How to trim audio online

Keep the part you need. Set start and end times, preview on loop, and download a shorter audio file for free—no signup or added watermark.

  1. 1

    Upload the audio

    Open a song, recording, voice note, or compatible video file.

  2. 2

    Set start and end

    Drag the waveform handles or enter Start (seconds) and End (seconds). The range between them is kept; audio outside it is omitted from the download.

  3. 3

    Preview and add fades

    Enable Loop preview and press Play project to hear the selected range repeatedly. Add Fade in or Fade out if a boundary sounds abrupt, then preview again.

  4. 4

    Trim and download

    Choose an output format and export only the selected section.

When to trim an audio file

Clean up a recording’s beginning and ending

Move Start past setup chatter and End before trailing room noise. Listen to the first and last words so the cut does not remove a consonant or breath. This is manual trimming, not automatic silence detection.

Share a lesson or interview excerpt

Enter the beginning and ending of one useful explanation. Preview the full range to keep its context intact, then export MP3 for convenient sharing. Multiple separate excerpts need Audio Editor.

Prepare an audio cue for a presentation

Retain a short musical phrase or sound effect and test its entry and exit. Add a fade only if appropriate for the cue; fading a sharp hit can remove its impact. Download an audio file to place in your presentation.

Choose a ringtone passage

Find one recognizable section of a song or recording and check it on repeat. For M4R output and phone installation instructions, continue to Ringtone Maker; an ordinary audio download is not an installed ringtone.

Which tool fits your cut?

ToolWhat it keeps or changesChoose it for
Audio TrimmerOne continuous start-to-end rangeShortening a file or creating one excerpt
MP3 CutterAn MP3-specific cutting workflowA dedicated MP3 task, including supported lossless cuts
Audio EditorSeveral retained clips on a timelineDuplicating, arranging, or combining passages

Example: keep the passage from 10 to 25 seconds

Use a recording at least 25 seconds long. This example keeps 15 seconds; the start and end values refer to the original source.

  1. 1

    Enter the range

    Set Start (seconds) to 10 and End (seconds) to 25. Keep speed at 100% for a 15-second result. Values are constrained to the source duration and a valid range.

  2. 2

    Check the boundaries

    Enable Loop preview and press Play project. Listen through the wrap back to the start. Adjust the range or optional fades until the excerpt starts and ends where you need it.

  3. 3

    Choose and download

    Choose your output format and press Trim Audio. WAV avoids lossy output compression; MP3 is convenient for sharing. Compressed formats can add small timing differences such as encoder padding.

Formats, privacy, and trimming limits

One file, one continuous range

This page does not remove multiple internal sections or create multiple downloads at once. The smallest selection is 0.1 seconds, or the whole source if shorter. Rendered output is limited to 30 minutes.

Decoded and rendered, not stream-copied

The editor renders the chosen range and applies any selected effects. MP3 and other lossy exports are re-encoded. WAV output is PCM, but changing settings does not guarantee bit-identical samples or preserve source metadata.

Supported formats depend on decoding

Common MP3, WAV, M4A, AAC, FLAC and OGG inputs, plus compatible video audio, depend on your browser’s codec support. Output choices include MP3, WAV, M4A, FLAC, OGG and AAC. Video imports produce audio only.

Free local-file processing

No account, payment, or audio watermark is required. Local audio is processed in the browser; remote imports and encoder downloads use network requests. Large files may exceed device memory even if the selected range is short. Keep originals and download before leaving.

Before you trim again

I need to delete something in the middle

This page keeps one range. Use Audio Editor to retain and arrange the passages before and after the unwanted section instead of exporting only the middle.

The output duration is different

Check End minus Start and keep speed at 100% if you want that duration. MP3 and other compressed outputs may contain encoder padding; WAV is useful when checking the rendered timing.

The cut sounds abrupt

Move the edge slightly away from a word or transient and try a fade. Loop preview helps reveal abrupt boundaries, but does not automatically make music a seamless loop.

Frequently Asked Questions

What does trimming audio mean?

Trimming keeps a selected start-to-end range and removes everything outside it from the exported copy.

Yes. Use the start and end fields for tenths-of-a-second control in addition to waveform dragging.

Yes. Preview the selected range before export and adjust the boundaries as needed.

Yes. Enable fades to soften the first or last moment of the trimmed file.

Common audio formats and compatible audio tracks from video files are supported. The available export formats are shown in the editor.

Use the trimmer for one continuous range. Use Audio Editor to duplicate, trim and arrange several passages or combine different recordings.
