Trim audio
Drop a song, a voice memo or a video, pick the parts on the waveform or type their times, then keep them or cut them out. One kept stretch in the same format is copied without re-encoding. Nothing leaves your device.

How it works
- Drop an audio file, or a video, anywhere on this page.
- Drag across the waveform or move the two handles, or type the start and end; add more parts if you need them, and press play to hear the outlined one.
- Choose Keep the parts or Remove the parts, add fades if you want, and press Trim audio.
Ringtones, voice memos and podcast clips
The typical jobs are a 30-second ringtone from a song, a voice memo with the first minute of silence gone, a quote cut out of a podcast, or the sound of a video reduced to the part that matters. Drop the file, drag across the waveform or type the times, and listen to the outlined part before cutting. A single kept stretch in the file's own format is copied without re-encoding, so it is quick and loses nothing.
Fades and joins
Fade in and Fade out go up to 10 seconds each and stop a clip from starting or ending abruptly, which matters for ringtones and loops. When several kept parts are joined, Crossfade at joins overlaps them by up to 2 seconds; leave it at None and the lengths add up exactly. Removing a part joins what is left with a short 10 ms crossfade so there is no click. Any fade or join re-encodes the audio at the source's bitrate; choose WAV or FLAC to keep every sample.
Batches, formats and limits
Up to 20 files of up to 2 GB each take the same cuts in one run, useful for a series of recordings with the same intro to remove. The result can keep its format or become MP3, WAV, M4A, Opus or FLAC; M4A needs a browser with an AAC encoder, which Firefox lacks. Everything is read, cut and written on your device, and the network meter under the result stays at zero.
Why people use it
Free, no account
Every tool is free, with no sign-up, no e-mail address and no limit on how often you use it.
Your files stay on your device
The browser opens the file and processes it in memory, on your device. Nothing is uploaded, so nothing can be kept, leaked or looked at.
No watermark
The result is yours as it is: no watermark, no branding, no trial version.
Any device
A phone, a tablet or a computer with a current browser is enough: no app to install, no software to update.
Works offline after the first visit
The browser keeps the pages and their engines, so a tool you have opened once keeps working without a connection.
Open-source engines
The code that does the work is open-source software, named on the Licences page, running as WebAssembly in your browser.
Why it is private
Everything you type or drop here is handled by your browser, on your device. Nothing is uploaded. To verify, open your browser's developer tools, go to the Network tab, and use the tool: you will see no request carrying your data.
While a file is being processed, the counter under the result shows the page's network traffic: 0 requests and 0 B for your data.
How to check it yourself, step by step
What you can check yourself
Open your browser's developer tools on the Network tab before you drop a file: while the tool works you will see no request carrying your data, and the counter under every result shows the page's own measurement.
The site sets no cookies, so there is no cookie banner. Anonymous usage counts and error reports without file names are the only things that leave the page, as the privacy policy describes.
Every change goes through thousands of automated tests in three browser engines, including a guard that fails a test if a single byte of a file leaves the page.
Frequently asked questions
- Is the cut lossless?
- When you keep one stretch, add no fades and leave the format on Same as the file, the audio frames are copied as they are: no re-encoding, no loss, and the result says 'Copied without re-encoding'. A compressed frame lasts a few hundredths of a second, so the cut can move by up to about 0.1 s to the nearest frame. When it cannot be copied, the audio is re-encoded at the source's bitrate and the result says so. A WAV is cut to the exact sample, without loss.
- Can I keep or remove several parts?
- Yes, up to 20. Add a part for each piece and set it on the waveform (the handles move the outlined part) or type its times. With Keep the parts they are joined in time order, with an optional crossfade at each join (none by default, so the lengths add up exactly); with Remove the parts they are cut out and what is left is joined with a 10 ms crossfade so the joins do not click. Any join decodes and re-encodes the audio, in the same format unless you choose another.
- How do I find the exact spot?
- Click the waveform to move the cursor and play from there; zoom with Ctrl + wheel, a pinch or the + button. Pause where the cut goes and press Start at cursor or End at cursor. The handles also move with the arrow keys: 0.1 s, or 1 s with Shift.
- Can I cut the sound of a video?
- Yes. Drop an MP4, MOV, WebM or MKV: its audio track is cut and saved as an audio file (M4A for AAC, OGG for Opus); the picture is left out.
- Which files and lengths work?
- Any audio your browser can decode: MP3, WAV, M4A and FLAC everywhere, OGG and Opus in most browsers. M4A, Opus and FLAC output need the browser's own encoder (Firefox has no AAC encoder). A copied cut handles long files; fades or removing a part decode the audio into memory, about an hour and a half on a computer and around five minutes on a phone.
- Is my file uploaded?
- No. It is read, cut and written in your browser; the network meter under the result stays at 0 B.
- Can I make a ringtone?
- Yes. Keep a stretch of up to 30 seconds, add a short fade out and save as MP3 or M4A. Android takes the file directly; an iPhone needs it imported through a computer or a ringtone app.
- Can I trim audio on my phone?
- Yes, in the browser. A plain cut handles long files; fades and removed parts decode the audio into memory, which on a phone covers a few minutes.
- Can I trim a WhatsApp voice note?
- Yes. Save the note as a file (Opus in an OGG container), drop it here and cut it; most browsers decode Opus, and you can save as MP3 to play it anywhere.
- Can I cut the same part from many files?
- Yes, up to 20 files per run. The parts you set apply to every file in the list, which is handy for recordings that all share the same intro.
