FileFryer Audio Trimmer
Trim, cut, and clip starting and ending points of songs and recordings using an interactive waveform timeline slider.
100% private with zero server uploads.
Precision Audio Cutting Built for Quality & Speed
Everything you need to trim songs, interview soundbites, voice memos, and ringtones directly in your browser.
Dual-Handle Scrubber Timeline
Visual slider handles let you drag and select precisely where your audio clip starts and ends. Highlighted regions clearly distinguish the kept audio from trimmed margins.
Visual Waveform Amplitude Display
Inspect peak decibel waveforms rendered directly from your audio samples. Easily locate quiet breath pauses, drum hits, or silent intro sections for flawless cut points.
Sub-Second Nudge Controls
Fine-tune cuts with ±0.1s and ±1.0s precision nudge buttons. Never miss a musical beat or clip the beginning of a spoken word in podcast recordings.
Loop Selection Preview
Preview the selected cut on repeat before exporting. Verify that ringtone loops and music samples transition seamlessly without audible clipping or abrupt pops.
100% Client-Side Privacy
Unlike web tools that upload confidential voice memos, private interviews, or unreleased music to third-party servers, FileFryer slices your audio entirely inside your browser sandbox.
Lossless WAV & Configurable MP3
Export instantly to crystal-clear uncompressed 16-bit PCM WAV or high-fidelity MP3 (128 kbps to 320 kbps) for ringtones, notifications, and social audio.

Frequently Asked Questions
Common queries regarding formats, processing limits, and offline privacy:
Does FileFryer upload my audio files to any cloud server?
No. FileFryer processes your audio 100% locally on your computer using the HTML5 Web Audio API and client-side WebAssembly/JavaScript encoders. Your audio files, voice recordings, and music tracks never leave your computer.
What audio file formats can I trim?
You can trim all standard web audio formats including MP3, WAV, OGG, M4A, AAC, FLAC, AIFF, and WEBM. The tool outputs pristine 16-bit PCM WAV files or MP3 files at your choice of 128 kbps, 192 kbps, 256 kbps, or 320 kbps.
Can I create custom phone ringtones with this tool?
Yes! Simply upload your song, position the start and end handles around your favorite 30-second chorus, test the loop transition, and export as MP3 or WAV to set as your mobile ringtone or notification sound.
How accurate is the audio cutter?
The trimmer supports sub-second precision down to tenths of a second (0.1s) with dedicated nudge buttons and live playhead alignment hotkeys (I and O). The audio waveform also displays amplitude peaks so you can cut right on the beat.
Is there any audio file size or duration limit?
Because all audio decoding and processing happens directly in your browser without uploading to external servers, there are no artificial file size or duration restrictions. You can trim long podcasts, live recordings, and DJ sets freely.
What is the difference between exporting as WAV vs. MP3?
WAV produces uncompressed, studio-quality 16-bit PCM audio with zero quality loss—perfect for music production and editing. MP3 compresses the file significantly while maintaining clear listening quality with customizable bitrates up to 320 kbps.
