How to Convert MP3 to WAV Online

This tool takes a MP3 file, processes it with FFmpeg on DownloadVideo.vn servers and returns a WAV file.

MP3 is lossy while WAV stores data exactly. The WAV file will be larger but not better: detail discarded by MP3 cannot be restored.

Property	MP3	WAV
Full name	MPEG-1 Audio Layer III	Waveform Audio File Format
Introduced	Fraunhofer / MPEG, 1993	Microsoft & IBM, 1991
Compression	lossy	uncompressed
Strengths	plays everywhere: phones, cars, speakers, browsers; about 1 MB per minute at 128 kbps	bit-perfect PCM audio for editing and mastering; accepted by every audio editor
Limitations	lossy: removed detail cannot be recovered; less efficient than AAC or Opus at the same bitrate	very large: about 10 MB per minute at CD quality (44.1 kHz, 16-bit, stereo)

On September 25, 2026 we ran the tool on our production server with a sample file: 10 seconds of 44.1 kHz stereo audio (MP3 192 kbps), 236 KB.

Result: 236 KB → 1.7 MB, processed in 1.4 s. Output: PCM 16 bit audio at 44.1 kHz stereo, 1411 kbps.

Real sizes depend on your content (how complex the picture and sound are, and the length); the figures only show the order of change.

The tool always re-encodes the picture and sound, even when the source codec would already fit the target format.
Up to 500 MB per file; a conversion that runs longer than 10 minutes is cancelled.
The file is sent to our server for conversion and deleted as soon as processing ends, including when it fails.

No. WAV only stores exactly what is left in the MP3; what was lost when the MP3 was compressed does not come back. The file just gets larger.

With our sample file: 236 KB → 1.7 MB. Your file may differ depending on its content.
