How to
# How to trim audio online for free
Published November 11, 2026 .
Open Audio trimmer, drop a WAV, MP3, M4A, FLAC, or OGG, and type a start and an end in seconds. Click Cut audio. WAV is cut in the browser with a 10 ms fade on each end. MP3 is libmp3lame at 192 kbps and does not add that fade. The file is not uploaded. The limit is 15 minutes or 80 MB.
The tool for this is Audio trimmer . You keep one region of a file you already have. The page does not upload it, and it does not take a video. Use your own recordings, or recordings you have the rights to.
The result plays in the player under the button. This page does not add a separate Download button. Closing the tab drops that file. Leave the tab open until you have saved it, if your browser offers a save on the player.
## Steps
- Drop a WAV, MP3, M4A, FLAC, or OGG Open Audio trimmer and drop the file. The hint lists WAV, MP3, M4A, FLAC, or OGG. The picker also includes .aac. It does not list video. The whole file has to stay under 15 minutes or 80 MB.
- Type the start and the end Start and End are seconds. The inputs step by 0.1, so 12.4 and 18.9 are valid. Dropping a file sets Start to 0 and End to the duration the browser reads, or to 0.2 seconds when that read is not a number. The end has to sit after the start. The file card seeks its player to the start time you typed.
- Choose WAV or MP3 The menu is labeled Download as, and it opens on WAV. WAV is decoded in the tab, sliced to the region, given a 10 ms fade at each cut, and written as 16-bit PCM at the decoded sample rate and channel count. That path never loads ffmpeg. A slice that is too short for two fade frames skips the fade. MP3 encodes the same region with libmp3lame at 192 kbps. The command is -ss at your start and -to at your end. It does not add the 10 ms fade. The first MP3 job downloads ffmpeg, about 31 MB. Later MP3 cuts in the same tab reuse it.
- Click Cut audio The button reads Cut audio, then Cutting. A WAV finish says Cut to and the new length. An MP3 finish says MP3 ready and the file size. The player under the button is the new file. There is no separate Download button. The source file is unchanged. Closing the tab drops the result.
## WAV or MP3 on the trimmer
## Where to put the cut
Leave a little air before a spoken word. A cut exactly on the consonant clicks. The WAV fade is 10 ms, which softens the splice. It does not hide a cut that lands in the middle of a word. Type the times you measured. 12.4 means 12.4 seconds, not a rounded 12.
Use WAV when the next step is another tool on this site. A second MP3 encode adds another generation of loss. Use MP3 when you need a smaller file to send. The bitrate is fixed at 192 kbps. This page does not offer 128 or 320.
## A ringtone, a format change, or a video
Ringtone maker is the short-hook page. You set a start and a length, not a start and an end. Forty seconds is the cap. It encodes AAC at 128 kbps, fades 80 ms at the head and the tail, and the download button saves an .m4r file. It can take a video and discard the picture. The trimmer does not do that job.
Audio converter changes the whole file to WAV, MP3 at 192 kbps, M4A, FLAC, or OGG. It does not cut a region. A video dropped there loses the picture. The same 15 minute and 80 MB limit applies. Use it when the trimmer cannot read the container, then trim the WAV.
A video is not a trimmer input. Video to MP3 pulls an MP3 at 128, 192, 256, or 320 kbps and discards the picture. Files over 250 MB are refused there. The walkthrough is how to extract audio from a video . Trim the MP3 after that, when you only need a section of the soundtrack.
## After the cut
Trimming does not remove noise and it does not split a song. Vocal remover writes a vocals WAV and an instrumental WAV, up to 8 minutes. Bring a stem back to the trimmer if you only want part of it. The vocal page can also take a video.
Steady hiss on a voice is a different job. The walkthrough is how to remove background noise from audio . That page is a poor fit for music. It does not shorten the file.

## FAQ
- How do I trim audio online for free?
Open Audio trimmer, drop a WAV, MP3, M4A, FLAC, or OGG, type a start and an end in seconds, and click Cut audio. The cut runs in the browser. Nothing is uploaded. The limit is 15 minutes or 80 MB.
- How do I cut an MP3 file without uploading it?
Choose MP3 under Download as. The page trims with ffmpeg in the tab at 192 kbps. The first MP3 job downloads about 31 MB of ffmpeg. Later cuts in the same tab reuse it. The file is not posted to a server.
- How do I shorten an audio file to exact times?
Type the start and the end in seconds. The fields step by 0.1, so 12.4 is 12.4 seconds. The end has to be after the start. Dropping a file fills the end with the duration the browser reads.
- Does the trim fade the edges?
On WAV, yes. Each cut gets a 10 ms fade. A slice that is too short for two fade frames skips it. The MP3 path does not add that fade. Ringtone maker is the page with an 80 ms fade, and it caps the length at 40 seconds.
- Should I download WAV or MP3?
WAV keeps the decoded sample rate and channel count and avoids another lossy encode. Use it when another tool on this site is next. MP3 is the smaller file, fixed at 192 kbps. The player under the button is the new file. This page has no separate Download button.
- Can I trim the audio out of a video here?
No. The trimmer does not list video. Extract an MP3 with Video to MP3 first, then trim that file. Ringtone maker and Audio converter can take a video, and both discard the picture.
Files stay on this device.
Free tools never upload the file you open. Studio is the only paid part of the site, and the only place a prompt is sent to a video model.
