Are my audio files uploaded to a server?
No. The Audio Trimmer runs 100% locally in your browser using WebAssembly. Your files are never uploaded to any server, ensuring total privacy.
What audio formats do you support?
We support all common audio formats including MP3, WAV, OGG, M4A, AAC, and FLAC, relying on your browser's native decoding capabilities.
Is the audio quality degraded when trimming?
No, we use ffmpeg to accurately extract the audio segment without re-encoding the original data if possible, maintaining the highest quality.
How does 'Snap to Zero-Crossing' work?
Our trimmer analyzes the audio wave and snaps your selection points to moments of silence (zero amplitude) to prevent audible clicks or pops at the cut points.
Can I edit very large audio files?
Yes, our high-performance canvas waveform allows you to smoothly scroll and zoom through hours of audio without slowing down your browser.
Is this tool free to use?
Absolutely. Our Audio Trimmer is entirely free to use with no hidden fees, subscriptions, or watermarks.
Can I zoom in for precise editing?
Yes, use your mouse wheel or the provided zoom slider to magnify the waveform for millisecond-level precision.
Can I listen to just the selected part?
Yes, clicking the Play button while you have a selection active will loop playback strictly within your chosen start and end points.
Do I need to install any software?
No installation is required. The tool operates completely within your modern web browser using standard web technologies.
Can I use this on my mobile device?
Yes, the tool is fully responsive and optimized for mobile browsers, although desktop is recommended for precise control.
What happens if I accidentally refresh the page?
Since all processing is done locally without accounts, refreshing will reset your session and you will need to load your file again.
Why does the export take a few seconds?
Exporting utilizes ffmpeg running inside your browser via WebAssembly to guarantee a valid output file. For larger files, encoding might take a brief moment.
Can I trim multiple parts at once?
Currently, our tool supports trimming a single, continuous segment per export. You can repeat the process for multiple cuts.
Is there a file size limit?
Since everything runs in your browser, the limit depends on your device's available RAM. Files up to a few gigabytes are typically handled well on modern devices.
Can I extract audio from a video file?
Yes, if your browser supports decoding the video format (like MP4), our tool will automatically extract and display its audio track for trimming.
