What is a WEBA file?
WEBA stands for WebM audio. It was created by Google and first released in 2010. A WEBA file is a WebM container with sound and no picture, almost always Opus. Chrome saves microphone recordings this way, and YouTube downloaders produce it because YouTube streams its audio as WebM Opus.
| Type | audio |
|---|---|
| Compression | Lossy |
| Usually contains | Opus or Vorbis audio in a WebM container |
| In a browser | plays in Chrome, Firefox and Edge; Safari plays it only in recent versions |
| Common uses | audio saved from YouTube and voice recordings made in a browser |
| MIME type | audio/webm |
Which format should you convert WEBA to?
- WEBA to MP3 to play on any device, car stereo or website.
- WEBA to WAV to edit in an audio editor or burn to CD.
WEBA is already lossy, so converting it to a lossless format makes the file bigger without improving it; pick a lossless target only if a program requires one.
How to open a WEBA file
Whether a WEBA file opens with a double click depends on the device. Here is what works on each, without buying software:
| Windows | Films and TV and Media Player open the common formats; VLC opens almost any audio file, WEBA included. |
|---|---|
| Mac | QuickTime Player opens formats Apple supports; VLC or IINA open the rest. |
| iPhone and iPad | The Files app plays formats Apple supports. For others, a player such as VLC for iOS, or converting the file here, is the easiest route. |
| Android | Most gallery and music apps play the common formats; VLC for Android plays almost everything. |
| Web browser | WEBA plays in Chrome, Firefox and Edge; Safari plays it only in recent versions. |

WEBA compared with other audio formats
How WEBA stacks up against the formats people most often convert it to or from:
| Format | Compression | Usually contains | Released | Best for |
|---|---|---|---|---|
| WEBA | Lossy | Opus or Vorbis audio in a WebM container | 2010 | audio saved from YouTube and voice recordings made in a browser |
| MP3 | Lossy | MP3 audio, typically 128 to 320 kbps | 1993 | music libraries, podcasts and anything that has to play everywhere |
| WAV | Lossless | uncompressed PCM, usually 16-bit at 44.1 or 48 kHz | 1991 | recording, editing, sound effects and CD audio |
| M4A | Either | AAC, or ALAC for lossless files | 2001 | iTunes purchases, iPhone voice memos and Apple Music downloads |
| FLAC | Lossless | FLAC lossless audio, up to 32-bit and 655 kHz | 2001 | CD rips, hi-res music stores and audio archives |

- Adjust the settings if you need to; the defaults suit most people.
- Press Convert and save each file with its Download button. Nothing is uploaded at any point.
Tips for converting WEBA files without losing quality
WEBA is lossy, so some detail was already discarded when the file was made. Converting it cannot bring that back. Converting to a lossless format preserves what is left exactly but makes the file larger; converting to another lossy format adds a small extra loss, which is invisible at sensible settings.
- Keep a lossless master. If you have WAV, FLAC, AIFF or ALAC, keep it, and make lossy copies such as MP3 or AAC from it when you need them.
- Avoid converting one lossy format into another more than once. Each MP3, AAC or OGG encode throws away a little more, and the losses add up.
- Match the bitrate to the content: 192 kbps and up for music, 96 to 128 kbps for podcasts, 64 kbps for voice notes.
- Stick to 44.1 kHz for music and 48 kHz for audio that goes with video; resampling between them is harmless but pointless.
Convert WEBA files from the command line
Everything this page does can also be done in a terminal. The most common WEBA conversion, to MP3, looks like this with ffmpeg:
ffmpeg -i input.weba -vn -c:a libmp3lame -b:a 192k output.mp3Change the output extension to pick another format. The converter above runs the same ffmpeg engine inside your browser, so you get the result without installing anything.
