Decoding audio & generating waveform...
Turn any song, voice memo or sound effect into a ringtone in your browser. Drop in an MP3, M4A, WAV, OGG, FLAC or AAC file, and the tool loads it on a zoomable waveform with a 30-second selection and a 2-second fade-out already in place. Move the selection to the part you want, press play to check it, and export as M4R for iPhone or MP3 for Android. Trimming, fades and MP3 encoding happen on your device; only the M4R conversion sends the already-cut 30-second clip to our server, never the whole file.
This is the ringtone preset of the KlipTools Audio Trimmer, set up so the first click is the right one. Everything the trimmer can do is still here: zoom, drag handles, exact time inputs, undo, volume and normalize.
An M4R file is AAC audio in an MP4 container with the .m4r extension. iOS uses that extension to sort a file into the ringtone list rather than the music library, so renaming an MP3 does not work: the audio inside has to be AAC. Ringtones can be at most 40 seconds long and text tones 30 seconds, which is why the preset cuts 30 seconds. Android is far less picky: it plays MP3 ringtones directly and has no length limit.
MP3, WAV, OGG (Vorbis), M4A (AAC), FLAC and AAC, plus anything else your browser can decode. Output is M4R (iPhone), MP3 at 128, 192 or 320 kbps (Android and everything else) or WAV if you want a lossless clip for further editing.
Yes. There is no account, no watermark and no limit on how many ringtones you make. The tool runs in your browser; only the M4R conversion uses our server, and the clip is discarded after the response.
Up to 40 seconds for a ringtone and 30 seconds for a text or alert tone. The preset cuts 30 seconds so the same file works for both. Longer files are rejected when you sync them to the phone.
Save the M4R to the Files app, open it in the free GarageBand app for iOS, drag it onto a track, then choose My Songs, long-press the project, Share, Ringtone, Export. It appears under Settings, Sounds & Haptics, Ringtone. GarageBand trims projects to 30 seconds on export, so cut the clip here first.
Mac: connect the iPhone, open Finder, click the iPhone in the sidebar and drag the .m4r file onto it. Windows: install iTunes for Windows or the Apple Devices app, select the device, open Tones under On My Device and drag the file into the list. No full sync is needed.
Yes. Any format your browser can decode loads on the waveform, including M4A, WAV, OGG, FLAC and AAC. The output format is independent of the input, so an M4A becomes an M4R for iPhone or an MP3 for Android with the same steps.
Yes. Choose the Android preset or the MP3 format. Android accepts MP3 ringtones directly with no length limit, so you can also make a longer clip if you prefer. Copy the file to the Ringtones folder or add it from Settings, Sound, Phone ringtone.
Yes. For an iPhone text tone select up to 30 seconds (3–5 seconds is typical) and export M4R; install it the same way and pick it under Text Tone. For Android notifications and alarms, export MP3 and add it from the Notification sound or Alarm sound screen in Settings.
Either the file is longer than 40 seconds, or it is not a real M4R. Renaming an MP3 to .m4r does not convert it. Re-export from this tool with the iPhone preset, then transfer it again through GarageBand, Finder or iTunes. Copying the file into iCloud Drive or the Files app alone does not install it.
Trimming, fades, volume, normalization, and WAV and MP3 export happen entirely in your browser; the original file never leaves your device. The M4R export sends only the trimmed 30-second clip to our server for conversion, and nothing is kept after the file is returned.
Yes. The Audio Trimmer is the same engine without the preset applied on load: it defaults to WAV output and keeps the full track selected, which suits cutting songs, podcasts and voice memos rather than ringtones.
Use this free audio trimmer when you need to cut a podcast clip, remove silence from a voice memo, create a ringtone, or trim music for a short-form video. Because the tool runs in your browser, your file stays on your device and you can preview the exact section before exporting.
A good workflow is simple: upload the file, play it once, set your start and end points, preview the selected range, then export in the format you need. If you are trimming for social content, keep the section tight and remove long intros, dead air, and repeated phrases.
Does it upload my audio? No. The trimming workflow is browser-based for privacy and speed.
Which formats are supported? Common formats like MP3, WAV, OGG, M4A, FLAC, and AAC work best.
