How To Use It
Upload your audio file, pick an output format, then adjust the compression settings shown on the page before starting the task and downloading the result.
For audio, you can reduce size by changing bitrate, sample rate, and channels. Speech-focused files usually tolerate lower settings better than music.
Helpful Notes
Music, podcasts, and lessons often work well at 128k or 192k. If file size matters more than fidelity, speech recordings can often use lower values or mono output.
Always compare the exported result before replacing the source file so you do not lose too much detail, clarity, or playback quality.
FAQ
Which setting should I adjust first for audio compression?
In most audio workflows, bitrate is the first setting to adjust. You can then fine-tune sample rate and channels if you still need a smaller result.
Are files uploaded to a server?
No. The compression workflow runs in the browser, which is helpful for privacy-sensitive media and internal assets.
