WebM is an open multimedia file format developed by Google's IT giant. It was first introduced by the developer on May 19, 2010 at the Google I / O conference. Typically, WebM files store video with compression using VP8 technology, as well as audio with compression using Ogg Vorbis compression. The initial developer of VP8 technology is ON2, which Google later acquired. WebM format provides efficient compression and high quality video. The format is supported by Google Chrome, Mozilla Firefox, and Opera. When installing the necessary codecs in Windows, this format is also supported in Internet Explorer.
ALAC is the format of a small specialized program called an audio codec. Its main task is to compress a file with digital music without losing its quality. The name of the format created by Apple's IT giant is Apple's abbreviation Lossless Audio Codec. This format may also be called ALE (from Apple Lossless Encoder). Files in this format can play devices even with limited computing resources - such as an iPod. When compressing a file in this format, it is approximately 40-60% of the original file. Now almost every multimedia player based on the libavcodec library is able to play ALAC format files.
