Quality reduction ahead
WAV is uncompressed, meaning every bit of data is preserved. AAC uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your WAV file may contain RIFF chunks, BWF metadata metadata. AAC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
AAC lossy compression can produce pre-echo at low bitrates. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

About WAV to AAC Conversion
Short answer: yes, you can convert WAV to AAC online for free, and quality is well preserved with the right settings. Just upload your .wav file to CocoConvert, pick AAC as the output, and click Convert. The whole process takes seconds.
Now for the details. WAV is uncompressed PCM audio — studio quality with no data loss, but large file sizes. AAC (Advanced Audio Coding) offers better quality than MP3 at the same bitrate — the default codec for Apple devices. Converting between these two formats lets you reduce file size without visible quality loss.
Full Name: WAV uses Waveform Audio, while AAC uses Advanced Audio Coding. Compression: WAV uses None (uncompressed), while AAC uses Lossy. Typical File Size: WAV uses 10 MB per minute at 44.1 kHz/16-bit stereo, while AAC uses 1 MB per minute at 128 kbps.
Your WAV file is decoded and re-encoded as AAC. AAC lossy compression can produce pre-echo at low bitrates. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert WAV to AAC
Your WAV audio is decoded into raw PCM samples, then re-encoded as AAC. Some audio data is permanently discarded during compression.
Your WAV file is decoded — compressed audio becomes raw PCM waveform data
The raw audio is re-encoded using Advanced Audio Coding's lossy codec
Metadata (tags, artwork, track info) is transferred where AAC supports it
The AAC file is saved and ready for download

Frequently Asked Questions
Is WAV to AAC conversion free?
Yes. CocoConvert offers free WAV to AAC conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is WAV to AAC conversion?
Most files convert in 2–10 seconds depending on size. Large audio files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded WAV file and the converted AAC file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting WAV to AAC lose quality?
AAC lossy compression can produce pre-echo at low bitrates. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
Can I convert AAC back to WAV?
Yes, CocoConvert supports AAC to WAV conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
