Add a track
Choose an audio file from your phone or computer. Ringtonz reads it in your browser and draws a waveform to help you find the right moment.
A little trim. A lot more you.
Keep the moment.

Opening your audio…
Drag the waveform handles, use the arrow keys, or enter exact start and end times. WAV-to-WAV cuts without fades preserve the original samples when the source is a supported WAV file.

Choose the cut
Drag the start and end handles, move them with the arrow keys, or enter exact times. Play the selection before exporting.
Export your ringtone
Save the clip as MP3 or WAV. Set the MP3 bitrate and add a short edge fade when you want smoother starts and endings.
Export formats

MP3
Easy to share and set as a ringtone
MP3 is compact and widely supported by phones and music apps. Choose 192 kbps for a balanced default, or a higher bitrate when you prefer it.
WAV
Uncompressed PCM audio
WAV is useful for editing or when you want uncompressed output. A direct WAV-to-WAV cut without a fade can preserve the original PCM samples and bit depth.
Large recordings
Designed to handle long WAV files
Ringtonz checks supported PCM WAV files in small pieces rather than decoding the whole recording just to draw the waveform. That makes long WAV recordings practical to inspect and cut. Compressed formats such as MP3, FLAC, AAC, OGG and M4A must be decoded as a whole by the browser, so very large files may exceed your device’s available memory.
01
Streamed WAV inspection
The editor samples small windows from supported WAV files to create the waveform, instead of reading the whole audio payload into memory.
02
Direct lossless cuts
For supported WAV input, WAV output and no edge fade, Ringtonz copies the selected bytes and writes a matching WAV header without recoding the audio.
03
Clear memory limits
Compressed audio requires full decoding. The app uses a cautious file-size limit and reports a readable error when a file is too large to open.
Local processing

No audio upload
Your selected audio is read and processed in your browser. The result is assembled locally and offered as a download rather than sent to a conversion server.
Useful for private clips
Trim voice notes, interview clips, personal recordings or music files without uploading their contents to a third-party audio service.
FAQ
Frequently asked questions
Which audio formats can I trim?
Ringtonz tries to open audio formats supported by your browser, commonly MP3, WAV, FLAC, AAC, OGG and M4A. Supported PCM WAV files can use the streamed editing path; compressed formats are decoded by Web Audio.
Does trimming reduce audio quality?
A supported WAV-to-WAV cut without a fade copies the selected audio samples without re-encoding. Exporting a compressed source to MP3 re-encodes it, and applying a fade to a WAV selection uses the PCM export path.
Why might a large MP3 fail to open?
Browsers generally decode compressed audio into full in-memory sample buffers. Long or high-resolution recordings can exceed a phone or computer’s available memory. Supported PCM WAV files can be inspected in streamed mode instead.
Can I preview only the selected section?
Yes. Use the play control to preview from the selected start time; playback stops when it reaches the selected end time.
Does Ringtonz upload my audio?
No audio content is uploaded by the trimming workflow. The MP3 encoder library is loaded on demand from a CDN if you choose MP3 export; your audio remains on your device.
Is Ringtonz free?
Yes. Ringtonz is free to use in your browser and does not require an account.
