How to convert FILE to WAV
WAV is an uncompressed audio format developed by Microsoft and IBM in 1991. It stores audio as raw PCM samples with no lossy encoding, which is why audio engineers, video editors, and recording software treat it as the standard for working with audio at full quality. Converting any audio file to WAV is necessary when your target software requires uncompressed input, when you are preparing audio for broadcast or professional post-production, or when you want to archive audio without encoding artifacts.
This converter decodes whatever audio format you upload and writes the result as WAV entirely in your browser using WebAssembly. Your audio never leaves your device. The output is uncompressed PCM at the original sample rate and bit depth, preserving every sample from the source file.
Upload your audio file
Drop any audio file onto the converter: MP3, AAC, FLAC, OGG, M4A, AIFF, AMR, and other common formats are accepted. The decoder identifies the format automatically.
Choose sample rate and bit depth
Leave these at the source file's original values unless you have a specific target requirement. CD-quality audio is 44,100 Hz at 16 bits. Professional audio is often 48,000 or 96,000 Hz at 24 bits.
Convert in browser
The WebAssembly engine decodes the compressed audio and writes uncompressed WAV samples. Files converted from compressed formats like MP3 will be much larger than the source, since WAV does not compress.
Download and import
Save the WAV file. A four-minute MP3 at 128 kbps is about 4 MB; the same audio as WAV at 44,100 Hz, 16-bit stereo is about 40 MB. Plan your storage accordingly.
Frequently asked questions
Does converting MP3 to WAV restore the audio quality lost during MP3 encoding?
No. The information discarded by the MP3 encoder is gone permanently. Converting to WAV makes the file uncompressed and larger, but it does not recover audio data that was thrown away when the MP3 was created.
Why does video editing software often require WAV?
Video editing software syncs audio and video frame by frame. Compressed audio formats like MP3 use variable-length encoding, which makes precise frame-level seeking difficult. Uncompressed WAV samples map to exact time positions, making synchronization reliable.
Is the audio uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly. Nothing is sent to any server.
What is the difference between WAV and AIFF?
Both WAV and AIFF store uncompressed PCM audio. WAV was developed for Windows; AIFF was developed by Apple. Technically they are nearly identical in quality. WAV is more universally supported on Windows and Linux; AIFF on older macOS workflows.
Can I convert lossless FLAC to WAV without any quality change?
Yes. Both FLAC and WAV are lossless formats. FLAC uses lossless compression; WAV is uncompressed. The PCM samples are bit-identical after conversion. The only difference is file size: WAV will be larger.
