I tried it and immediately fell in love! It was so easy to use! After a couple conversions I bought the guys a cup of coffee. A couple more and decided this was too good to abuse! I joined! My life is so much easier!Tillie

I use Zamar whenever I need to convert audio and video files from multiple submitters to 1 uniform file format for Audio and Video Editing. I can do multiple large files in a short amount of time.Christopher Bee
Great thanks to you all for helping me to get the OLD files converted correctly. 20 years, quite a long time, reviewing the files brings much memory to me. That's the best gift I received last year. Thank you all again.Jiunn-Ru Lai

WEBM Video Format WEBM Converter
The WebM file format is a video format that was developed by On2 Technologies (who were acquired by Google in 2009). The format is a high quality and open format but, crucially, is small in size. WebM files have grown in popularity since HTML5 became standard for sites like YouTube and for popular devices like the iPhone.
The WebM format is based on the Matroska MKV format, which is a multimedia container format. WebM, like MKV, is made up of audio, video and subtitles in just a single file, with each element having its own type of encoding.
WebM videos can be quite difficult to open because most popular video players aren't able to play this format without first converting the file or installing specific software to play the file; a notable exception is the VLC media player, which is able to play most WebM files.
MP4 Video Format MP4 Converter
MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.
MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.
