MP3 to WAV Converter

Convert MP3 files to WAV on your device. Choose your audio bitrate and convert privately with FFmpeg WebAssembly. Files never leave your browser. Start with a short clip: large files require substantial memory and processing time.

.mp3 · Up to 100 MB per file

    On first use, about 10 MB of conversion software downloads from this site. Your files stay local. Short clips work best; processing stops after ten minutes. Unsupported codecs, protected files, or insufficient memory can prevent conversion. Bitrate applies to lossy audio outputs; WAV and FLAC use lossless encoding. Extra tracks, subtitles and metadata are not preserved.

    3. Convert locally. On first use, the media engine downloads about 10 MB of software.

    Frequently Asked Questions

    Clear answers regarding conversion, privacy, and technical capabilities.

    Are my files uploaded?

    No. The browser downloads conversion software from this website, then processes your file in a local Web Worker. There is no conversion server.

    Will every file with these extensions work?

    Container support does not guarantee every codec variant. Damaged, encrypted, DRM-protected or unusually encoded media may fail. Keep your original files.

    What are the size and time limits?

    Inputs are limited to 100 MB and processing to ten minutes per job. Large or long media can exceed your device memory. Mobile devices should start with short clips. Video output is capped at the selected resolution, up to 1080p.

    Does changing the format improve quality?

    Re-encoding can lose quality. Converting a lossy source to a lossless format cannot restore discarded detail. Metadata, subtitles, extra tracks and attachments are not retained; the first video/audio track is used.
