Audio Splitter

Free Online Audio Splitter

Split and cut audio files online for free — no upload, no sign-up, no watermark. This audio splitter runs entirely in your browser using FFmpeg compiled to WebAssembly, so your files are processed on your own device and never sent to a server. Use it to cut a song, break a long recording, lecture, podcast or audiobook into chapters, or grab a single clip with millisecond precision.

Four ways to split

• Extract a segment — set a start and end time and keep just that part.
• Equal parts — divide the file into N evenly sized pieces.
• Every X seconds — chunk a long recording into fixed-length files.
• At timestamps — paste your own cut points to split at chapters or track marks.

How to Use

1. Upload an audio file, or paste a direct audio URL.
2. Choose a splitting mode and enter your times — accepts HH:MM:SS.mmm, MM:SS or plain seconds.
3. Click Split Audio and wait for processing to finish.
4. Preview each segment in the player, then download them individually or all at once as a ZIP.

Supported File Types

Audio: MP3, WAV, M4A/AAC, FLAC, OGG, Opus, WMA and other common formats. Each segment is saved in the same format as the file you started with.

Quality & Accuracy

Segments are copied out without re-encoding, so there is no quality loss and splitting is fast. Because compressed audio is stored in frames, cut points land on the nearest frame boundary — typically within a few hundredths of a second of the time you asked for.

Privacy and Security

We respect your privacy. This tool is a browser-based application, which means your files are processed directly on your device. No audio is ever uploaded to our servers.
