Trimming your audio...
This tool cuts an audio file down to a specific section — set a start and end point using the visual waveform and sliders, preview the selected portion, and download just that part as a new audio file. Everything outside your selected range is removed.
Trimming happens entirely in your browser using the Web Audio API — your file is never uploaded to a server.
The waveform gives a visual representation of the audio's volume over time — taller sections represent louder parts, while flat sections often indicate silence or quiet passages. This makes it easier to spot where to cut: for example, if you're removing silence from the start of a recording, you can visually identify where the waveform "begins" and set your start point there, rather than guessing based on time alone.
The "right" trim point depends a lot on what the clip is for. If you're removing dead air from the start or end of a voice recording, trimming as close as possible to where speech actually begins and ends gives the tightest result — though leaving a fraction of a second of buffer avoids cutting off the very start of the first word. If you're extracting a highlight or quote from a longer recording, it often helps to include a little context on either side — a sentence starting mid-thought can be confusing out of context, so trimming to include the start of a complete sentence or phrase, even if it means a slightly longer clip, usually makes for a more usable result. For creating a short clip for a ringtone or sound effect, the considerations are different again — see our Ringtone Maker for a tool specifically designed around that use case, including a fade-out.
For long recordings — lectures, meetings, multi-hour streams — visually scanning the entire waveform to find a specific moment can be slow. If you have a rough idea of the timestamp you're looking for (for example, from notes taken during the original recording, or from a video player's timestamp if the audio was extracted from a video), jumping close to that point first and then fine-tuning using the waveform and preview is much faster than scrubbing from the beginning. It's also worth trimming in stages for very long files — cutting a rough, larger section first, then trimming that smaller section more precisely — rather than trying to set both the start and end points with high precision across a very long timeline in one step.
The trimmed clip is exported as a WAV file, preserving the exact audio quality of the selected section with no additional compression. If you need a smaller file afterwards, run the result through our Audio Converter to convert to MP3, or Audio Compressor to reduce file size directly.
Yes, you can play back just the selected portion to confirm it's correct before exporting.
The trimmed clip is exported as a WAV file at the original audio quality. Use the Audio Converter afterwards if you need MP3.
Files up to 30MB are supported. Longer files take more memory to process in your browser.
Yes, after downloading one trimmed section, you can adjust the selection and trim again from the same uploaded file.
No, trimming happens entirely within your browser.
