What it does
You have a 1:24 recording and you need only the first 30 seconds. This tool does exactly that: mark where the section starts and ends, and download that piece.
No account, no watermark, no daily limit.
What makes it different from other cutters
Almost every audio trimmer that shows up in search works the same way: you hand over the file, it is uploaded to their server, processed there, and handed back as a download link. A copy of your audio now sits on a machine you do not control, under someone else’s retention policy.
That does not happen here. The browser decodes the audio with the Web Audio API, slices the samples, and builds the finished file on your own machine. No network request ever contains your audio.
The check is easy: load the page, go offline, and cut a file. It still works.
Setting the section
The time fields accept several notations, because nobody writes them the same way:
| You type | It reads as |
|---|---|
0:30 |
30 seconds |
30 |
30 seconds |
1:24 |
84 seconds |
0:05.5 |
5.5 seconds |
1:02:03 |
1 h 2 m 3 s |
You can also click straight on the waveform — whichever edge is nearer jumps to where you clicked. That is the fast way to find the silence between two sentences.
About the output format
Output is WAV, uncompressed. That is a deliberate choice.
An MP3 does not store sound; it stores a compressed approximation of it. Cutting one means decompressing it first, and saving it back as MP3 would mean compressing again — adding a second generation of loss on top of the one it already carried, and requiring an extra ~150 KB encoder to be downloaded.
WAV avoids both. The clip sounds identical to the source and there is nothing extra to fetch. The cost is size: roughly 5 MB per 30 seconds in stereo.
You can choose 16-bit or 24-bit. 16-bit is right nearly always — it is CD depth and what every player expects. 24-bit only matters if you are taking the clip into another editor afterwards.
Limits worth knowing
- 50 MB per file. Because the work happens in your browser, anything larger risks exhausting the tab’s memory.
- Your browser decides the formats. Which containers open is up to the browser, not this page. FLAC and M4A work in most current browsers, but not all of them.
- One cut per file. You can keep a single continuous section, not stitch several pieces together.
