02

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

What is a WebM file?

WebM is an open, royalty-free audiovisual media file format sponsored by Google, derived from the Matroska (MKV) container. Designed specifically for the HTML5 video element, it restricts streams to specific codecs: video is compressed using VP8, VP9, or AV1, while audio utilizes Vorbis or Opus. The format structure is defined by a subset of the Matroska specifications, prioritizing efficiency for web streaming and low computational overhead for decoding in browser environments.

How to open a WebM file

As a native HTML5 format, WebM files open directly in modern web browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera without plugins. For offline playback, cross-platform media players like VLC media player, MPV, and FFmpeg-based tools provide full support. Windows Media Player may require the installation of WebM Media Foundation Components to render these files.

What is a WAV file?

The Waveform Audio File Format (WAV) is a raw audio bitstream standard developed by Microsoft and IBM, serving as a subset of the Resource Interchange File Format (RIFF) specification. It primarily stores uncompressed Linear Pulse Code Modulation (LPCM) audio data, making it the industry standard for archival and high-fidelity mastering on Windows systems. The format supports varying bit depths and sample rates, with the Red Book standard (44.1 kHz, 16-bit stereo) being the most prevalent implementation.

How to open a WAV file

WAV files enjoy near-universal native support across all major operating systems due to their status as a foundational audio standard. Windows Media Player, Apple QuickTime, and Linux-based media players (via ALSA/PulseAudio) open WAV files by default without requiring external codec packs or third-party software.
