Who uses this audio trimmer?
Six common workflows where in-browser audio trimming saves a download, an install, or an upload.
AI voiceover clean-up
TTS tools like MindLink Voice Studio, ElevenLabs, Murf, and PlayHT typically produce clips with a half-second of dead air on either side. Trim it in seconds before publishing.
Podcast snippets
Cut a 30-second highlight from a full episode for social media. Drop in the MP3, drag the handles, download.
YouTube voiceovers
Trim the awkward false-start at the beginning of a recorded voiceover, or the "okay that's a wrap" at the end, before adding the file to your video editor.
Voice memos
Got a 5-minute voice memo with the useful part in the middle? Drop it in, isolate the part you actually want, send only that.
Language learning clips
Extract a single phrase from a longer recording for pronunciation practice. Works great with audiobook chapters and podcast interviews.
Ringtones & alert sounds
Cut a 10-second clip from a longer track. The WAV export plays natively on every phone OS.
How to trim an audio file online

- 1
Upload your audio file

- 2
Drag the orange markers to set start and end
Two draggable orange handles let you pick exactly where the trimmed clip should start and end. A live waveform shows you what is inside the selection.
- 3
Preview the selection
Click Play selection to hear only the trimmed range. Click anywhere on the waveform to move the playhead. Tweak the markers until the cut feels right.
- 4
Download as MP3 or WAV
Click Download MP3 (with bitrate selector — 128/192/256/320 kbps) or Download WAV for lossless. The file saves to your device immediately. No watermark, no signup, no daily limit.
What is audio trimming?
Audio trimming is the process of cutting an audio file down to a specific section — keeping only the part you want and discarding the rest. Unlike audio editing (which can involve mixing, equalization, effects, and multi-track work), trimming is the simplest possible operation: pick a start point, pick an end point, save the section in between.
It is the single most common audio task on the web. Whether you are preparing a podcast highlight clip for Twitter, cleaning up a voicemail forward, isolating a quote from a YouTube interview, or polishing an AI-generated voiceover before you publish, you are trimming. Most paid editors are overkill for this — Audacity is a full DAW, Adobe Audition costs ₹1,800+/month, and most online editors lock format options behind a paid plan.
This tool does exactly one thing well: it lets you trim an audio file with a real waveform, real preview playback, and a real download — for free, with no signup. Modern browser APIs (Web Audio, AudioBuffer, MediaRecorder) make this possible client-side, which means your file never leaves your device and we have zero hosting cost for serving the tool.
Your audio never leaves your device
Most online audio editors upload your file to their servers, queue it for processing, and force you through a download flow. This tool runs entirely client-side — no upload, no queue, no waiting.
The Web Audio API decodes your file locally into an AudioBuffer. A pure-JavaScript WAV encoder writes the trimmed section back to a Blob. The Blob URL is handed to a hidden <a download> tag and clicked. Nothing touches the network at any step.
Want to verify? Open browser DevTools → Network tab → trim and download a file. You will see zero requests during the operation. The audio stays on your machine, period.

Frequently asked questions
Everything people ask about online audio trimming, condensed.
Is this audio trimmer really free?+
Yes — fully free, with no signup, no watermark, no time or file-size limit, and no daily quota. The entire tool runs in your browser, so it costs us nothing to serve, and we never store or transmit your audio.
Does my audio get uploaded anywhere?+
No. The trimmer uses the Web Audio API and pure JavaScript to decode, edit, and export your file directly. Open browser DevTools and you will see zero upload requests during trimming or export.
What audio formats are supported?+
Any format your browser can decode: MP3, WAV, M4A (AAC), OGG, FLAC, WebM audio, and Opus. On Chrome, Edge, and Safari this covers virtually every common audio container. Export is available as WAV (lossless) or MP3 (with bitrate options 128–320 kbps).
Is there a file-size limit?+
The only limit is your device memory. The tool has been tested with files up to roughly 30 minutes of stereo MP3 (around 30 MB). Very large podcast files (1 hour+) may slow waveform rendering on low-end mobile devices but still work.
Can I trim AI-generated voice clips from ElevenLabs, Murf, or MindLink Voice Studio?+
Yes — this is one of the most common use cases. Generate the voice clip in your TTS app, download the MP3 or WAV, drop it into this trimmer, cut the silence at the start or end (or any breath you do not want), and export. Most TTS tools produce clips with a half-second of dead air on either side that this tool removes in seconds.
Can I export to MP3?+
Yes. Click "Download MP3" instead of "Download WAV". The MP3 encoder (~2.5 MB of code) downloads on first click and stays cached for subsequent exports. You can pick the bitrate: 128, 192, 256, or 320 kbps. WAV stays available too for users who need lossless output.
Does it work on iPhone and Android?+
Yes. Mobile Safari (iOS 14.5+) and Chrome on Android both support the Web Audio API and MediaRecorder needed for this tool. Touch dragging on the markers works the same way as mouse dragging on desktop.
How is this different from desktop or online audio editors?+
Desktop editors like Audacity are overkill if all you want is to cut one clip. Most online editors upload your file to their servers, wait for processing, and often watermark or restrict downloads behind a signup. This tool has no signup, no watermark, no quota, and operates on your audio in seconds — entirely in your browser.
Can I edit multiple sections or do fades?+
Not yet. Version one supports single-range trim only. Multi-segment cuts, crossfades, and gain control are planned for the next iteration.
Does this tool track me or run ads?+
No ads. The page uses Google Analytics for aggregate visit counts (the same as the rest of the MindLink site) but the audio editor itself sends no telemetry about what you trim, what you export, or how long you spend.
