Convert audio files to MP3 format

Convert any audio (M4A, WMA, WAV...) or video (MP4, AVI...) to MP3 without installing any software! Convertirvideo does this conversion for you with highest quality. As default setting your MP3 file will be ~250 kbps VBR (variable bitrate) encoded. You can use advanced settings ( ) for each file entry to adjust the compression. The following options are available:

Cut audio from - to: Cut the resulting MP3 at the beginning and / or the end. The start / end timestamp must be formated as HH:MM:SS.
Audio Bitrate: Set the target bitrate range. We recommend to use a variable bitrate (VBR) because the bitrate will be automatically adjusted to the actual needed bitrate. If you want, you can select and set a constant bitrate (CBR) here.
Channels: If you want to get mono instead of stereo output, you can set it here.
Frequency: The sample rate for the output MP3. Normal set up is 44100 Hz.
Audio Normalization: If your input audio is too quiet (or too loud) you can boost the volume here. The 'auto' option allows you to normalize automatically.
