About formats

AAC

AAC (Advanced Audio Coding) is a lossy audio codec standardized by MPEG, designed as the successor to MP3. AAC delivers better sound quality than MP3 at the same bitrate and is the default audio codec for YouTube, iTunes, Apple Music, and most modern streaming services.

Frequently Asked Questions

Is converting AAC to WAV free?
Yes. This AAC → WAV 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 AAC to WAV?
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 AAC files uploaded to a server?
No. Files never leave your device. The entire AAC → WAV conversion runs locally in your browser, so your data stays private.
Can I convert multiple AAC files at once?
Yes — batch conversion is supported. Add as many AAC files as you like and convert them to WAV 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 AAC to WAV lose quality?
No. WAV is a lossless format (or used in a lossless mode here), so the original data from your AAC file is preserved bit-for-bit in the converted result.
Does WAV support transparency?
No — WAV has no alpha channel. Transparent areas of your AAC file will be filled with a solid background colour in the converted file.
How will the file size change after converting AAC to WAV?
Both formats use comparable compression, so the WAV output will be similar in size to your AAC file — typically within 10–20% of each other.
