A whole folder to convert, or one file nothing will open?
Dropping several files at once is something this page now handles. A whole large folder, or rescuing an odd container your machine refuses to read, is still hand work. Our team takes those on.
Convert audio and video files to MP3, WAV, M4A directly in your browser (FLAC accepted as input). No installs, no uploads (total privacy). Note: This only changes the file's container; it cannot make the original audio sound better.
What is audio format conversion?
- Lossless (WAV, FLAC): Keeps 100% of the original sound, but files are huge.
- Lossy (MP3, M4A): Discards frequencies the human ear barely notices to shrink file size.
Does converting MP3 to WAV make it sound better?
How to maintain the best quality when converting?
- If your source is WAV/FLAC: Keep the original if you can; this page's lossless export option is WAV.
- If you need smaller files: Compress straight from the original source to MP3 or M4A once. Never compress an already compressed file.
Does round-trip converting degrade quality?
Quick format selection guide
| Use Case | Format | Why |
|---|---|---|
| Sharing, emails, older devices | MP3 | Universal compatibility, very small size. |
| Listening on modern devices | M4A | Better sound than MP3 at the same file size. |
| Professional audio/video editing | WAV | 100% original quality, zero compression latency. |
| Long-term storage | WAV | This page exports WAV/MP3/M4A only; FLAC is accepted as input but never as an export. |
