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.). 01 of 05 Free Video Converters DryIcons Video converter software converts one kind of video file into another. Most video converters support popular formats such as 3GP, AVI, DIVX, F4V, FLV, V4V, MKV, MOV, MP4, MPG, SWF, WMV, and much more. Many video converters also convert DVD and BD movies into various other video formats such as MP4, FLV, AVI, etc. Some of these output formats are ideal for use on mobile devices. Dozens of fantastic, completely free video converters are available. 02 of 05 Free Audio Converters DryIcons Audio converter software converts one kind of audio file into another. Most programs support common music formats such as FLAC, OGG, M4A, MP3, WAV, WMA, and several more. Some also can extract audio information from video files. Among these high-quality, completely free audio converters, you'll find many that are online, which means you can use the software from right inside your web browser. 03 of 05 Free Image Converters DryIcons Image converter software converts one kind of photo or graphics file into another. The best image converters support hundreds of common and rare image formats, but almost all of them can convert BMP, EMF, GIF, ICO, JPG, PCX, PDF, PNG, PSD, RAW, TIF, WMF, and several others. Many image converters also feature batch operation, allowing you to convert several files into a particular format all at once. Some of the best available are completely free, and some even work entirely online so you don't have to download anything. 04 of 05 Free Document Converters DryIcons Document converter software converts one kind of document file—such as word processing, spreadsheet, database, presentation, etc.—into another of a similar type. 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. Tip 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. 05 of 05 Other Free Converters for Miscellaneous File Formats DryIcons Obviously, not all files are videos, audios, 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.
