Audio/Video Converter
Convert between MOV/MP4/MP3/WAV and strip audio from video.
How it works
Convert between common audio and video formats — MOV to MP4, WAV to MP3, or extract/strip audio from a video — right from this page, powered by FFmpeg.
- Drop an audio or video file onto the upload area, or click to select one.
- Choose a conversion preset (e.g. .mov → .mp4, strip audio from video).
- Click Convert — the first run loads the ~30MB conversion engine, so it takes longer than subsequent conversions.
- Download the converted file once processing finishes.
Common use cases
- Converting a .mov screen recording to .mp4 for compatibility with a video editor or upload form.
- Extracting the audio track from a video file as an MP3.
- Stripping audio entirely from a video to create a silent background loop.
- Converting a WAV recording to MP3 to shrink file size before sharing.
FAQ
- Why does the first conversion take so long?
- The tool loads an FFmpeg WebAssembly engine (~30MB) the first time you convert something on this page. Once loaded, subsequent conversions in the same session are much faster.
- Is there a file size limit?
- Very large video files can be slow or memory-intensive to process — for large batch conversions, a dedicated desktop tool will generally be faster.
- What formats are supported?
- The listed presets cover the most common conversions (MOV/any video → MP4, WAV/any audio → MP3, and audio extraction/stripping). Support depends on the underlying FFmpeg build's codecs.
