Keep only the exact section of audio you need
The audio trimmer is useful for removing silence or mistakes at the beginning and end of a recording, or saving one useful section from a longer track. After selecting a file, use the waveform and playback controls to set precise start and end points.
The trimmed section is created as a new file in your chosen format, and the original file is never changed. Short fade-in and fade-out effects can also soften abrupt cuts.
Find sections with the waveform
To keep 2:10 through 2:40 from a ten-minute recording, enter 130 seconds and 160 seconds for an approximately 30-second clip. Each operation keeps one continuous section; it does not remove a middle section and automatically join both sides.
Preview before trimming
Cutting speech by waveform alone can remove an opening syllable or final consonant. Listen around both boundaries and leave a little room. Range preview checks the source section; check fades and output quality again in the generated result.
Fade effects
Fades can soften sudden level changes when music is cut mid-track. They can also lower the start of spoken words, so use them selectively. They do not remove noise throughout the recording or restore cut-off syllables.
Helpful answers before you start
Does trimming change my original audio file?
No. The original remains unchanged, and the selected section is created as a new file. Your source file stays intact after downloading the result.
Can I type the start and end times?
Yes. Enter start and end values in seconds below the waveform. Moving the sliders also updates the time fields.
Can trimming an MP3 affect its quality?
The selected section is re-encoded for precise trimming and format conversion. Even the same output format may change slightly, so choose a higher bitrate or WAV/FLAC when quality is important.
Why can I trim only one file at a time?
Each file needs its own waveform and start and end points. Working on one file at a time helps prevent accidental cuts.
What should I do if the waveform does not appear?
Your browser may not be able to decode that file for preview. Try the latest Chrome or Edge, or convert the file to MP3 or WAV first and then open it again.
