Cutting without re-encoding — why it matters
Most online cutters decode your audio and encode it again, losing a little quality every time — cut an MP3 twice and the artifacts start to ring. This tool copies the original stream instead: frames outside your selection are dropped, frames inside are kept byte-for-byte. The result is instant even on an hour-long recording and sounds exactly like the source, because it is the source.
Precision is one audio frame — about 26 milliseconds for MP3, far finer than any ear can notice. Play the file right on the page, note the times, type them in as 1:23 or plain seconds, and cut. Ringtones, podcast fragments, voice memos — all without the file ever leaving your device.
Frequently asked questions
Does trimming reduce quality?
No — the stream is copied, not re-encoded. The trimmed part is byte-identical to the original recording.
Which formats are supported?
MP3, WAV, M4A/AAC, FLAC, OGG and Opus. The output keeps the same format as the input.
How precise is the cut?
To the nearest audio frame — roughly 26 ms for MP3. For a ringtone or podcast cut that's imperceptible.
