Why convert WAV to AAC?
AAC uses lossy compression, so expect a noticeably smaller file than the uncompressed WAV original, at some cost to quality. The main reason to convert WAV to AAC is compatibility: AAC plays on virtually any device or app without an extra codec, while WAV doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, AAC is usually the safer target.
Format comparison
| WAV | AAC | |

| MIME type | audio/wav | audio/aac |
| Compression | no compression scheme of its own | lossy compression |
| Category | audio | audio |
Common reasons to convert WAV to AAC
- Fitting more tracks on a device or app with limited storage
- Meeting a file-size limit for email or upload
- Cutting file size for storage or bandwidth, where some quality loss is an acceptable trade-off
What actually happens to your file
Going from uncompressed WAV to AAC at 192 kbps is usually a 5-10x size reduction. Since WAV is your true, uncompressed source, this is the best point in your workflow to introduce compression — AAC generally holds up better than MP3 at the same bitrate, so it's a solid default if this is the first time you're compressing this audio.
Your file, handled carefully
Uploads use TLS in transit and AES-256 SSE-S3 at rest in production (when the production S3 credential gate is enabled), are processed in an isolated job, and deleted on the schedule you choose — as fast as immediately. We don't index, search, or share files between accounts. Read the full security model →
Frequently asked questions
Is converting WAV to AAC free?
Yes — the Free plan includes 50 conversions every month, including WAV to AAC. Paid plans raise that limit.
Will I lose quality converting WAV to AAC?
AAC is efficient lossy codec used by streaming and apple devices. We use the highest-quality encoder settings by default so visual or data loss is minimized.
Do you keep a copy of my file?
Files are deleted automatically based on your plan's retention options. Free accounts can keep results for 1h or 24h; Pro and above add options such as delete-immediately and 7 days.
What is WAV?
Uncompressed PCM audio, the studio standard.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click. Monthly quotas count attempts (including failures) because processing starts as soon as the job is created.
