How do I convert AVI to MP3 using LetsConvert?

First, upload your AVI file to the converter. Then select MP3 as the output format (you can adjust bitrate and sample rate if needed). Click 'Convert' to extract the audio track from the AVI container and encode it as MP3. After processing, download your new MP3 file and enjoy it on any audio device.

Why convert AVI to MP3? What's the advantage?

AVI is a video container that includes both video and audio, making files large and often incompatible with audio-only players. Converting to MP3 extracts just the audio, reducing file size by up to 90% and ensuring playback on virtually any device or software—including smartphones, car stereos, and DAWs. It's also ideal for creating music clips or podcasts from video sources.

What happens to the audio bitrate and sample rate during AVI to MP3 conversion?

The audio is first decoded from the AVI file without quality loss, then re-encoded to MP3. You can select a bitrate from 64 to 320 kbps and a sample rate from 16 to 48 kHz. Choosing 320 kbps closely matches CD quality, while lower bitrates save space. The video data is discarded, so only the audio remains.
