Step 2: Select Your Cut
Drag the blue handles on the waveform to select the section you want to keep. The time displays update in real-time showing start time, end time, and duration of your selection.
Step 3: Preview Your Selection (New!)
Press the spacebar or click the "Preview Selection" button to hear your cut instantly before downloading. Enable loop to continuously hear your selection while adjusting handles.

Cut FLAC, WAV & Lossless Audio Online
Most online audio trimmers only handle MP3 — or claim to support FLAC and WAV but quietly re-encode everything at low bitrates behind the scenes. This tool gives lossless and high-quality formats first-class treatment. Upload FLAC, WAV, AAC, or OGG files and trim them with the same waveform editor, loop preview, and precision handles you get with MP3. The output is encoded at 320kbps MP3 for universal compatibility, and the editing precision is identical regardless of input format.
Because everything runs in your browser, there's no file size limit imposed by a server upload queue. FLAC files — which are often 3-5x larger than their MP3 equivalents — load and process just as smoothly. If you work with lossless audio libraries, vinyl rips, or studio recordings, this is the trimmer that won't force you to convert first.
Frequently Asked Questions
How do I cut an MP3 file online?
Upload your MP3 file, drag the handles on the waveform to select the section you want to keep, press spacebar to preview your selection instantly, adjust until perfect, then click "Cut Audio". Your trimmed MP3 downloads immediately.
Can I hear my selection before cutting?
Yes — this is what makes this trimmer different. Press spacebar or click "Preview Selection" to hear your cut instantly. Enable loop preview to hear it on repeat while you adjust the handles in real-time. Change playback speed from 0.5x for precision to 2x for scanning. The green progress line shows exactly where you are during playback.
What audio formats does this trimmer support?
MP3, FLAC, WAV, AAC, and OGG. All formats get the same waveform editor, loop preview, and fade effects. Output is high-quality 320kbps MP3 for universal compatibility.
Can I trim FLAC and WAV files?
Yes. Upload FLAC or WAV files directly — no conversion needed. The waveform, preview player, and all editing features work identically with lossless formats. Most competing trimmers either reject FLAC or require you to convert it to MP3 first.
Will trimming reduce my audio quality?
No. The audio stream is copied without re-encoding, preserving the original quality exactly.
How do I create audio clips for TikTok or Instagram Reels?
Upload your song, use the waveform to find the 15-30 second section you want, enable loop preview, and adjust the handles while listening until you've nailed the exact beat drop, hook, or moment. Then cut and download. The loop preview eliminates the guess-and-check cycle that makes other trimmers frustrating for short-form content.
Can I make a ringtone with this audio cutter?
Yes. Trim your song to 30-40 seconds, add fade in/out effects, and download. Preview with loop makes it easy to find the perfect section — the chorus, a guitar riff, or any memorable moment. Works for iPhone and Android.
How do I remove unwanted parts from a song?
Drag the handles to select the part you want to KEEP (not remove). Everything before the start handle and after the end handle is cut. Use preview to hear exactly what you're keeping before you commit.
Is this really free? What's the catch?
Completely free with no limitations. No subscriptions, no file limits, no hidden fees, no watermarks. The tool runs in your browser — your files are never uploaded to any server, which also means there's no server cost for us to pass on to you.
Do my files get uploaded to a server?
No. Everything runs locally in your browser using WebAssembly. Your audio files never leave your device. This makes it faster than server-based trimmers (no upload/download wait) and completely private.
What devices and browsers are supported?
Works on Windows, Mac, Linux, iOS (iPhone/iPad), and Android in any modern browser. The interface is touch-friendly — dragging waveform handles works on mobile. No apps or plugins to install.
What's the maximum file size?
Most audio files up to several hundred MB work smoothly. Since processing happens on your device rather than a server, there's no artificial upload limit. Very large files (1GB+) depend on your device's available memory.
