Free Audio Trimmer and Cutter Online: 100% Private

No. WAV, FLAC, OGG, AAC, and M4A files are stream-copied — the audio data is not re-encoded, so the output is identical to the input outside the cut region. MP3 is re-encoded at a high quality setting (V2) so the cut points stay accurate.

Absolutely. Since no data leaves your device, it is the safest way to process private recordings or business meetings.

You set the cut points by dragging the waveform handles or typing exact start and end times, so the clip starts and ends precisely where you want it — well suited to ringtones, voice memos, and podcast clips.

An audio trimmer (or cutter) is a tool used to remove unwanted parts from the beginning or end of an audio file, or to extract a specific segment from a longer recording. It’s the perfect tool for creating custom ringtones, cutting out long silences, or isolating a specific quote from an interview or lecture.

Our trimmer uses your browser’s local processing power to handle audio editing. When you select a range on our visual waveform, the tool identifies the exact start and end timestamps and extracts that segment directly in your browser memory. This means no waiting for uploads and absolute privacy for your files.

Most online trimmers require you to upload your file to their servers, which can be slow and poses a privacy risk for sensitive recordings. Submind’s on-device approach ensures your tracks never leave your computer. It’s faster, more secure, and works instantly even with large files.

Simply open Submind’s audio cutter in your browser, drop in your MP3, WAV, M4A, FLAC, or OGG file, drag the waveform handles to select the section you want to keep, and click Trim. The cut happens on your device with no download, no installation, and no upload to any server.
