How to use this tool
- Drop in an audio file, or click to browse for one.
- Optionally drag the start/end sliders to cut a clip.
- Pick an output format and quality, then click "Convert."
Frequently asked questions
- Is my audio uploaded anywhere?
- No — conversion and cutting happen entirely in your browser using the WebCodecs API. The file never leaves your device.
- Which format should I pick?
- MP3 is the most universally compatible lossy format. WAV and FLAC are lossless (larger files, no quality loss) — good for further editing. OGG is a good open alternative to MP3. AAC and M4A are what Apple devices and most streaming platforms use natively — pick M4A if you specifically need an .m4a file, otherwise AAC is the same audio quality in a smaller, simpler container.
- Can I use this to make a ringtone?
- Yes — trim to the clip you want with the start/end sliders, choose MP3, and download. Some phones require a specific length or format for ringtones, so check your device's requirements.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online audio converters |
|---|---|---|
| Audio ever leaves your device | No — 100% client-side | Yes — uploaded to a server to process |
| Account required | Never | Often, past a certain usage level |
