There are many different ebook formats out there. From plain text documents over pdf and doc files to native ebook formats like lit, pub, fb2 or pdb files. Problem is most ebook readers do not support all formats, so that it may be necessary to convert unsupported formats before they can be copied to the ebook reader to be read on it.

One of the programs for that job is Hamster Soft's Free eBook Converter which supports more than 200 different formats according to the company website. Among the supported devices are Apple's iPad and iPhone, Amazon Kindle as well as Sony, Acer and Bq ebook readers.

The installation suggests to install another program from the same developer. You need to pay attention to the installation if you do not want the second program to be installed. Free eBook Converter downloads the installation files from the Internet during installation, keep that in mind when downloading the program.

The program itself has a minimalistic interface. Users can drag and drop compatible ebook documents into the program interfaceor use the Add Files button to use the file browser to load documents into the program interface.

All files are then displayed with a small thumbnail screenshot, their name, file size and file extension. Individual documents or all can be removed from the listing. A click on next loads the device and format selection screen that displays the available devices and formats that the selected documents can be converted to.

Devices are displayed at the top. A problem here is that it is not clear into which format they are converted to. The formats and platforms on the other hand show all the file extensions and formats the documents can be converted to. This is likely the better option if the device owner knows the supported ebook formats.

A click on the convert button runs the conversion and stores them automatically in the same directory as the source files. Hamster Free Ebook Converter displays options to open the source folder after the conversion or to return to the selection screen to add more files or convert the ebooks again into a different format.

The program did have some troubles converting pdf documents into txt files during tests. Not all contents of the pdf ebooks were accessible in the text document after the conversion.

Users who are looking for a free program to convert ebook and other document formats can download the Free Ebook Converter at the developer website. The program is compatible with 32-bit and 64-bit editions of the Windows operating system. The program requires the Microsoft .NET Framework 3.5 and an active Internet connection during installation.

    For more details of how Hamster is in violation of GPL v3, and is thus using the calibre source code without the agreement of its authors, see:

    Hamster is in violation of the GPL. They took calibre, put a new skin on it and released it without distributing the source code or attributing the original author.

    You are aware that this program is, more ore less, just a shiny frontend to the conversion engine of Kovid Goyal’s “calibre”, are you? Hamster say so on their own site.
