Device Guide to E-book formats
So you have bought your first ebook, or you are considering making your first purchase, but you are not sure how to read the actual ebook once you’ve got it? Look no further, we will discuss your options here.
Firstly, it doesn’t matter which format your E-book is available in, you should be able to read it on the vast majority of devices available today. There are of course some exceptions which will be discussed below.
So if you are downloading in EPUB or PDF, most devices will accept both formats. But please note that crimsoncodex.com uses its own DRM software to protect most ebook files, so the device or the software running on the device must be compatible with DRM(most devices are). If you’d prefer to obtain your books without DRM, you can browse our DRM-free section.
But if your device is not compatible, don’t worry, even if you are unable to download the ebook in PDF, MOBI or EPUB format, if the ebook is also available in our Online Reader format then as long as your device has a web browser you should be able to read your ebook online.
Also, you may have multiple devices available to you with which to read your ebook. Which is the best one to use? We will cover some advantages and disadvantages or each kind of device.
Desktops & Laptops
All desktop and laptop PCs running Windows and Macs are able to read your ebook using the free Adobe Digital Editions (ADE) software. As long as your computer meets the minimum system requirements. But even if your computer is old, you can download an older version of ADE that should run on your machine.
The advantages of reading on a desktop or laptop are that you get a large screen to display the book, making reading easier and more relaxed.
There is no ADE version for Linux, but some users have reported having some success running the Windows version of ADE through Wine.
There is an exception to ‘all Windows PCs’ being compatible. Devices running Windows RT are not compatible. This is because this version of Windows is not a full version of Windows and will not run normal Windows applications, instead, it runs apps from the Microsoft app store, and there are currently no apps available that support Adobe DRM. As Windows RT was only on the Surface and Surface 2, if you have a newer Surface (Surface 3 onwards) it will be compatible as it runs a full version of Windows.
Similarly, Chrome OS devices are not compatible as there is no Chrome OS app version of Adobe Digital Editions, and older Chrome OS devices cannot run Android apps (although newer ones can). So if your Chrome OS device is running Chrome OS version 53 or higher and you have access to the Google Play Store you can install our Ebook Reader app. If your Chrome OS device is older I am afraid it is not compatible.
Tablets & phones
All recent tablets and phones using the Android, iOS, or BlackBerry10 operating systems (including Kindle Fire) are able to read your ebook using any free Ebook Reader app. If your device is more than a few years old and has not had an OS update in a while it may be that it is no longer compatible.
The advantage of reading on a mobile device is that you can read your ebook absolutely anywhere, you aren’t only confined to a desk. Also, most people already own a mobile phone or tablet so they do not need to spend extra purchasing a dedicated ebook reader device. The disadvantage is that the screen is smaller and it can be harder to read when compared to a nice big computer monitor.
Dedicated ebook reader devices
There are thousands of dedicated ebook reader devices, so it is impossible to cover them all here. The important thing to note is if your device is compatible with Adobe Digital Editions / Adobe DRM.
If your device supports it there should be a mention of “supports Adobe DRM” in its list of supported formats. That guarantees you’ll be able to download your ebook.
If your ebook reader just lists PDF and EPUB as supported formats, chances are it is not compatible with our ebooks. But you never can tell, as sometimes the manufacturers don’t bother to specify. All the bigger manufacturers like Kobo, Nook, and Sony Reader are supported. The exception is Kindle, which does not support Adobe DRM, but Kindle Fire devices are compatible as they have an Android-based operating system.
The advantage of a dedicated ebook reader device is that they tend to have far better battery life than today’s phones and tablets, and if you do have a mobile device you can still read your ebook on your ebook reader, leaving your mobile device free for other functionality.
With some newer devices, you can download the ebook directly to the device, but with most devices, you need to download the ebook to Adobe Digital Editions (ADE) on your computer, and then connect your device via a cable and transfer the ebook across to your ebook reader.
