Best Free Electronic Book Reader


There is a very thin line between an eBook-reader and a PDF-reader. While the PDF-reader just needs to read PDFs, an eBook-reader is expected to optimize the process of reading an eBook on your computer.

Desired characteristics are the ability to:

  • Read various formats including PDF, HTML, TXT and other formats
  • Organize books into categories for easy reference and to create favorite lists
  • Annotate, highlight and bookmark pages.

Choosing one best reader among the multitude available is both a tough task and also an insensible one. Once upon a time, the humble .txt format used to be the only form of data. Today, there are nearly unlimited formats. While in an ideal world one would prefer all of this data to be in an open format, the same cannot be expected in the real world. Our books are tied down in either .pdf or .lit or .pdb. So, one has to exercise discretion in selecting the best reader.

Among the various software discussed here, most aim to only present your book in an almost paperback-like format. Only a few try to organize them and add value to the same. Since the main purpose is to read books and not just text, preference is given to those that add value rather than just display your book in a fancy format.

Mobipocket Reader DesktopMobipocket Reader Desktop is a fully-featured reading solution. It has an intuitive interface, annotations and even a dictionary search when configured properly.

The reader includes an auto-column layout for an optimal reading experience, with options for page size, full width display, 2 or 3 column display with customizable font types, sizes and background colors.

It supports .lit,.html,.txt and .pdf files. Mobipocket also claims to sync with all your mobile devices such as a smartphone, Blackberry or PDA.

The main disadvantage is that it stores all of your books in a proprietary .prc version. What this means is that for every book you read, you need to import it into Mobipocket.


CalibreCalibre is open source eBook library management application. Calibre supports extensive file conversions, with the ability to convert over thirteen document formats into EPUB, PDF and MOBI formats for use on popular eBook-readers like the SONY PRS 500/505/700, Cybook Gen 3, Amazon Kindle (1 and 2) and the iPhone (with the stanza reader software).

You can also set up Calibre to fetch news from websites and RSS feeds and convert it into a compatible format, so you can load up your eBook-reader with information from your favorite sites. There's even a built-in web server so you can access your eBook collection remotely. It even has a cover-flow browsing feature for your books. However, it tries to sort all your books in its own preferred folder structure, so if you're a person who uses your own folder-hierarchy use this carefully.


Other eBook Reader Suggestions:

Tom's eTextReader reads rtf, html and txt files. Useful features are opening files directly from zip archives and a downloading tool for Project Gutenberg files. But the entire software is a little bit outdated. It lacks support for some commonly used formats. You can check this out at

yBook, is a beautiful piece of software whose main aim is to provide a 'paper book' experience on the computer screen. It even allows you to choose what color your pages are and provides a default two-page layout (which can be changed). It opens .txt, .pdb, .rtf and .htm files. This also has a Project Gutenberg downloader. If you want a simple reader that gives you a book like relaxed read then this is it. You can check this out at

"yReader2" hasn't been updated for a couple of years, "Reader Library" has been shut down for a year, and this site is falling further and further behind the curve. What did you do to your volunteer editors?

Thank you for pointing this out sonoffar. The obsolete entry has now been removed. In fact this category review is in need of an editor and maybe you would like to volunteer to take it over? If so please use the form at the link below. You can also contact me directly by clicking my username. MC - Site Manager.

Is this category still in need of an editor?

Yes it is Beggar. Please follow the link posted above if you are interested in taking it on. MC - Site Manager.

yBook2 has apparently not been updated since 2012. This particular TSA has not been updated for some time as well.

I'm not sure that Mobibook is still free. All the points on their website that looke like amy kind of download return a message that the resource has been removed.

Is available and working here:

[Moderator's note: Link to direct download of file not allowed. Replaced with the link to the software page]

If you are referring to MobiPocket, it is no longer available in any form. This was brought up here in the comments in 2012 (further down the page): "...MobiPocket was killed by Amazon in late 2011/early 2012. " There was no editor for this page at that time and apparently there has not been one since.

The final version (6.2) is available on various freeware sites, e.g. Softpedia, CNet, etc if you look around.

It's a very nice reader, it was my favourite for a long time. I only stopped using it because of problems making it portable (it requires Java Runtime installed) and because Calibre changed to offer a double-page "proper book" style of layout.

Ah that makes sense (the last version still being around). Just not available at the "official" site. Personally, I use Calibre and Sumatra. There is a portable Java available at PortableApps. I used to create a portable Java for Vuze, but have not done so in quite some time. My memory is that it was not that difficult.

I've had some luck with making Java-dependent software portable but I never got around to putting much effort into Mobipocket.

It was the lack of a double-page layout really that put me off Calibre before and it now has that and a whole lot more : ) It really is very good.

For anyone interested sumatrapdf viewer can handle .mobi files as well. I am satisfied.

Just took a look at yBook. It's now at version 2 and can handle ePub.

Here is a list of current features:

Runs on any Windows PC (Win95 or later)
Display your book on side-by-side or single pages.
Resize the pages, adjust the margins, set text and paper colour.
Text, html and RTF reader
PDB and PRC reader
ePub reader
Search for words or phrases
Automatic bookmarks
Text sizes from tiny to HUGE
No zooming, panning or scrolling
Direct download of all Gutenberg titles, with index.
Internationalised menus - Spanish, German, etc
Completely free to use: No registration, no adware, no spyware.

It's a kind request. Whenever you suggest a software, please post a link to its site. I have inserted the link this time in the comment. Also, if you notice, yBook has been suggested just a comment below.

A bit late but........ Not only is this the best allround software of its type I've found, but:
1. It's free!
2. Very Well-written
3. The author's Site (He writes SF and programs) has extra goodies there.
A great place for aspiring Authors, too.

Thanks Himagain, it certainly looks interesting. I will review it shortly.

Recently I have spent several days playing with different readers (for W7) and my recommendation would be like this:
- Universal all-in-one solution (for most formats): Calibre (Portable)
- "Single" format solutions: Adobe Digital Editions or Foxit Reader Classmate Edition for epub / Mobipocket Reader for mobi
- Lightweight and highly customizable (thus elegant) epub solution: EPUBReader for Firefox
