Decode an MP3 file into an uncompressed WAV. The conversion cannot recover detail the MP3 already discarded, but a WAV copy is what most DAWs, samplers, and broadcast tools require for import.
MP3 is the most compatible audio format ever made. It plays on every device built in the last 25 years, from a $5 Bluetooth speaker to a Tesla, and 320 kbps MP3 is sonically indistinguishable from CD for most listeners. Pick MP3 when you want a file that will simply play, everywhere, without anyone asking what a codec is.
WAV is uncompressed PCM audio — the same lossless signal a CD or studio session uses. A three-minute WAV is roughly 30 MB versus 7 MB for MP3, but every sample is preserved. Use WAV when you plan to edit, master, sample, or archive the audio and need zero generation loss.
Server-side ffmpeg + yt-dlp on auto-scaling workers. Most files finish in seconds, not minutes.
Every uploaded or fetched file is virus-scanned before it ever reaches your download.
Files live on encrypted S3 storage for 2 hours, then are permanently purged. We never log file contents.
Free for up to 10 conversions per hour with no account. Pro unlocks larger files and priority queue.
Drop a MP3 file from your device, or paste a public URL pointing to the MP3 you want to convert.
The output is pre-set to WAV. You can adjust quality or bitrate in the advanced options if you need a smaller file.
Click Convert. Our cloud workers fetch the MP3, scan it for malware, and run the MP3 → WAV pipeline.
A one-time pre-signed link appears as soon as the WAV is ready. The file is automatically deleted from our storage 2 hours later.
