A smaller audio file. A deliberate trade-off.
Reduce audio file size using an encoded format and an appropriate bitrate, then compare the requested output with the source.

- 01
Upload your source
Sign in and upload a local file. Inspection checks the streams and duration.
- 02
Adjust the operation
The relevant settings section opens after inspection. Review the starting values below.
- 03
Preview and review
Render a short processed preview where applicable, then save and review the full task.
- 04
Convert and download
Follow background processing and download the validated output.
Compress audio file settings
Choose the operation here and it stays selected through registration or sign-in. Upload and inspect your source to open its settings. Starting values are editable; check them against your file before submitting.
Audio output
MP3 is the initial profile.
Bitrate
Starts at 128 kbps constant bitrate.
Channels / range
Choose compatible channel settings and trim unwanted duration.
What to check before exporting
Lossy encoding trades signal detail for size. Re-encoding an already compressed file can add artifacts. Audio Dynamics is a separate operation for loudness peaks; it is not a file-size control.
Choose a compatible output profile and review the source streams, selected range and final settings. Processing uses structured controls, and incompatible combinations are rejected before queueing. Download the requested result when final validation completes.
A real workspace. A result you can inspect.
This actual product screenshot shows source playback, range selection, an uploaded-audio area and encoding settings. It illustrates the shared converter; your operation opens its own relevant controls after inspection.
A processed preview creates a separate short task. It covers the first ten seconds of your range at up to 360p in a compatible format. Image and subtitle exports still need inspection of the requested final download.

Questions about this workflow
Will converting to WAV make the file smaller?
Usually not for a compressed source. Uncompressed WAV stores decoded samples and can be much larger.
Can I close the tab while processing?
Yes. Submitted conversion tasks run in the background. Return to your account to check progress and download results before the retention period ends.
What are the upload and storage limits?
Current source limits are 2 GiB and two hours per file. Files have a 72-hour retention period; task, collection and resource limits also apply. The workspace shows the applicable limits. Free and Pro currently share feature access.
