Everything you need to split audio fast
Two ways to split
Divide into an equal number of parts, or add custom split points exactly where you want each cut.
Preview before you split
See every resulting segment's start, end, and length before committing, so there are no surprises.
Keeps your original format
Drop in MP3, WAV, M4A, OGG, or FLAC — every output part is saved in that same format, not forced into a different one.
Download one, or download all
Grab an individual part or download every part at once as a single ZIP file.
No part limit that matters
Split into up to 20 equal parts, or add as many custom split points as your recording needs.
Private by design
Your audio never leaves your device. PixelTools runs entirely in your browser using ffmpeg.wasm — zero server uploads, zero data stored.
Three steps to split your audio
- 1
Upload your audio file
Drag and drop an audio file onto the page, or click to browse. Supports MP3, WAV, M4A, OGG, and FLAC files up to 2GB.
- 2
Choose how to split it
Split into an equal number of parts, or add custom split points wherever you want a cut — as many as you need.
- 3
Download every part
Each segment is cut instantly in your browser and saved in the same format you uploaded. Download parts individually or all at once as a ZIP. Nothing is uploaded to any server.
Built for anyone who needs to divide audio into pieces
Whether you're breaking a raw recording into episodes, ripping an album side into individual tracks, or splitting a long interview into shareable clips — PixelTools splits it in your browser in seconds.
Splitting a raw recording into episodes
Cut one long recording session into several separate episode files without re-recording or opening a full editor.
Ripping an album side into individual tracks
Turn one continuous album-side recording into separate track files, split exactly where each song begins.
Breaking up a long lecture or interview
Divide a long recording into shareable clips by topic or question, ready to send separately.
Fitting a messaging app's upload limit
Split a long voice memo into smaller parts that fit under a chat app's file-size or duration cap.
Frequently asked questions
Is PixelTools' audio splitter free?
+
Yes, completely free with no limits. Split as many audio files as you want, into as many parts as you want, as often as you want. No subscription, no trial, no account required.
Are my audio files uploaded to a server?
+
No. PixelTools splits audio entirely in your browser using ffmpeg.wasm. Your files never leave your device — there is no server upload, no cloud processing, and no data stored anywhere.
What's the difference between this and the Audio Trimmer?
+
The Audio Trimmer cuts one start/end range out of a file and gives you a single clip back. The Audio Splitter divides one file into several separate files at once — useful when you want every piece, not just one section.
How many parts can I split an audio file into?
+
In equal-parts mode, up to 20 equally-sized pieces in one pass. In custom mode, you can add as many split points as you need — each point adds one more output file.
What audio formats can I split?
+
PixelTools accepts MP3, WAV, M4A, OGG, and FLAC. Every output part is saved in the same format as the file you uploaded — no forced conversion.
Can I download just one part instead of everything?
+
Yes. Each part has its own download button, or you can grab all of them at once with the "Download all (.zip)" button.
Will splitting reduce my audio's quality?
+
PixelTools re-encodes each part at a high-quality setting for your format (for example, MP3 at a high VBR quality, or lossless PCM for WAV and FLAC), so the difference from the original is minimal to inaudible for typical listening.
How is this different from other online audio splitters?
+
Most sites that advertise an "audio splitter" only let you cut out a single clip — the same as a trim tool. PixelTools actually divides your file into multiple separate output files in one pass, entirely in your browser with no upload and no usage limits.
