This versatile audio converter lets you convert WAV to MP3, OGG to MP3, MP3 to M4A, and even video to audio such as MP4 to MP3.

Convert to MP3, OGG, M4A, AAC, FLAC, WAV, WMA, AIFF, OPUS, M4R, or MMF. MP3 is used unless you pick another format.
Upload an MP4, MOV, or AVI file and keep only the sound. It is the short way from a video to an MP3.
Add a whole batch and convert it in one go. Nothing is installed, so the page works on Windows, macOS, Linux, Android, and iOS.
Upload your audio or video file.
Choose the audio format you want to convert your file to.
Use the optional settings to further customize your file. (optional)
Click "Start" to begin the audio conversion.
The audio converter writes 11 formats: AAC, AIFF, FLAC, M4A, M4R, MMF, MP3, OGG, OPUS, WAV, and WMA. MP3 is the safe default, because it plays on almost every phone, car stereo, and media player.
Choose FLAC or WAV when the file has to keep every detail, for example a recording you still want to edit. Choose AAC, M4A, or OPUS when you want a small file that still sounds good on headphones. M4R is the iPhone ringtone format, and MMF is used by older Yamaha handsets.
There are different types of audio files based on their compression: lossless and lossy. Some audio formats can use both types of compression.
The advantage of lossless audio files is their high sound quality. For example, audiophiles often prefer the quality of a FLAC file over any lossy audio file. Lossy files, however, are much smaller in size. That is why lossy formats like MP3 are more common and better supported.
Every conversion starts on automatic settings, so you can upload a file, pick a format, and start straight away.
When you need more control, the optional settings hold the bitrate, the sample frequency, and the channels. A bitrate of 192 kbit/s or more keeps music close to the original, while 96 kbit/s is enough for speech. Mono roughly halves the size of a voice recording, and volume normalization evens out tracks that were recorded at different levels.
The audio converter creates AAC, AIFF, FLAC, M4A, M4R, MMF, MP3, OGG, OPUS, WAV, and WMA files. Common audio and video files are accepted as input, so WAV to MP3, OGG to MP3, and MP4 to MP3 all work here.
Yes. Everyday music, podcast, and voice files convert for free, and no account is needed. A subscription raises the size limit and skips the queue if you convert long recordings regularly.
Yes. Upload an MP4, MOV, AVI, or similar video and the sound track is written to the audio format you picked. The picture is dropped, which is why the result is much smaller than the video.
Yes. Add as many files as you need before you start. They are converted in one batch and each one comes back as a separate audio file.
Converting into a lossy format such as MP3, AAC, or OGG re-encodes the sound, so a little quality is lost. At 192 kbit/s or higher the difference is inaudible for most music. Convert to FLAC or WAV when you want to keep the audio exactly as it is.
Choose MP3 for sharing and for players and car stereos, because it is small and supported everywhere. Choose FLAC for archiving or editing, because it keeps the full quality at roughly half the size of a WAV file.
