Trim audio files online instantly using an interactive waveform, precision marks, and accurate time sliders — no upload, no watermark, and 100% free.
BranchAudio’s free online audio cutter is designed to help you trim audio files quickly, accurately, and securely without installing any software. Whether you are editing music tracks, podcasts, voice recordings, or sound effects, this tool gives you full control over your audio with an intuitive waveform-based interface. All processing happens locally in your browser, ensuring complete privacy and instant results.
Unlike traditional audio editing software that requires downloads, system resources, and learning curves, this online audio cutter works directly on modern web browsers across desktop and mobile devices. Simply upload your audio file, visualize it on the waveform, and select the exact portion you want to keep. Once trimmed, you can download your edited file instantly with no watermark and no sign-up required.
The BranchAudio cutter supports commonly used audio formats including MP3, WAV, M4A, and OGG. This makes it ideal for trimming music files, spoken audio, audiobooks, podcasts, interview recordings, ringtones, and sound effects. Whether you are a content creator, student, musician, or casual user, the tool adapts to your workflow without compatibility issues.
Files up to 20 MB can be trimmed smoothly, allowing you to edit short clips and longer recordings efficiently. The optimized waveform rendering ensures responsive performance even on lower-powered devices.
Precision is essential when cutting audio, and this tool is built with that goal in mind. The interactive waveform lets you visually understand your audio content at a glance. You can zoom in to inspect fine details or zoom out to navigate larger sections quickly.
Instead of unreliable drag selection, especially on touch devices, the audio cutter uses accurate start and end sliders combined with a powerful mark system. Marks allow you to save important timestamps while listening, making it easy to return to exact positions later. This is especially useful for trimming podcasts, interviews, and voiceovers where timing matters.
Privacy is a core principle of BranchAudio. Your audio files are never uploaded to a server or stored anywhere online. All trimming and processing takes place locally within your browser using modern web technologies. This ensures your files remain fully private and eliminates the risk of data leaks or unauthorized access.
Because no server-side processing is involved, trimming is instant and does not depend on internet speed after the page loads. This also means there are no hidden limits, accounts, or tracking tied to your files.
Many online audio editors add watermarks, restrict downloads, or require paid subscriptions. BranchAudio’s audio cutter is completely free to use and produces clean, high-quality trimmed audio files with no watermarks. You can use the output for personal projects, professional content, social media, presentations, or client work without restrictions.
The streamlined interface focuses only on what you need: upload, preview, trim, and download. There are no unnecessary distractions or complicated editing tools, making it ideal for quick audio edits and everyday use.
This online audio cutter is suitable for a wide range of use cases. Content creators can trim intros, outros, and highlights for videos or podcasts. Students can extract relevant parts from lectures or recordings. Musicians can quickly cut samples, and professionals can prepare clean audio clips for presentations or applications.
Since the tool works entirely in the browser, it is compatible with Windows, macOS, Linux, Android, and iOS devices. No installations, no updates, and no learning curve — just simple and effective audio trimming whenever you need it.
