About formats

WAV

WAV (Waveform Audio File Format) is a raw, typically uncompressed audio container developed by Microsoft and IBM based on the RIFF structure. WAV preserves full audio fidelity and is the format of choice for studio recording, archival, and professional audio editing, although file sizes are much larger than compressed formats.

Frequently Asked Questions

Is converting WAV to AAC free?
Yes. This WAV → AAC converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert WAV to AAC?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my WAV files uploaded to a server?
No. Files never leave your device. The entire WAV → AAC conversion runs locally in your browser, so your data stays private.
Can I convert multiple WAV files at once?
Yes — batch conversion is supported. Add as many WAV files as you like and convert them to AAC in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting WAV to AAC reduce the quality?
Because both formats use lossy compression, the AAC output will not bring back any quality that has already been lost in your WAV file. Avoid repeated re-encoding to keep the best quality.
Does AAC support transparency?
No — AAC has no alpha channel. Transparent areas of your WAV file will be filled with a solid background colour in the converted file.
Will the converted AAC file be smaller than the WAV?
Usually yes. Converting from a lossless or uncompressed format to a lossy one dramatically reduces file size. Typical savings range from 50% to 90%, depending on the quality setting you choose.
