Trim MP3, WAV, OGG Files Instantly

File Studio's audio trimmer supports all major audio formats including MP3, WAV, and OGG. Upload your file and use the visual waveform editor to set precise start and end points. The trimmed audio downloads in the same format as your original file, preserving audio quality. This is perfect for cutting intros, removing silence, extracting specific segments from recordings, or creating ringtones from songs.

Waveform Preview for Precise Cuts

The visual waveform display shows you exactly where sounds, speech, and silence occur in your audio file. Zoom into specific sections for frame-accurate trimming. Playback previews let you verify your cut points before processing. This visual approach is far more accurate than guessing timestamps and produces professional results without professional software.

No Upload — Audio Never Leaves Your Device

Audio files often contain sensitive content — private conversations, unreleased music, confidential recordings. File Studio processes all audio editing locally in your browser using the Web Audio API. Your audio files are never uploaded to any server, ensuring complete privacy for sensitive recordings.
