought about lowering the resolution of the cover, but some of the books that do display cover on Kindle have high resolution cover on Calibre. Lowered the dpi of some covers from 96dpi to 72dpi. Deleted the book from the Kindle and reloaded them. And some of the books that do show cover don't even have the asin number.

I like to choose the best looking cover designs, and I get the highest quality possible (within reason not some 5000px 300dpi monster). Then, last but not least, added the covers. Adjusted line height, paragraph spacing and indentation, headings, etc. Took my sweet time to make the conversion perfect. I have some epubs that I converted to azw3 to read on my Kindle. I am a bit of a control freak and like to have my library organized and looking pristine.
