THE WORKFLOW, EXPLAINED

How to compress audio to target size

A target-size calculator estimates the encoding bitrate from playback duration. MP3 and AAC encoders can add metadata and container overhead, so the result is an estimate rather than an absolute byte-exact limit.

  1. Upload audio and inspect its duration and input size.
  2. Choose the target MB, codec, mono/stereo mode and bitrate ceiling.
  3. Export, inspect the resulting file size and listen to verify clarity.

Output size is driven by bitrate and duration

A target-size calculator estimates the encoding bitrate from playback duration. MP3 and AAC encoders can add metadata and container overhead, so the result is an estimate rather than an absolute byte-exact limit. This workspace uses browser-local media codecs for output creation. First-time processing may require downloading a sizable WebAssembly engine; conversion speed, available encoders and supported formats depend on the device, source file and browser. Review the exported video or audio before relying on it professionally.
