Conversion surface
Run the file task now.
The converter stays fast and simple. Workspace features only step in when retention, OCR, or repeat work actually adds value.
How it works
A short path from input to finished export.
The flow stays simple so you can get in, finish the job, and move on without extra setup.
Upload AVI Videos
Drag and drop your AVI videos or click to browse. You can queue several at once.
Convert in Your Browser
The first run fetches the conversion engine (a one-time ~31MB download); after that, AVI to WAV conversion happens entirely on your device — nothing is uploaded.
Download WAV
Save the converted file right away. Multiple files are bundled into a ZIP for one-click download.
Why FileMorf
A cleaner route for this conversion.
The tool keeps the core job lightweight while still giving you room to grow into retained, higher-value workflows later.
100% Private
All processing happens in your browser. Your files never leave your device.
Uncompressed PCM Audio
Output is standard 16-bit PCM WAV — the interchange format audio editors, DAWs, and production tools accept without codecs.
One-Time Engine Download
The first conversion fetches a ~31MB audio engine; your browser caches it, and everything runs locally from then on.
Details
Answers before you start.
The important questions, plus the nearby routes users usually need next.
Audio salvaged from old AVI footage usually needs work — hiss removal, level fixes, trimming — and that work happens in editors that want WAV input. Converting decodes whatever the AVI's audio track holds (often MP3 or AC-3 from the camcorder era) into plain PCM. From there, Audacity's noise reduction or any DAW's tools can take over, with no codec obstacles in the way.
No — it just stops further loss. The audio track inside a AVI is already compressed (typically AAC), and WAV stores that decoded track without re-encoding it. You get a file editors and DAWs accept directly, at exactly the quality that was in the video.
No — this tool extracts the audio track only. Converting the video itself into another video format (like MOV to MP4) is a much heavier job that FileMorf handles server-side through the main converter for signed-in users.
Up to 512MB in the browser. The engine holds the whole file in memory while it works, so there's a hard cap to keep things stable — larger files are better suited to server-side processing, which is available to signed-in users.
No. The entire AVI to WAV conversion runs locally in your browser. The only thing fetched is the conversion engine itself — a one-time ~31MB download that your browser caches. Your files never leave your device, and there is nothing for anyone else to store.
The first run downloads the audio engine — FFmpeg compiled to WebAssembly, about 31MB. Your browser caches it, so later conversions start immediately, whether you're converting one file or a whole batch.
