Question 1

How do I convert a WebM file to AAC?

Accepted Answer

Drag your WebM file onto the box above, or click Select file to choose it. Click Convert and wait for the progress bar to finish. Click Download to save the AAC file.

Question 2

Is AAC the right format for my WebM video?

Accepted Answer

Choose AAC only if an app or device asks for .aac files. An .aac file holds the same kind of sound as an M4A file without the container around it. Fewer apps open .aac files. For most uses, WebM to M4A is the better choice.

Question 3

Does converting to AAC lose quality?

Accepted Answer

A little. WebM videos usually store their sound as Opus or Vorbis, which AAC files can't hold. MakeAudio converts the sound to AAC at 192 kbps, which is high quality for music and speech.

Question 4

How big will the AAC file be?

Accepted Answer

The sound is saved as AAC at 192 kbps, which takes about 1.4 MB per minute. A 30-minute screen recording becomes an AAC file of about 43 MB. A 1-hour meeting recording becomes an AAC file of about 86 MB.

Question 5

Why isn't my video accepted?

Accepted Answer

This page accepts WebM files, whose names end in .webm. Most other videos are MP4, MOV or MKV files. Check the end of the file name and use the matching converter: MP4 to AAC, MOV to AAC or MKV to AAC.
