Frequently Asked Questions
Why convert AAC to WAV?
AAC (Advanced Audio Coding) uses lossy compressed encoding and is best for modern streaming services, YouTube, and devices where AAC is the native codec. WAV (Waveform Audio File Format) uses uncompressed lossless encoding and excels at professional audio editing, mastering, and archival in DAWs and production software. 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.
When using AAC to WAV, will the audio quality improve?
Converting from lossy AAC to lossless WAV does not restore lost quality. The WAV file will be larger but fidelity is limited by the original AAC compression. Useful for editing, not quality enhancement.
How large will the WAV file be?
WAV is uncompressed, so expect 5-10x the AAC file size. A 5MB AAC may become 30-50MB as WAV. This is normal for lossless audio.
What sample rates are supported?
The converter preserves the original sample rate and bit depth. AAC at 44.1kHz will output WAV at 44.1kHz with 16-bit or 32-bit depth.
Is AAC to WAV conversion done locally?
Yes. All conversion runs in your browser using FFmpeg WASM. No audio files are uploaded to any server.
