Your files never left your device
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
A custom ringtone is quick to make: drop a song, find the best spot in the preview, enter the start second - and you have a 20 to 40 second clip, optionally with a smooth fade so the tone never starts or ends abruptly.
The iPhone expects ringtones as M4R - technically a normal MPEG-4/AAC file with a different extension, at most 40 seconds long. That is exactly what this tool produces, directly in the browser. For Android and everything else, M4A and uncompressed WAV are available.
As with every gottrix tool, the music file never leaves your device: only the chosen window is decoded (even from a long live recording), trimmed, faded and encoded locally.
| Input formats | MP3, WAV, M4A, AAC, OGG, OPUS, FLAC |
|---|---|
| Auto-conversion | MP4 |
| Output formats | M4R, M4A, WAV |
| Batch processing | No |
| Processing | Locally in your browser (WebCodecs) |
| File upload | None |
Limitations: At most 40 seconds (iPhone rule). You then transfer the M4R to the iPhone yourself (Finder/iTunes or the GarageBand app) - no browser can install ringtones directly, true of every web tool. M4R/M4A need the browser WebCodecs AAC encoder (current Chrome/Edge/Safari); WAV works everywhere. Compressed inputs need WebCodecs decoding.
| Format | Device | Max. length |
|---|---|---|
| M4R | iPhone | 40 seconds |
| M4A | Android/general | 40 seconds |
| WAV | uncompressed, everywhere | 40 seconds |
No. Cutting, fading and encoding all happen locally in the browser.
Download the M4R and drag it onto the iPhone via Finder (macOS) or iTunes (Windows) - or import it through the GarageBand app. It then appears under Settings > Sounds.
The iPhone only accepts ringtones up to 40 seconds; 30 seconds is the usual standard.
A short fade-in (0.3 s) and a longer fade-out (1.5 s), so the clip never starts or cuts off hard mid-beat.
Yes: choose M4A or WAV - Android accepts both directly as ringtones (put the file in the Ringtones folder or pick it in settings).
Yes, the whole trim runs in the mobile browser - you do not need a computer for that. Only the last step (transferring the M4R file to the iPhone) traditionally needs a computer with Finder/iTunes; to avoid that, use the GarageBand app directly on the iPhone instead.
Many ringtone apps require a subscription, show ads, or make you buy the music through the app itself. Here you bring your own song, everything stays free and local in the browser - no install.
