AVS Document Converter 

Whether you need to convert Office documents into PDF, ODT, HTML, TXT, various e-book formats, and image files or vice versa, AVS Document Converter is probably one of the most straightforward free utilities suitable for the purpose. You can convert as many files as required to the output format selected in one single operation and customize the results by tweaking the basic format-specific settings provided.

This free document conversion tool has been clearly designed for users who require to convert a reasonable number of files between the most commonly used text and image formats without having to deal with the contents or the layout. The lack of editing or enhancing tools to prevent unwanted surprises in the output files is a clear declaration of intent – if you want to get acceptable results, make sure that the files you wish to convert have been properly formatted beforehand.

Together with the usual suspects (PDF, DOCX, RTF, TXT, HTML, etc.), this free document converter supports various e-book formats, namely EPUB, MOBI, and FB2. Converting between e-book formats generally produces good results, though the lack of layout settings (except for the possibility of preserving the original book cover and some embedded fonts for EPUB) may end up in certain formatting inconsistencies. As for PDF, you can add a watermark to your most sensitive documents and even protect them by adding owner and user passwords and prevent the user from performing certain actions.

Apart from the conversion process itself, the program comes with some additional features that are worth mentioning. Thus, you can rename files, merge two or more of your open documents, create ZIP archives, extract images from supported documents in JPG format, and send directly from here via e-mail any of the documents selected. For a free document conversion tool, AVS Document Converter is certainly a program worth trying, especially if the output you require is not subjected to too many specificities.
