Why Convert WebM to WEBA?
WebM is Google's video format containing both video and audio tracks. WEBA (WebM Audio) is the audio-only variant — same container, no video. Converting WebM to WEBA strips the video track, which is useful for extracting audio from web videos for podcast or music use, reducing file size by removing the video track entirely, creating audio-only files for HTML5 <audio> elements, and serving web audio in a royalty-free format supported by Chrome, Firefox, and Edge.

What is the difference between WEBA and WebM?
WEBA (.weba) is audio-only, while WebM (.webm) contains both video and audio. Both use the same WebM container. WEBA files are much smaller since there is no video track.
Can I trim the audio during conversion?
Yes. Under Trim, switch to "Trim" and enter a Start Time and Duration. This extracts audio from a specific portion of the WebM video.
Does WEBA work in Safari?
Safari has limited WebM/WEBA support. For full cross-browser compatibility including Safari, convert to WebM to MP3 or WebM to M4A instead.
What bitrate should I use?
For voice/podcast content, 64-96 kbps is sufficient. For music, use 128-192 kbps. The original WebM audio quality limits the maximum useful bitrate.
Why is the default codec AAC instead of Opus?
The default audio codec is AAC (first option). You can change to Opus under Audio Codec for the native WebM audio codec, which provides better quality at lower bitrates.
