What is a Codec?
A codec (coder-decoder) is software that compresses and decompresses digital media files. Without the right codec, your media player won't be able to play certain video or audio files. Common video codecs include H.264, H.265 (HEVC), VP9, and AV1. Common audio codecs include AAC, MP3, FLAC, and Opus.
If you're seeing error messages like "codec not found" or "unsupported format," this tool will help you identify exactly what you need to download.
