About formats

MP2

MP2 (MPEG-1 Audio Layer II) is a lossy audio codec that predates MP3. It is still widely used in digital radio broadcasting (DAB) and for the audio track of Video CDs, thanks to its simplicity and resilience to transmission errors.

Frequently Asked Questions

Is converting MP2 to AAC free?
Yes. This MP2 → 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 MP2 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 MP2 files uploaded to a server?
No. Files never leave your device. The entire MP2 → AAC conversion runs locally in your browser, so your data stays private.
Can I convert multiple MP2 files at once?
Yes — batch conversion is supported. Add as many MP2 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 MP2 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 MP2 file. Avoid repeated re-encoding to keep the best quality.
Does AAC support transparency?
No — AAC has no alpha channel. Transparent areas of your MP2 file will be filled with a solid background colour in the converted file.
How will the file size change after converting MP2 to AAC?
Both formats use comparable compression, so the AAC output will be similar in size to your MP2 file — typically within 10–20% of each other.
