Convert AVI to MP3

Old AVI clips from a digital camera or camcorder often hold a birthday song, a school play or a grandparent's voice. Save that sound as an MP3 you can play anywhere.

How to convert AVI to MP3

  1. Find the old AVI clips

    Copy the .avi files from the old camera card, CD or backup drive to your computer and drop them onto the page.

  2. Turn them into an MP3

    Choose MP3 as the output and click Convert to MP3. DivX, Xvid and older camera AVI files all work, since only the sound is kept.

  3. Play it back and keep it

    Listen to the MP3 right on the page, then download it and add it to a family playlist or a shared folder.

Keeping the sound of old clips

Many digital cameras from the 2000s saved AVI files, and today's phones and TVs often won't open them. The picture may be small and grainy, but the sound is often what matters most. An MP3 plays on almost any device made in the last twenty years.

Adapterry reads the first audio track of each AVI and writes a 192 kbps, 48 kHz stereo MP3. If you add a whole folder of short clips, they are joined in the order shown in the list, so a day of family clips becomes one MP3.

Questions and answers

Can I make one MP3 from a folder of short AVI clips?

Yes. Add them all, check the order (files are sorted by name, and you can drag them around) and click Merge & convert to MP3.

Why does my old camera AVI give an error about sound?

Some cameras recorded video without audio. If an AVI has no sound at all, there is nothing to turn into an MP3, and Adapterry tells you.

Will the MP3 sound better than the AVI?

No converter can add detail that was never recorded. The MP3 keeps the AVI's sound as it is, saved at 192 kbps stereo.

Can I hear the result before saving the MP3?

Yes. Browsers can't play AVI, but they can play MP3, so a player appears on the page once the audio is ready.

Are old home videos uploaded anywhere?

No. The AVI files are read and converted on your computer. Adapterry only counts anonymous things like the format and a rough size range.
