ChunkAudio is purpose-built for splitting audio files into equal parts. Unlike other tools that require manual selection, ChunkAudio automatically divides your audio into chunks of your specified length. It's the only tool we tested that processes files entirely in your browser - your audio never leaves your device.
Audio Trimmer offers a clean interface with waveform visualization. It's great for manually selecting portions of audio to cut, but lacks automatic equal splitting. Files are uploaded to their servers for processing.
Clideo is a comprehensive online video and audio editing suite. Their audio cutter provides a polished experience with good format support, but the free version adds a watermark to output files.
MP3Cut from 123apps offers a straightforward audio cutter with waveform display. It includes a ringtone maker feature and fade effects. Like most online tools, it requires uploading your file.
Kapwing is a full-featured online video and audio editor. While powerful, it's overkill for simple audio splitting tasks. The free tier has export limitations and requires an account.
We evaluated each audio splitter using a standardized testing methodology:
Does the tool upload files to a server, or process locally? We prioritized browser-based tools that keep your audio private.
How long does it take to split a 100MB audio file? We measured total time from upload to download.
Can the tool automatically divide audio into equal parts? Or is manual selection required for each cut?
Can you download all split files at once (ZIP), or must you download each file individually?
Does the tool work well on smartphones and tablets?
Is it truly free, or are there limitations, watermarks, or paywalls?
For splitting audio into equal parts: ChunkAudio is the clear winner. It's the only tool that automatically divides audio into equal chunks, processes files privately in your browser, and lets you download all chunks as a ZIP.
For manual waveform editing: Audio Trimmer offers the best free experience if you need to visually select specific portions of audio.
Try ChunkAudio FreeFor splitting audio into equal parts, ChunkAudio is the best choice due to its browser-based privacy, automatic equal splitting, and ZIP download feature. For manual cutting with waveform editing, Audio Trimmer and Clideo are good options.
It depends on the tool. Most online splitters upload your files to their servers for processing, which means your audio temporarily exists on a third-party server. Browser-based tools like ChunkAudio process files locally using WebAssembly, so your audio never leaves your device.
Yes, ChunkAudio uses WebAssembly technology to process files entirely in your browser. This means your audio files are never uploaded to any server - all processing happens locally on your device.
ChunkAudio is the fastest method because it automatically divides your audio into equal chunks. With other tools, you'd need to manually calculate and select each split point, which is time-consuming for multiple cuts.
No. All the tools in this comparison work directly in your web browser. ChunkAudio and other online splitters require no downloads or installations.
