What This Tool Does
Trims audio files to a precise start and end time entirely in your browser, letting you extract clips from longer recordings without installing software or uploading anything.
Who This Is For
- Podcasters extracting short clips for social media previews
- Anyone cutting a voice message or sound bite from a longer recording
- Music enthusiasts isolating a chorus or intro for a ringtone
- Video producers trimming audio tracks to match clip length
Example: Input: A 45-minute interview MP3, need minutes 12:30–18:45 → Output: A 6-minute, 15-second MP3 clip extracted precisely at those timestamps
💡 After trimming, convert the audio to MP3 if it's in a less-compatible format using Any Audio to MP3. For transcribing the trimmed section to text, Audio to Transcript works directly with the trimmed output. To record new audio instead of trimming existing files, Voice Recorder captures microphone input in your browser.
