Don't judge a book by its file format - convert it!

There are various e-book file formats and some of them are made just for a specific type of device or operating system. For example, EPUB extension is compatible with any iPod, iPhone, or Mac device. All of the mentioned have one more thing in common, and that's IBA. But this one is slightly less compatible with different e-readers.

On the other hand, MOBI, AZW, and AZW3 are the most used ones from Amazon. All these files are quite similar, but they are not fully compatible with all devices. Next, we have one of the most used formats worldwide - PDF. The only downside of this well-known type of file is the lack of reflowing. In case you're wondering, reflowing is a file ability to adapt its presentation according to the size of a screen.

There's also a TXT file format. This type of extension is an ASCII text-formatted data used for storing plain text files. TXT can be used for data that contains different formats, letter colors, text sizes, backgrounds, etc. Digital magazines use formats such as FLASH and HTML. It allows them to easily create content because of its cross-platform compatibility. Another plus is their ability to provide multimedia support and hyperlink content to different internal and external sources.

We're done mentioning the most famous ones, but there are a few less-common formats you can also bump into. First, there are LRS, LRF and LRX, formats created by Sony. The same company abandoned them in favor of EPUB, but they can still be found and used in some cases. Then, we have FB2. This format is mostly used among e-book collectors because it has the ability to metadata within the e-book itself. How cool is that?

Some file formats are absolute favorites in specific branches, such as science. We're talking about DJVU, of course. This is no surprise because DJVU format can store more than 100 black and white scans in less than a megabyte. Plus, it has a compression 10 times better than PDF.

One more file format is worth mentioning, and that's the Rich Text Format known as RFT. It has an advantage over the standard TXT because of its ability to retain special characters. Also, it supports reflowing and text formatting. Not bad, do you agree?

At the end of a day, and regardless of the format, you can convert any e-book file using our free online converter specially made for this type of documents. So, if you're not comfortable with one specific type of format, do a little file conversion, and that's it.

The most popular formats

As we previously mentioned, the most popular formats used are EPUB, MOBI, AZW, AZW3, and good old PDF. For most of the e-readers, these extensions are usable. But in case they are not, you can always convert them to some other equally "famous" e-book format. The real truth is - you only need to worry about EPUB, MOBI, and AZW file formats.

Why? The answer is simple. If you want to build a sizeable e-book library on your PC, compatible with most e-readers, stick with EPUB. On the other hand, if you want to create a collection of Kindle-specific books, choose MOBI. Or you can save files with the AWZ extension in that case as well.

Why should you choose e-book instead of printed ones?

Some people love the smell of books, and some prefer the touch of a paper on their fingertips. But, for all those indecisive, here are some main reasons why you should choose an e-book over printed ones.

1. Accessibility

E-books can be downloaded and stored on various devices. That makes them accessible anytime and anywhere.

2. All books on one device

It's far harder for you to carry 10+ books around than to store them on your laptop, PC, or phone.

3. We're all heard that caring is sharing

You can share a printed book with one of your friends at a time. On the other hand, an e-book can be shared with many people at once.

4.Easy to read

Any e-reader comes with different features where you can adjust the brightness of the screen or size of your text. You must admit that those adjustments are extra points in favor of e-books.

5. Listen to your e-books

You don't have time to read? No problem, there is a "Read at loud" feature. This means you can listen to your favorite chapters while you're doing chores around the house. If you haven't tried reading e-books yet, give it a try. You might be surprised how appealing and relaxing they can be.
