How to Trim and Cut Audio Clips Online for Free (Step-by-Step)

Whether you're making a ringtone or pulling a podcast highlight, here's how to cut audio to the exact second — for free.

When You Need to Trim Audio

  • Creating a ringtone from your favourite song
  • Pulling a 30-second highlight from a podcast episode
  • Cutting silence from the start/end of a voice recording
  • Preparing a short sample or sound effect
  • How Accurate Trimming Works

    Naive audio cutters often use "input-side seeking," which jumps to an approximate position before decoding — this can be off by a fraction of a second, which matters when you need a clean cut. Our Audio Trimmer uses an ffprobe-based engine that:

  • Probes the file's exact duration first
  • Clamps your requested start/end times to the real length (no out-of-range errors)
  • Decodes from the precise sample using output-side seeking for sample-accurate cuts
  • Step-by-Step

  • Open the Audio Trimmer & Cutter
  • Upload your audio file
  • Enter a start time and end time (e.g., 0:15 to 0:45)
  • Click trim and download your clip as a high-quality MP3
  • Tips for Clean Cuts

  • Add a tiny buffer (0.1–0.2s) before your intended start to avoid clipping the first syllable or note
  • For ringtones, 15–30 seconds is the sweet spot — long enough to recognise, short enough to loop
  • Trim from the chorus or hook, not the intro, for the most recognisable ringtone
  • Frequently Asked Questions

    What's the maximum file size I can trim?

    Up to 150MB per file — plenty for most songs, podcasts, and recordings.

    What format does the trimmed clip download as?

    MP3, encoded at high quality (q:a 2) — compatible with virtually every device and platform.

    Can I trim multiple sections from one file?

    Run the tool once per section you need — each trim produces a separate downloadable clip.

    Next Steps

    After trimming, you can convert your clip to another format like WAV or M4A, or merge several clips into one track.
