Free File Converter Software and Online Services

Free Video Converters, Audio Converters, Image Converters and More

Sometimes you find yourself with a file in a format that no program on your computer supports. When this happens you usually have two options.

You can either purchase the program that opens the file or you can use free file converter software to convert the file to a format that some program on your computer actually does support. It's a common problem, especially among movie, music, and photo/graphics files.

Below are links to the best free video converters (like MP4 and AVI), audio converters (MP3, WAV, etc.), image converters (e.g. PSD and PNG), and document converters (PDF, DOCX, etc.):

Tip: See Other Converters at the bottom of the page for free file converter software for other types of files like ISO, IMG, and RAR files.
