M4A (MPEG-4 Audio) uses lossy or lossless (AAC/ALAC) encoding and is best for Apple ecosystem — iTunes, iPhones, iPads, and macOS music libraries. OGG (Ogg Vorbis) uses lossy compressed encoding and excels at open-source software, Linux systems, game development, and streaming on open platforms. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
