Convert Sony Wave64 audio files (W64) online for free

The converter also works in reverse, so you can convert other "64-bit Audio Container" formats to W64 without using software like Sound Forge or a similar tool.
A .w64 file is a Sony Wave64 audio file, an uncompressed format engineered to solve a specific limitation: the 4GB file size cap of standard WAV files. While standard WAVs (based on the RIFF specification) use 32-bit headers that cannot address data beyond 4 gigabytes, Wave64 uses 64-bit headers, theoretically allowing for exabytes of audio data. This makes .w64 essential for long-duration recordings (like multi-hour podcasts or concert archival) or high-resolution multi-channel mastering in software like Sound Forge and Vegas Pro.
However, this format is purely for production, not distribution. You likely cannot open a .w64 file in Windows Media Player, QuickTime, or web browsers, and the file sizes are often unmanageably large for sharing via email or cloud storage. To make the audio accessible, you should convert it. For archiving without losing quality, convert to FLAC (which supports large files and compression). For general listening or web use, convert to MP3 or AAC. If the file is under 4GB and you need broad compatibility, converting back to standard WAV is the safest option.
