What is a AAC file?
AAC (Advanced Audio Coding) is a lossy audio format designed as the successor to MP3. It delivers better sound quality at similar or lower bitrates and is the default format for Apple devices, YouTube, and most streaming platforms. AAC files typically use the .aac or .m4a extension.
What is a WEBM file?
WebM is a royalty‑free container designed by Google for the open web. It packages the Matroska profile with VP8/VP9/AV1 video and Vorbis/Opus audio, optimised for low overhead and HTML5 streaming. Announced at Google I/O 2010, WebM combined Matroska’s flexibility with On2’s newly open‑sourced VP8 codec. YouTube began offering WebM downloads the same year. Support grew as browsers added VP9 hardware decoding and will expand again with AV1.
