Turn your AAC audio files into the universally supported MP3 format quickly and for free. By default the conversion happens directly in your browser, so your files never leave your device.
In “Local” mode your file never leaves your device. No uploads, no server – ideal for sensitive recordings.
Pick “Local” for full privacy or “Server” for very large files and every format.
No sign-up, no queue, no watermark. Choose a file, convert, download.
Both formats are lossy, so this is a transcode that can shed a little extra quality. At a high enough bitrate the difference is inaudible to most listeners.
MP3 plays on virtually every device, car stereo and legacy player. Converting guarantees maximum compatibility when something refuses to read AAC.
No. By default the whole conversion runs locally in your browser. An optional server mode is only there for very large files.
192 to 320 kbps works well for music. Choosing a bitrate higher than the source AAC won't add quality, it only makes the file bigger.
