Audio Trimmer - Cut & Trim MP3 Online Free

A You can trim MP3, WAV, OGG, AAC, FLAC and most common audio formats directly in your browser.

A Processing happens in your browser, so very large files (over 100MB) may be slow depending on your device.

A No. The tool uses stream copy mode which preserves the original audio quality without re-encoding.

A No, absolutely not. This audio trimmer processes all your files directly within your web browser. Your sensitive audio data is never uploaded to our servers, ensuring complete privacy and security. This in-browser processing also means you don't need a fast internet connection for the trimming process itself, only for downloading your finished file.

A Our online audio trimmer is designed for cutting segments from the beginning or end of your audio. To remove a section from the *middle*, you would typically need to perform two separate trimming operations: first, trim the audio *before* the unwanted section, and then, separately, trim the audio *after* it. You would then have two distinct audio files, as this tool doesn't offer joining capabilities.

A Yes, you can keep the intro and outro by setting precise start and end times. For example, if your file is 3 minutes long and you want to keep the first 30 seconds and last 15 seconds, trim from 0:30 to 2:45. The tool cuts everything outside your chosen range. So plan your timestamps carefully before previewing.

A Yes, hit the play button after setting your start and end points. The preview plays only your selected portion, so you can catch mistakes before saving. This saves time compared to trimming blind and redoing it.

A That permission request is for accessing your local files through the File API. No data leaves your device. The tool reads the audio file directly from your computer's storage to process it in the browser's memory. Once you close the tab, everything is erased. If you're trimming a 50MB podcast file, you'll see this prompt. It's standard browser security, and it's actually protecting your privacy.

A Yes, it works with long recordings. The tool runs entirely in your browser, so your device's RAM is the real limit. A 90-minute podcast at 128kbps takes about 80MB of memory. Trim your episode in one go by setting the start and end timestamps precisely. If your computer struggles with huge files, try closing other browser tabs first. For really massive recordings, consider splitting the original file before trimming.

A No, this trimmer works on manual time selection, not audio detection. You set start and end points yourself using the waveform display. For removing silence, you'd need a separate audio editor that analyzes amplitude levels. But here's a workaround: play the file in the preview, tap along to find your timestamps, then punch them in. Most silence removal takes about 10 seconds of manual adjustment.
