Frequently Asked Questions
WAV is uncompressed and lossless, but since the original WebM audio track (Opus or Vorbis) is already lossy-compressed, you won't recover quality that was lost during WebM encoding. However, you won't lose any additional quality — WAV preserves exactly what's in the WebM.
No. WAV is a pure audio format. ChangeThisFile extracts only the audio track from your WebM video — the video stream is discarded.
WAV is uncompressed, making it ideal for further audio editing, professional workflows, or archiving. MP3 re-encodes and compresses the audio again, adding generation loss. Choose WAV when you plan to edit or process the audio.
Most WebM files convert in under 30 seconds. Larger files or longer videos may take up to a minute depending on server load.
Yes. Your file is uploaded over an encrypted HTTPS connection and is automatically deleted from our servers immediately after conversion. We do not store, share, or analyze your files.
ChangeThisFile uses FFmpeg, which supports all common WebM audio codecs including Opus and Vorbis. Both will be extracted and converted to WAV correctly.
If the WebM file contains no audio stream, the conversion will fail or produce an empty file. Screen recordings and some video files may have no audio — check your source file first.
Currently ChangeThisFile processes one file at a time. For batch conversions, you can convert files one after another — each conversion is fast and free.
