Epub To Mobi
Rubi Strycker
EPUB is an electronic document viewer format that can display digital. EPUB uses an open format that uses XML format. Several eBook readers support EPUB files. In this format there different open standards are used. It can define content markup, structure and compress the content as ebook format.
MOBI is an eBook format that supports several eBook reading devices and gadgets. It also supports in mobile phones and PDAs. Although it is a file extension of Mobipocket Reader, most other eBook readers also support this file format. It also contains DRM to protect the digital right of the eBook. This format is officially discontinuing from the year 2011.
You can also do this without installing Calibre. This would be really handy on a Chromebook, for example. There is a free, online site called EPUB Converter that will let you upload the epub and it lets you then download the mobi equivalent.
I tried exporting from LaTeX to PDF, but isn't perfect because I have to zoom in-out and move around the page many times (isn't confortable like when you read a normal ebook purshased in book stores).I tried too exporting to RTF, but none of my mathematical formulas were in the output document.
Compile it with: htlatex myfile "html". Then load the resulting myfile.html in Sigil. Here I add missing metadata, split the chapters and mark the cover page image. Then save as epub and load it (via Calibre) on my reader.
The mobi versions can be larger because they include the legacy mobi format, the new KF8 format and a copy of the original epub, this is assuming the mobi file was generated with the latest version of kindlegen.
For the PDF's I'm guessing (and that's all it is here) that embedded fonts may be the cause of a larger file size, another thing that comes into play here is image optimisation. Depending on the image optimisation settings used when the PDF was created will largely affect the final file size.
Epub's are basically just a bunch HTML, CSS and image files with a few XML files for defining the books metadata, chapter order and table of contents navigation. The epub file is really just a zip file with a .epub extension and since it doesn't have 3 copies of the same book like the Kindle version does it will always be much smaller.
Because the epubs are similar to a website. An epub book is made from XHTML & CSS2 & some features like CSS3, then the software that reads epub interpret that file and make a visual representation from that code.
That depends on the format of the mobi that you have. As you must be already aware, an epub file can be converted into any ebook format that you choose - you can consider the epub format as the base for any other format.
I am guessing that the mobi file that you have has the original epub embedded inside it. This is to assist editing tools (as direct editing of mobi files is cumbersome). Also, some mobi files contain several versions of the mobi(mobi-7 and KF8) to maintain backward compatibility with readers that do not support the latest format.
I'm not talking about some nasty hack-ola baloney here... these are books I have paid for and not looking to break the drm, just allow mobi to know about the licensing... and formatted so mobi can read it.
If they aren't DRMd/secured mobi ebooks, Calibre will do the changeover, BUT... I do this for a living (MAKE ebooks and print books for publishers and self-publishers), and going from ePub to Mobi with Calibre will always give you better results than going the other direction. Not that you have that option, I understand. In fact, my process is to always make the ePub first and move from there to Mobi/PRC to get best results in end files. No offense, but if you want to convert something that is already in it's final Mobi state to something else, you're never going to come up with the kind of results I get making a file from scratch and going through the logical steps from one format to the epub or mobi books. I used Vibosoft mobi to epub converter: this is the guide how to convert mobi file to epub format.
PS : Does iPad NOT still have the Kindle reader available? Or an old Mobi reader like Adobe Digital Editions or the really old direct Mobi reader? It might be better to read the books on your new equipment in their native format than to play with conversion.
Yeah, i agree with the solutions above, and i'd like to share my way with you here! If you want to transfer your ePub format to MOBI, you can either try Calibre or iPubsoft ePub to MOBI Converter! And if you want to realise the opposite function, view this guide here which tells you how to convert MOBI files to ePub, which i think is also very useful:
Hello, I have a question for help here, I have a lot of .mobi books on my computer, I wanna transfer these mobi books to my iPhone and iPad for reading, but I found they doesn't accept mobi format, I tried many ways to convert mobi to ePub but failed, the quality of the output ePub file is so bad, unable to read. pleae help! Is there any software can convert hundreds of .mobi files to ePub format with high quality? Don't give me calibre, it keep crashed in my windows 8, and the it is not easy to use, waste of my time.
And, what did I say? Asnlinkda askedhow to convert a mobi book into an epub book(not how to convert an epub in a mobi). I said him that he should use some thid party app (that produces epub books) and if it's necessary, to polish the resulting book mobi to ePub converter. I also say that he could use mobi to ePub converter but that I prefer to use the first method. So, I say that is preferable to use (if it were necessary)
The way I go from Mobi > ePub is to use Vibosoft ePub creator or iStonsoft mobi to epub converter to convert, use Modify ePub to put in the cover and then use Sigil to rename the files and clean up the code/CSS. I find that's the easiest way to do it.
Some .mobi books -especially if they were generated with Kindlegen 2.x- have a .kf8 version AND an old .mobi version inside (all the more, files generated by the service of Kindle Direct Publishing, are .mobi files). When we use KindleUnpack to unpack that kind of files, then the KindleUnpack produces an .epub book -for the .kf8 part of the original mobi- and others files for the .mobi7 part. We must work in Sigil with the .epub generated from the .kf8 part. Of course, if the book is an old one (previous to .kf8/azw3) then things are more difficult. Still we can build an epub with the .html, .ncx and .opf generated by KindleUnpack and the epub will work in ADE but won't validate at Epubcheck. If we want to be more prolix, then as you say, we have to use a lot of regex to clean de .html and after that to write a css stylesheet, to convet mobi to epub, you have to try professional tool like: mobi to ePub converter.
I am guessing that you are running the calibre server on your computer. If you are leaving your computer on and trying to access it from your mobile, you can change the src value from the 127.0.0.1 or localhost one to your computer ip address. That should allow accessing the server from your other devices.
Thank you for your advice, but Its not working.
I think the problem is Android device Obsidian/electron do not allow HTTP connection
If i just put then it show cleartext not permitted.
if i put :password@IP then nothing show up, but i cannot scroll.
So i am trying to find out how to set my phone to allow http, or how calibre will use https now
Web browser on my phone can access the calibre content server, so i am guessing this is obsidian/electron security?
I understand that I need to read and mark up .mobi, .epub, kindle & apple books in their respective external apps, but I wondered if there is a way to import these files into Devonthink in order to have DT search the full texts of the documents alongside my PDFs and other documents.
DT is fine with DRM-free .epub files, but not .mobi or DRM-protected formats. But you can convert .mobi to .epub in Calibre, and DeDRM can strip DRM from older (pre-2023) Kindle books so that you can convert those too.
Hi,
I was wondering, if there is any chance that you could publish an ebook-version for the documentation (docs.julialang.org) which is automatically generated?
possible formats like: epub, pdf or mobi
This would be useful, because I could work offline from time to time. I know I could get just the source code on github. But maybe there is a more convenient way and possibly other people would like that, too.
It would be interesting to see how well that works. I am a big fan of e-readers for text with predominantly linear access (eg literature), but I find them cumbersome for everything else, including technical documentation. Also, I am wondering if the documentation requires a minimum screen width for tables and similar. YMMV.
Great alternative! Thank you for devdocs! Pretty cool website!
Offline feature is really the best part. Still I would prefer an extra file! Call me old fashioned, but I enjoy using a reader for such things, because I know where I find my stuff!
I Just finished a 72 page book with Affinity Publisher. Now I need to cover the book into epub but there is no option to do this in affinity Publisher. With most books having epub versions this is a critical feature to have.
