About formats

ALAC

ALAC (Apple Lossless Audio Codec) is a lossless audio codec developed by Apple and open-sourced in 2011. ALAC compresses audio without quality loss and is used in Apple Music's high-fidelity tier. ALAC files are typically stored in M4A containers and are supported by all Apple devices and most modern players.

MP3

MP3 (MPEG-1 Audio Layer III) is the most popular lossy audio compression format, designed by the Moving Picture Experts Group. It drastically reduces file size while preserving near-CD quality by discarding sounds that are inaudible to most listeners. MP3 is supported by virtually every audio player, device, and platform ever made.

Frequently Asked Questions

Is converting ALAC to MP3 free?
Yes. This ALAC → MP3 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 ALAC to MP3?
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 ALAC files uploaded to a server?
No. Files never leave your device. The entire ALAC → MP3 conversion runs locally in your browser, so your data stays private.
Can I convert multiple ALAC files at once?
Yes — batch conversion is supported. Add as many ALAC files as you like and convert them to MP3 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 I lose quality converting ALAC to MP3?
Yes — MP3 uses lossy compression, so the converted file will discard some information from your lossless ALAC. Choose a high quality setting to minimise the visible loss.
Does MP3 support transparency?
No — MP3 has no alpha channel. Transparent areas of your ALAC file will be filled with a solid background colour in the converted file.
Will the converted MP3 file be smaller than the ALAC?
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.
