From a recording to a file you can use
- 01
Choose a file
Use a recording you have the rights to edit. The browser needs to decode its audio, so the extension alone does not guarantee it will open.
- 02
Adjust one thing
Choose cuts, a playback rate, a gain or an output format. Check what that tool changes before combining several edits.
- 03
Review the result
Listen near the cuts and at both ends of the export range. Check the selected track, expected duration and peaks after a gain change.
- 04
Export a new file
Download the result and open it in the app where you will use it. Keep the original recording for later revisions.
Which audio tool fits your task?
Each tool changes a different part of your recording. Compare the result and the limits before choosing a file.
Scroll the table horizontally to compare all columns.
| Tool | What changes | Before you save |
|---|---|---|
| Silence Remover | Find quiet gaps by level and duration, keep room around speech, then review and export MP3. | Quiet speech and breaths may be detected as silence. Review each cut. |
| Audio Trimmer | Set the export range, remove mistakes or extra sections, then check the joins and export MP3. | Cuts join directly. Listen across each join. |
| Video to Audio | Choose a decodable audio track from a local video, listen and save it as MP3. | Audio-only output. The video picture is not preserved. |
| Volume Changer | Apply −12 to +12 dB of fixed gain, check the predicted peak, then listen and export MP3. | Gain also raises background noise. Lower it if the peak exceeds full scale. |
| Speed Changer | Choose a rate from 0.75× to 1.5×, listen to the result and export MP3. | Pitch changes along with speed. |
| Format Converter | Choose one audio file and convert it to MP3, WAV, FLAC, M4A, AAC or OGG. | Encoding availability depends on your browser. Conversion cannot restore lost detail. |

A new file, not a saved project
Export creates a new file and keeps the source unchanged. Refreshing or closing the tab ends the editing session. Download your result before leaving; the website does not save a project for your next visit.
Choose by the actual task
These tools do not clean background noise, identify spoken filler words or preserve video pictures. Speed changes also change pitch. Use the tool that fits the result you need.
Before you start
Common questions.
Do I need an account?
No. The six AudioCut tools are free to use and do not require an account.
Are my files uploaded?
No. The current tools process supported media in this browser. The selected file, filename, waveform and result are not sent to AudioCut.
Which files work?
MP3, WAV, M4A, AAC, FLAC, OGG and Opus are supported, along with MP4, MOV and WebM when the browser can decode their audio track.
Can I edit the picture in a video?
No. A video is used as an audio source. AudioCut exports an MP3 and does not edit the picture.
Will the original change?
No. The source file stays unchanged and the tool creates a separate audio result.
Can I use AudioCut on a phone?
Yes, in a modern browser. Codec support and device memory still affect which files work, so test an important edit with a short copy first.
