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.

What is a M4A file?

.m4a is the generic extension for audio‑only MP4 files. Inside, you will typically find AAC or ALAC streams plus metadata for chapters, cover art, and lyrics. The format provides gapless playback, efficient compression, and wide ecosystem support. Apple coined .m4a in 2001 to distinguish music downloads from copy‑protected .m4p tracks sold on the iTunes Store. Because MP4’s audio profiles required no licence fees, many podcasters and game developers adopted .m4a for better quality than MP3 at the same bit‑rate. Today .m4a is recognised by Android, Windows, and most car infotainment systems.
