How do I check the cut before I save it?
Choose a file and the audio trimmer shows its waveform. Drag the two handles, or type the start and end times, then select Play to hear only the part you kept. When it starts and ends where you want, select Trim and save.
Play the selection
Playback starts at your start point and stops at your end point, so you hear exactly what the file will hold.
Play the saved file
After trimming, a player appears under the download button. Listen to the first and last second before you keep it.
What can you do with an audio trimmer?
Most recordings have something to lose at the ends: a count-in, a cough, the silence before someone speaks. An audio trimmer keeps the part that matters.
Make a ringtone or an alert
Trim a song to the 20 or 30 seconds you want to hear when the phone rings. Android takes the MP3; an iPhone ringtone is an M4A of up to 40 seconds renamed to .m4r.
Cut a clip for social media
Keep the best quote from a podcast or an interview for a Reel, a Short, or a TikTok voice-over.
Tidy a voice memo
Remove the fumbling at the start and the phone being put down at the end before you send it.
Pauses in the middle too
The trimmer cuts the ends. To remove long gaps inside a recording, use the silence remover.
Remove silence from audioDoes trimming audio lower the quality?
Not for MP3, WAV, or M4A. The audio trimmer copies the kept part as it is. Other formats are converted once to the format you choose.
| Your file | Saved as | Re-encoded? |
|---|---|---|
| MP3 | MP3 | No, the frames are copied |
| WAV | WAV | No, the samples are copied |
| M4A (AAC) | M4A | No, the AAC is copied |
| FLAC, OGG, Opus, AAC | MP3, M4A, or WAV | Yes, once |
| MP4, MOV, or WebM video | MP3, M4A, or WAV | Only the sound is kept |
Why use EraseNoise as your audio trimmer?
It does one thing, trimming, and it does it on your device.
Nothing is uploaded
The waveform, the playback, and the cut all happen in your browser. A private recording never leaves your device.
No re-encoding for MP3, WAV, and M4A
Many online MP3 trimmers decode and encode the file again, which adds a little loss each time. Here the kept part is copied.
Exact times when you need them
Drag the handles for a quick cut, or type 1:05.3 into the start field to land on a beat.
Free with no account
No sign-up, no watermark, and no limit on how many files you trim.
Why is it faster than an upload trimmer?
There is no upload and no queue. The waveform appears as soon as the file is read, and the cut takes seconds.
No upload wait
An hour-long WAV can be 600 MB. Upload trimmers make you send all of it to keep one minute.
Works on a phone
Open the page in Safari or Chrome, pick the file from Files, trim it with your finger, and save it back to Files.
No editor to open
You do not need Audacity or a DAW project to cut the ends off one file.
Which files can I trim?
Trim audio files up to 2 GB. A trimmed WAV can be up to 60 minutes long.
MP3, WAV, M4A, AAC, OGG, Opus, or FLAC
Songs, podcasts, voice memos, and exports from any app.
The sound of a video
Choose an MP4, MOV, or WebM to trim its soundtrack and save the part you need as audio.
At least one second
The kept part has to be one second or longer.
Files you are allowed to use
This page trims files on your device. It does not download audio from websites.

What else might the file need?
Trimming fixes the ends. These pages fix the rest, and the audio trimmer can hand its result straight to noise removal.
| Job | Use |

| Hum, hiss, fan, or traffic under the voice | Remove background noise from audio |

Is my audio uploaded?
No. The audio trimmer reads the file in your browser and writes the trimmed copy there too. No copy is sent to a server or stored, so refreshing the page clears the result. Download it before you leave.
Frequently asked questions
How do I trim audio for free?
Open this audio trimmer, choose the file, drag the handles or type the start and end, and select Trim and save. It runs in your browser, so it is free, needs no account, and adds no watermark.
Does trimming an MP3 lower its quality?
No. The MP3 frames you keep are copied without decoding or encoding again, so the trimmed MP3 sounds exactly like the original. The cut lands on the nearest frame, about 26 milliseconds.
Can I type exact start and end times?
Yes. Type seconds, minutes and seconds, or hours, minutes, and seconds, such as 1:05.3, into the start and end fields. The handles move to match.
Is my file uploaded?
No. The file is read and the trimmed copy is written in your browser. Nothing is sent to EraseNoise or anyone else.
Can I trim the audio of a video?
Yes. Choose the MP4, MOV, or WebM, set the part you want, and save it as MP3, M4A, or WAV. The picture is not kept.
Can I add a fade in or fade out?
No. The trimmer makes a clean cut so it can copy MP3, WAV, and M4A without re-encoding. Start and end on a quiet moment, such as a breath or the gap between phrases, and the cut will not click.
Can I cut out a part in the middle?
The trimmer keeps one continuous part. To remove pauses inside a recording, use the free silence remover; to join two kept parts, trim each and merge them.
