Files with the FB2 extension (Fiction Book 2.0) are eBook files, supported by various reading devices. The format is based on XML, but unlike the EPUB format (which contains data in different files but a in a single ZIP package), its structure comprises of a single XML file.
AZW3 file contains digital publication saved in proprietary format Amazon Kindle Format 8. AZW3 files support array of formatting options for better device compatibility based on HTML5 and CSS3. AZW3 also supports DRM features. The format is backward-compatible with MOBI format containers.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the FB2 file after converting to AZW3 may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from FB2 to AZW3 to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting FB2 to AZW3 does not meet your expectations, you can simply try to find on the Internet a different version of your file in FB2 format, properly converted to a AZW3 file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file FB2 the desired result was not achieved, you can try to change the format of FB2 file to other than AZW3. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your FB2 file converted by someone else, and the attempt to convert it to AZW3 on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the FB2 file in its original format (without conversion to AZW3 file). Such a solution will be difficult to implement, but it certainly will give the best result.
