About WaveTrimmer
Your Audio, Perfectly Trimmed
What is WaveTrimmer?
WaveTrimmer is a free, web-based audio trimming tool that helps you cut and edit your audio files with precision. Trim your audio files directly in your browser with support for MP3, AAC, and WAV formats. All processing happens locally on your device - your files never leave your computer.
Key Features
Precise Audio Trimming
Easily select and trim the exact portion of audio you want to keep with our intuitive waveform interface.
Multiple Format Support
Works with popular audio formats including MP3, AAC, and WAV files.
Fast Processing
Browser-based processing means your audio is trimmed quickly without uploading or downloading from servers.
Private and Secure
All processing happens locally in your browser. Your files are never uploaded to our servers.
Extended Audio Support
Need to trim longer audio files? Upgrade to Pro to process audio files longer than 25 minutes.
Intro/Outro Addition
With Pro, you can also append custom intro and outro audio to your files.
Background Noise Reduction
Clean up steady room tone, HVAC hum, and machinery noise with in-browser neural noise reduction on Pro.
Multi-Segment Editing
Mark several clips on one waveform and export them all in a single pass instead of trimming the file over and over.
How It Works
- Upload your audio file (MP3, AAC, or WAV)
- View the waveform and select the section you want to keep
- Switch to Multi-segment mode when you need more than one clip
- Preview your selection
- Download your trimmed audio file
- All processing happens right in your browser
Working with Segments
The editor has two modes. Trim mode keeps a single region of your audio. Multi-segment mode lets you mark as many separate clips as you need on the same waveform, so a long recording can be split into individual pieces without reloading the file between cuts.
- Add a segment to create a new clip, then drag its start and end markers to fine-tune the boundaries
- Segments are color-coded and numbered in playback order so they stay easy to tell apart
- Clear all removes every segment at once, and asks you to confirm first so you never lose your work by accident
- Clearing segments leaves the rest of your session alone. Your loaded audio, zoom level, and output format stay exactly as they were
- Exporting one segment gives you a single audio file; exporting two or more packages them together in a ZIP
Privacy & Security
Your privacy is our priority. WaveTrimmer processes all audio files directly in your browser using client-side technology. Your files are never uploaded to our servers, and we never have access to your audio content. All editing happens on your device and stays on your device.
