Queue AAC audio
Choose one or more non-empty .aac files up to 100 MB each. A source audio control appears when the browser can decode that AAC file.
Free online AAC to WAV converter
Create PCM WAV audio from AAC files.

AAC in. WAV out.
AACWAV
Add AAC audio files up to 100 MB each. Fileverses creates a new WAV result with this route’s documented conversion profile; review the completed download before using it elsewhere.
How it works
One queue. A new WAV file.
Create PCM WAV audio
Start the queue to have FFmpeg map the first audio stream from each AAC file and encode it as a new PCM signed 16-bit little-endian WAV.
Listen and download
Inspect every completed WAV in the queue, then download that separately named audio result.
Limits and quality
A new WAV file, with source-specific trade-offs.
Each result is a newly encoded PCM signed 16-bit little-endian WAV, not copied AAC audio. WAV can be substantially larger than compressed AAC, has no promised output size, and cannot recover earlier audio detail.
Convert AAC nowAAC sources with audio
This route accepts non-empty .aac files up to 100 MB each. The selected file must be readable by the host FFmpeg installation and have an audio stream.
New uncompressed PCM WAV
Each result is a newly encoded PCM signed 16-bit little-endian WAV, not copied AAC audio. WAV can be substantially larger than compressed AAC, has no promised output size, and cannot recover earlier audio detail.
First audio stream only
The profile maps only the first audio stream, removes source metadata and chapters, and excludes video. It does not preserve alternate audio tracks, subtitles, attachments, original codecs, or metadata, and has no trimming, sample-rate, channel, or bitrate controls.
AAC to WAV FAQ
Questions, answered.
What AAC files can I convert to WAV?+−
This converter accepts non-empty .aac files up to 100 MB each. FFmpeg must be able to read the AAC file and find an audio stream for conversion to succeed.
What does the downloaded WAV contain?+−
A successful result is a newly encoded WAV with PCM signed 16-bit little-endian audio. It contains only the first audio stream from the AAC source.
Can I convert several AAC files at once?+−
Yes. Add multiple supported AAC files to the queue. The browser submits one real server-side conversion at a time, and every successful row receives its own WAV player and download button.
Will the WAV be smaller or recover original quality?+−
No. PCM WAV is uncompressed and can be much larger than AAC audio. The new encode cannot restore detail lost in an earlier source, and the final size depends on the source and encoder output.
Does this keep alternate audio tracks or metadata?+−
No. The profile maps only the first audio stream, removes source metadata and chapters, and excludes video. It does not promise alternate-track, subtitle, attachment, original-codec, or metadata preservation.
Can I choose WAV settings or trim the audio?+−
No. This route has no trimming, stream-selection, sample-rate, channel, bitrate, or quality controls. It uses its fixed PCM signed 16-bit little-endian WAV profile.
Are files kept after conversion?+−
Each source and output exists in a temporary server directory only while its conversion runs. The directory is removed whether the job succeeds or fails.
