About this tool
Shrink an audio file’s size by re-encoding it at a lower bitrate — useful for email attachments, storage limits, or faster uploads, with a choice of bitrate to balance size against quality.
What bitrate should I choose?
128 kbps is a reasonable balance for most speech and music; go lower for smaller files or higher to preserve more quality.
What format do I get back?
An MP3 file at the chosen bitrate.
Is my audio uploaded anywhere?
No, compression happens entirely on your device. A one-time ~30 MB processing engine downloads the first time you use a video or audio tool.
