About Audio Trimmer

Free online audio trimmer that lets you cut and crop audio files directly in your browser. Upload MP3, WAV, OGG, FLAC, M4A, AAC, or any audio format, then visually select the portion you want to keep using an interactive waveform display with draggable handles. Preview your trimmed selection before exporting, and the tool preserves your original audio format and quality using lossless cutting (no re-encoding). Need to trim multiple files? Upload a batch, trim each one individually, and download them all together as a ZIP file. Perfect for creating ringtones, cutting podcast intros, trimming voice recordings, or extracting the best part of a song. Works entirely in your browser - no uploads to any server, your audio files stay private. Pair this with our [Text to Speech](/tools/text-to-speech) tool to generate audio clips, or use the [Image to PDF Converter](/tools/image-to-pdf-converter) if you need to bundle documents alongside your trimmed audio.

Frequently Asked Questions

What audio formats does this trimmer support?
This tool supports virtually any audio format your browser can play, including MP3, WAV, OGG, FLAC, M4A, AAC, WebM, and more. The trimmed output keeps the same format as your original file, so there is no quality loss from format conversion.
Does trimming reduce audio quality?
No. This tool uses lossless cutting powered by FFmpeg, which means it copies the audio data directly without re-encoding. Your trimmed file has the exact same bitrate and quality as the original. Think of it like cutting a piece of tape rather than re-recording it.
Can I trim multiple audio files at once?
Yes. Upload as many files as you need, and each one gets its own waveform editor where you set individual start and end points. Use the Trim All button to process every file in one click, then Download All as ZIP to grab them together.
Is there a file size limit?
There is no hard limit since everything runs in your browser. However, very large files (over 500 MB) may be slow to load depending on your device's memory. For most audio files like songs, podcasts, or voice memos, the tool handles them without any issues.
Is my audio uploaded to a server?
No. All processing happens locally in your browser using FFmpeg compiled to WebAssembly. Your audio files never leave your device, making this tool completely private and secure.
How do I set precise start and end times?
You can drag the green (start) and red (end) handles on the waveform, or type exact times in the Start and End input fields using seconds. The waveform highlights the selected region so you can see exactly what you are keeping.
