Make a WAV recording much smaller by saving it as an MP3.
Convert WAV to MP3 →WAV stores uncompressed audio, which is why a few minutes of recording can run to tens of megabytes. Converting to MP3 usually makes the file a fraction of the size, which helps with email, messaging and upload limits. The tool uses a high-quality variable-bitrate MP3 setting, so speech and music still sound natural, but MP3 is lossy and the conversion cannot be undone. Keep the WAV if you still plan to edit or master it. Files must be under 100MB and 5 minutes.
Choose your WAV audio file from your device. Works with any device - desktop, mobile, or tablet. No account or registration required.
Our tool re-encodes your WAV file as a smaller MP3. Your file is sent to our cloud processor, which does the work for you, so there is nothing to install or configure.
