3 Free Document Converter Software Programs

Best Free Document Converters for PDF, DOCX, XLSX, TIF, WPS and More!

A document converter is a type of file converter that changes one kind of document file format, such as PDF, XLSX, DOCX, TIF, or TXT, into another type. If you're unable to open or edit a document because you don't have a program that supports it, free document converters can help.

Every document converter program listed below is freeware. We have not included any trialware or shareware document converters.

You can convert files that are as large as 50 MB.

Input Formats: CSV, DJVU, DOC, DOCX, EML, EPS, KEY, KEY.ZIP, MPP, MSG, NUMBERS, NUMBERS.ZIP, ODP, ODS, ODT, PAGES, PAGES.ZIP, PDF, PPS, PPSX, PPT, PPTX, PS, PUB, RTF, TXT, VSD, WKS, WPD, WPS, XLR, XLS, XLSX, and XPS

Zamzar also supports document to MP3 conversion, meaning it functions as an online text-to-speech tool. Several image formats are also supported as output options for many types of files, as is the SWF video format.

Not all output formats are available for all input formats. For example, you can't convert DOC to PUB.

Zamzar will work with any operating system that supports a web browser, such as all versions of Windows, Linux, and Mac OS X.

  • Registered users receive priority for conversions.

  • Requires an email address to receive converted files.

  • Converts only one file at a time.

FileZigZag is another online document converter service that will convert most common document, spreadsheet, and other similar formats.

FileZigZag also accepts several image formats as inputs and outputs but does not act as an OCR tool. There are also several input formats we listed above that do not export to every output format.

We like how simple it is to use FileZigZag, and top of that, it can convert large document files.

Much like Zamzar, FileZigZag can be used from any web browser on any operating system.

Doxillion

Doxillion document converter in Windows 7

What We Like

  • Multiple file conversions at once.

  • Windows and Mac software versions available.

What We Don't Like

  • Software install required.

  • Download links can be unclear and lead to downloading the "Plus" version that is not the free version.

Doxillion is another free document converter that supports popular file types. Unlike the two converters above, Doxillion is an actual program you have to install to your computer before you can convert any files.

You can add whole folders full of files or just choose specific files that you want to be converted.

Up to three right-click menus can be added to Windows Explorer. What this does is let you right-click a file and convert it quickly without having to first open the Doxillion program.

Input Formats: DOCX, DOC, HTML, HTM, MHT, MHTML, ODT, RTF, PAGES, EPUB, FB2, MOBI, PRC, EML, TXT, WPD, WP, WPS, PDF, CSV, JPEG/JPG, BMP, GIF, PCX, PNG, PNM, PSD, RAS, TGA, TIF, and WBMP

Output Formats: DOC, DOCX, HTML, ODT, PDF, RTF, TXT, and XML

On the download page, make sure you choose the download link called Download the free version here — it's off to the right side of the page. Any other download link may get you a trial of the version of Doxillion that isn't free.
