Plus, you can also convert online audio & video files to MP3 format. Simply use the URL upload method and enter any audio or video file URL.

Use our Advanced Settings to perfectly convert any file to MP3 format. You can adjust the following settings:

Audio Codec - Select the MP3 (MPEG-1 Audio Layer III) codec for the best MP3 quality. Doing so will also unlock most of the following advanced options.

Audio Rate Control - You can either use VBR (Variable Bit Rate) or CBR (Constant Bit Rate). Choose VBR when you want to optimize file size and quality (the encoder will use a higher bitrate for complex content while saving bitrate from areas that do not need as much data. However, VBR may also introduce playback/seek issues due to the variability in bitrate. Use CBR when you want a constant bitrate throughout.

Audio Bitrate - Weather you use CBR or VBR, choose the highest bitrate you can afford (at the expense of a bigger file size) for the best audio quality.

Audio Sample Rate - Sample rate defines how many times per second a sound is sampled. For high-quality audio, we recommend either 44100 Hz (CD Quality) or 48000 Hz (DVD Quality)

Trim Settings - Use these options to trim your output audio file

Fade In/Out - Use the fading-in/out effect for a more pleasant listening experience.
