Write out the decoded samples untouched instead of compressing the sound again
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.Many online cutters decompress a file, cut it, and compress it again, which throws away a little more of the sound every time. Nothing is compressed here: the samples the browser decoded are written straight into a WAV, so what comes back matches what went in. The honest catch is the file size, which is roughly ten megabytes a minute in stereo, and the page shows the figure before you press anything.
Drop the audio file onto the page and mark the part to keep with the waveform handles.
Choose WAV with Depth 16-bit to write the decoded samples untouched, or MP3 for an MP3 source to copy its frames.
Pick 24-bit only if the source was recorded at 24-bit; otherwise it makes the file larger with no gain.
Press Cut this clip, then Download; the note above the button says how the file was saved.
Mark the parts of a recording worth keeping, press the button, and each one arrives as its own file. The file is read by this page on your own device; no copy is sent anywhere, no account is asked for, and nothing is stamped on the sound.
WAV is always available: the decoded samples written out untouched, exact but large, about 10 MB a minute in stereo. M4A is AAC in an MP4 container, encoded by the browser's own WebCodecs encoder at 256 kbps, and about a fifth of that size. Chrome, Edge and Safari 16.4 or later have that encoder; where a browser lacks it, the page says so before the button rather than failing after it. MP3 comes out only when an MP3 went in, because no browser can encode MP3 and the free encoders carry a copyleft licence this site will not ship. The original frames are copied instead, so the sound is untouched, but each cut lands on a 26-millisecond frame edge and cannot fade.
A cut in decoded audio can land anywhere. Each clip begins and ends where you put it, to the nearest sample, with a five-millisecond fade at each edge so the cut does not click. Set the fade to zero for the sample-exact edge.

Drop the MP3 on this page and the browser decodes it on your own device, with no request to any server. Drag the two handles across the part you want and press the cut button. The clip is written in the page and saved straight to your downloads folder, so no copy of the recording ever exists elsewhere.
Browsers can decode an MP3 but none can encode one, and the free MP3 encoders carry a copyleft licence this site will not ship. So WAV is the default, written straight from the decoded samples. From an MP3 source, MP3 is offered by copying its original frames, and M4A is offered wherever the browser has an AAC encoder.
Nothing is compressed again, so no. The browser decodes the file once, the samples inside your clip are copied into the WAV exactly as they were decoded, and the file is saved. Quality already lost when the original was compressed cannot be recovered, but this step adds no further loss of its own.
Audio kaise cut kare: add the file to this page, drag the two handles to the part you want, and press the cut button. No app, no account and no upload is involved, because the browser does the work on your own phone or laptop. The clip is saved as a WAV file.
