Anyone who works with videos will require a video downloader, a free video converter and compressor among other tools. Given the plethora of video formats, limits on sizes of videos you can upload and the compatibility issues across operating systems as well as specific devices, you need to find the best free video converter, downloader, compressor and perhaps also an extension so you can get your job done easily and more efficiently.

Part 1. Online Free Video Converters

Here are five online free video converter applications that you may consider.

1. Wondershare Online UniConverter

Wondershare Online UniConverter is available for both Windows and Mac. It is one of the best free online audio/video converters, editor, compressor, screencaster, and mixer. It supports more than 100 types of file formats, including MP3, MP4, OGG, VLC, MOV, AAC, WAV, and more. The software not only edits a file, but while editing/trimming, it also reduces the file size to save your PC memory. Also, the audio trimmer is considered to be the fastest audio trimmer.

2. Zamzar


Zamzar is a free video converter that you can use entirely online. However, the tool actually emails you the converted video. Free interfaces often don’t fare well on security measures and that may be a concern with Zamzar as well. The application scores really well in terms of the video formats it can work with and the devices its output formats are compatible with.

3. Convert.Files


Convert.Files can work with 3GP, AMV, ASF, AVI, FLV, MKV, MOV, M4V, MPEG, MPG, RM, VOB, WMV, M2T, M2TS, MTS and MOD. It can convert these video files to almost all popular video formats including 3GP, AVI, MOV, WMV, M4V, AMV, FLV, MP4, MPEG, VOB, MKV and ASF. The application is not among the most efficient and there are no enhancement tools or edit suite but it gets the basic job done.

4. Online-Convert

Online-Convert lets you convert videos to 3G2, 3GP, AVI, FLV, MKV, MOV, MP4, MPEG-1, MPEG-2, OGG, WMV and WEBM. You can also convert videos specifically for Android phones, iOS devices iPhone and iPod, BlackBerry devices and Nintendo consoles. There are many video formats not covered by Online-Convert. The online interface doesn’t provide any edit suite or tools that can assist you in conversion quality or compression.

5. Free Online Video Converter
