Why use this audio trimmer

Cut to the exact second

Enter a start time and an end time in hours, minutes, and seconds. The clip you keep starts and ends exactly where you set it, with no need to drag a handle.

Keeps the format you uploaded

An MP3 comes back as an MP3 and a FLAC comes back as a FLAC. Nothing else has to change: not your player, not your podcast host, not your ringtone folder.

Works in your browser

No download and no sign-up. Drop in an audio file and trim it on any device, from a desktop to a phone, over an encrypted connection.

Trim audio online

Trimming keeps one continuous stretch of a recording and drops everything before and after it. You set a start time and an end time. The result is only the span between them. The count-in before the first verse is gone, the dead air at the end is gone, and the chorus stands on its own.

That is what most people actually need audio for. A 30-second ringtone out of a full track, or a quotable minute out of an hour-long podcast. The useful half of a voice message, or a short sample to drop under a video. A lecture recording that no longer starts with 5 minutes of chairs scraping.

Versatile tool to trim audio online

Audio trimmer or audio cutter, what is the difference?

In everyday use there is none, and search results agree: tools that call themselves audio cutters do exactly what this audio trimmer does. You mark a start and an end, and you keep the section between them. If you came here looking for an MP3 cutter, you are in the right place.

Where people do draw a line, it is about direction. Trimming shaves time off the outside of a file: lose the first eight seconds, lose the last minute. Cutting can also mean taking a piece out of the middle. To do that here, run the file through twice. Set an end time where the unwanted part begins, then set a start time where it ends. You get the two halves you want to keep.

An MP3 trimmer that is not only an MP3 trimmer

MP3, WAV, FLAC, M4A, AAC, OGG, OPUS, WMA, AIFF, M4R, and MMF all go in. By default the trimmed clip comes back in the format it arrived in. There is no forced detour through MP3 just to shorten a file, which makes this usable on lossless material.

Quality follows from that. WAV, FLAC, and AIFF are lossless, so trimming them costs nothing measurable. MP3, AAC, OGG, and OPUS are lossy. They have to be re-encoded around the new start and end points, which costs a small amount of detail. At the bitrates ordinary music, podcast, and voice files use, it is not something you will hear. Keeping the original format is the most efficient option either way.

Audio trimmer FAQ

How do I trim an audio file for free?

Upload the file above, set a start time and an end time in the settings, and start the job. The audio trimmer is free, runs in your browser, and does not ask you to create an account first.

What is the difference between an audio trimmer and an audio cutter?

In practice, none. Both names describe marking a start and an end and keeping what lies between them. This page works as an audio cutter and as an audio trimmer, whichever term you searched for.

Can this audio trimmer cut MP3 files?

Yes, MP3 is the most common input here, and the trimmed clip comes back as an MP3. WAV, FLAC, M4A, AAC, OGG, OPUS, WMA, and AIFF are handled the same way.

Does trimming audio reduce the quality?

Trimming a lossless file such as WAV, FLAC, or AIFF changes nothing at all. Lossy formats such as MP3 or AAC are re-encoded, which costs a small amount of detail. At the bitrates normal music and podcast files use, the difference is not audible.

How do I cut a section out of the middle of a track?

Trim the file twice. The first run ends where the unwanted section starts, the second run begins where it stops. You are left with the two pieces you want, and the middle is in neither of them.

Can I trim several audio files at once?

Yes. Add more than one file and they are trimmed in the same run. Each one comes back separately, so you do not have to repeat the upload for every clip.

Can I trim audio on my phone?

Yes. Open this page in your mobile browser and pick the recording from your phone or from cloud storage. There is no app to install on Android or iOS.

Is there a file size limit?

Free trimming covers everyday music, podcast, and voice-message files. If you regularly work with long recordings, a subscription raises the limit and removes the queue.
