Music Grabber 1.3.8: Save Your Suno Music as WAV or MP3

Music Grabber 1.3.8 is now available on the Chrome Web Store. I built it to make saving music you own or have permission to save more straightforward, with clear progress and local audio processing.

Install Music Grabber from the Chrome Web Store

Save WAV or MP3 beside your songs

In Suno Create, playlists, and Liked Songs, compact controls sit beside completed songs. Play a song from the beginning and allow the full audio stream to load. Once the capture has been decoded and validated, WAV saves the verified audio.

For MP3, choose **Prepare MP3** and follow the conversion progress. When preparation finishes, choose **Download MP3**. Preparing a file does not automatically start a download. This keeps conversion and saving as two explicit steps.

The row controls show capture and conversion progress where you need it, alongside the song, rather than leaving you to guess whether a file is ready.

Studio uses the audio already loaded

Suno Studio has a different workflow. When a supported audio source is already loaded in the editor, the track controls can save that source without replaying or recording it. Tracks with multiple sources offer a source selector.

The saved file contains the original loaded source clip. Timeline trims, time warping, track effects, and a final project mix are not included. Sources that are still unloaded or streaming remain unavailable until suitable audio is ready.

Your audio stays in your browser

Music Grabber processes audio and encodes MP3 locally. It does not upload your captures to the developer or an external service. Temporary captures are held in the tab and disappear when the page is refreshed. Up to three verified captures are retained per tab.

MP3 is a lossy format: converting to MP3 does not improve the quality of the source. Choose WAV when you want the decoded PCM audio rather than another lossy encoding.

Clear progress depends on accurate state

One of the most useful engineering lessons from this project was to distinguish received data from a usable result. A full progress bar alone is not enough: the audio still needs to decode and pass validation before saving becomes available.

Streaming buffers can also discard older ranges while playback continues. Reading only the current buffered ranges can make progress appear to move backward. Music Grabber keeps a merged history of loaded intervals so that progress reflects the capture history, while validation remains a separate readiness check.

The same care applies to downloads. Completing MP3 conversion is different from handing a file to the browser, and handing it to the browser does not prove that writing it to the chosen save location has finished.

Getting started

1. Install Music Grabber from the Chrome Web Store. 2. Refresh the Suno page after installation or an extension update. 3. In Create, playlists, or Liked Songs, play a completed song from the beginning and wait for capture and validation. 4. Save WAV, or prepare MP3 and then download it. In Studio, use the controls for a supported loaded source.

Seeking, interrupted playback, or unsupported player formats may prevent a complete capture. If that happens, refresh the page and play from the beginning. Refreshing clears earlier temporary captures, so save the files you want to keep first.

Use Music Grabber only for music you own or are authorized to save. Supported behavior can change as the underlying site and browser evolve.

Help shape what comes next

I would welcome feedback on the controls, progress display, and your everyday saving workflow. You can suggest another music site through the Music Grabber request form; email is optional.
