Supported files
WEBM in. PCM WAV out.
WEBMWAV
The fixed server profile maps the first audio stream and writes signed 16-bit PCM WAV; it does not simply rewrap the original WEBM audio.
How it works
Extract a WEBM soundtrack as WAV.
Convert in sequence
Start the queue; each item runs separately through the fixed PCM WAV profile.
Download each WAV
Review the result audio where browser support allows, then save its separately named WAV file.
WAV output facts
Uncompressed-style PCM can be larger.
Video, metadata, and chapters are removed. WAV output is newly encoded PCM signed 16-bit, so it can be substantially larger than a compressed source.
Extract WEBM to WAVAudio stream required
A WEBM without audio cannot make a WAV. Only the first audio stream is selected when there are several.
Video is excluded
The result is audio-only; video, subtitles, attachments, and alternate tracks are not retained.
Fixed PCM encoding
FFmpeg creates signed 16-bit PCM WAV. This is not a stream copy, offers no audio controls, and may make a larger file.
Tags and chapters are removed
The profile removes source metadata and chapters. There are no trim, sample-rate, channel, bitrate, codec, or stream-selection options.
WEBM to WAV help
WAV conversion questions.
What WEBM files can become WAV?+−
Use a non-empty .webm upload no larger than 100 MB that host FFmpeg can read and that contains audio.
Does the WAV include video?+−
No. The profile maps the first audio stream and disables video, creating audio-only output.
What codec is in the WAV?+−
The route encodes PCM signed 16-bit little-endian audio.
Will WAV be smaller?+−
No size outcome is promised. PCM WAV can be much larger than compressed WEBM audio.
Are multiple audio tracks preserved?+−
No. The converter maps only the first audio stream; alternate tracks are not retained.
Does it retain metadata or chapters?+−
No. Source metadata and chapters are removed before the WAV is written.
Can I trim or change sample rate?+−
No. This route has no editing, sample-rate, channel, bitrate, or codec controls.
