Guide — How to Crop Your MP3

Step 1 — Upload: Drag and drop any MP3 (or WAV, OGG, FLAC) file onto the upload zone, or click to browse. Files up to 50 MB are supported.

Step 2 — Select Region: Once loaded, you’ll see the audio waveform. Click and drag directly on the waveform to highlight the portion you want to keep. Fine-tune the selection boundaries using the Start / End sliders beneath the waveform. The selection info updates in real time.

Step 3 — Preview: Press the Play button () to hear your selection, or use the full-file play button to hear the entire track. Press Space to toggle play/stop at any time.

Step 4 — Crop & Download: Click Crop & Download. The tool extracts your selected audio region and encodes it as a high-quality 192 kbps MP3 using the LAME encoder — all inside your browser. The file downloads automatically with “_cropped” appended to the original name.

Tips: Use the Reset button to clear everything and start over. The result panel shows the exact duration, start/end timestamps, estimated output size, and what percentage of the original file you’re keeping. All processing is 100% client-side — your files never leave your device.
