Frequently Asked Questions
Why convert WAV to M4A?
WAV (Waveform Audio File Format) uses uncompressed lossless encoding and is best for professional audio editing, mastering, and archival in DAWs and production software. M4A (MPEG-4 Audio) uses lossy or lossless (AAC/ALAC) encoding and excels at Apple ecosystem — iTunes, iPhones, iPads, and macOS music libraries. 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.
