5 Free File Converter Software and Online Services

Converters for video, audio, images, 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 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 in movie, music, and image files.

Here are a few of the best free video converters (such as MP4 and AVI), audio converters (MP3, WAV, etc.), image converters (e.g. PSD, JPG, and PNG), and document converters (PDF, DOCX, etc.).

Most document converters support common formats such as DOC, DOCX, PDF, PPT, PPTX, TIF, TXT, WKS, XLS, XLSX, and much more. Some free document converters can even convert image formats with text information to actual text-based files, allowing you to edit the information you couldn't before. This is called optical character recognition (OCR).

There's no need to buy a program when you can use any of these at absolutely no cost.


If you're looking to convert a PDF file to Microsoft Word's DOC or DOCX format, dedicated free PDF-to-Word converters may work a bit better.

Obviously, not all files contain video, audio, images, or documents. The free file converters here convert between many less common formats.

These disc image converters (ISO, IMG, etc.), font converters (TTF, OTF, DFONT, etc.), compressed file converters (ZIP, RAR, 7Z, CAB, etc.), and much more are all available free of charge.

If you're not sure what file type you need to convert, and none of the previously discussed converters were useful, one of these miscellaneous converters might be helpful.
