About Free Online Audio Cutter
Cutting audio to precisely the right duration is one of the most common audio editing tasks, and our free online audio cutter makes it effortless. Whether you need to trim a long recording down to a specific segment, remove silence from the beginning or end of a file, extract a chorus from a song, or create a short audio clip for social media, this tool gives you exact control over the start and end points of your output. Simply upload your file, set your cut points with millisecond precision, and download the trimmed result in seconds.
The audio cutter handles all major formats including MP3, WAV, OGG, FLAC, and AAC, and uses FFmpeg on our secure backend for reliable processing. The trimmed output preserves the original audio quality — no re-encoding occurs for formats that support lossless cutting, which means your audio sounds exactly as it did in the original file. Files are permanently deleted from our servers immediately after processing, ensuring your audio content remains completely private throughout the workflow.
Key Features
Everything you need — no software installation required.
Precise Start and End Time Controls
Set exact start and end times for your audio cut using time inputs that accept hours, minutes, seconds, and milliseconds. You are not limited to dragging an imprecise slider — you can type exact timestamps like 00:02:34.500 to cut to half-second precision. This level of control is essential for removing unwanted intros, trimming to exact beat boundaries, or cutting clips for use in synchronized video content.
Multi-Format Support
Cut MP3, WAV, OGG Vorbis, FLAC, and AAC audio files with equal precision and quality. Each format is processed with appropriate settings: lossless formats like WAV and FLAC are cut without re-encoding to preserve bit-perfect quality, while compressed formats like MP3, OGG, and AAC are handled with quality-preserving settings to minimize any generational quality loss during the trim operation.
Instant Browser-Based Preview
After setting your start and end points, preview the cut region directly in the browser before committing to the download. The preview player lets you hear exactly what the trimmed output will sound like, allowing you to fine-tune your cut points until the result is perfect. This save-and-preview workflow eliminates the frustrating cycle of trimming, downloading, listening, and retrimming that plagues desktop audio editors.
No Re-Upload Required for Adjustments
Once your audio file is uploaded, you can adjust the start and end times and generate a new cut as many times as you need without re-uploading the file. The original uploaded file stays ready for cutting until you navigate away from the page, allowing you to quickly try different cut points and compare results without the time cost of repeated uploads for each adjustment you want to make.
Lossless Cutting for Uncompressed Formats
When cutting WAV or FLAC files, the tool uses stream-copy mode to extract the desired segment without re-encoding the audio. This means the output WAV or FLAC file is bit-for-bit identical to the corresponding portion of the source file. There is zero quality degradation from the cut operation itself, making this tool ideal for professional audio workflows where maintaining the integrity of the original recording is critical.
Fast Processing on Any Device
The audio cutting operation is performed by FFmpeg running on our optimized server infrastructure, not in your browser. This means even large audio files are trimmed quickly regardless of whether you are using a powerful desktop or a low-end smartphone. The server handles all the computational work and returns only the trimmed segment, making the tool fast and responsive on every device and connection speed.
How to Use Free Online Audio Cutter
Get your result in seconds — completely free, no registration needed.
Upload your audio file
Click the upload button or drag and drop your audio file onto the upload zone. The cutter accepts MP3, WAV, OGG, FLAC, and AAC files up to 500 MB. There is no conversion required before uploading — the tool automatically identifies the format and prepares it for cutting. If you upload the wrong file, you can remove it and select a different one at any time without restarting the process from scratch.
Set the start and end times
Use the start time and end time input fields to define exactly which portion of the audio you want to keep. Enter times in HH:MM:SS.mmm format for millisecond precision, or use the interactive waveform if available to set cut points visually. Use the preview player to listen to the region you have defined before confirming your selection, and adjust the times as needed until the cut sounds exactly right.
Cut the audio
Click the Cut Audio button to begin the trimming operation. FFmpeg on our backend server extracts the specified segment from your audio file. For lossless formats like WAV and FLAC, the cut uses stream-copy mode for zero-quality-loss extraction. For compressed formats like MP3, OGG, and AAC, high-quality settings are applied to minimize any re-encoding artifacts. Most cuts complete in just a few seconds regardless of the source file size.
Preview and download the trimmed clip
When the cut is complete, an audio player appears so you can listen to the trimmed output and verify it starts and ends exactly where you intended. If the result is not quite right, you can go back and adjust the start and end times without re-uploading. Once satisfied with the cut, click Download to save the trimmed audio file to your device. The output filename indicates it is a cut version of the original.

Fast Server-Side Processing
Audio cutting is performed by FFmpeg on our optimized server infrastructure. Even large audio files are trimmed in seconds regardless of your device performance, internet connection speed, or the length of the source recording.
Pro Tips & Best Practices

Use Preview to Fine-Tune Cut Points Before Downloading
Always preview the trimmed audio before clicking Download. The preview player lets you hear exactly what the output will sound like, which is the fastest way to verify your cut points are correct. Fine adjustments of even a hundred milliseconds can make a significant difference in whether a music clip starts cleanly on the beat, whether an interview segment begins at the right word, or whether the tail end of a recording fades out gracefully. Use preview iteratively until the result is exactly right.
For Music, Align Cuts to Beat or Bar Boundaries
When cutting music clips, the most natural-sounding results come from aligning your start and end points to musical beat or bar boundaries rather than arbitrary time positions. Use the waveform visualization to identify the peak amplitude patterns that correspond to beats, and set your cut points at the beginning of a bar for a clean transition. This is especially important for loops, samples, or clips that will be used as background music where abrupt starts and endings are immediately noticeable to listeners.
Add a Short Fade If You Need Smooth Starts and Endings
If you need audio that fades in at the start or fades out at the end, use the volume booster tool after cutting to apply a fade envelope. A cut that starts mid-sentence or mid-note can sound jarring without a fade-in. Similarly, cutting mid-phrase without a fade-out often creates an abrupt ending that sounds unfinished. The combination of precise cutting followed by fade application gives you polished audio that sounds intentionally edited rather than abruptly truncated from a longer recording.
Extract Multiple Segments by Downloading Each Cut Separately
If you need multiple segments from the same source audio file — for example, extracting several quotes from an interview or several musical phrases from a recording — simply upload the file once and perform multiple cuts in sequence. After downloading each segment, adjust the start and end times for the next cut and generate a new download without re-uploading. This makes extracting multiple clips from a single source file fast and efficient without the overhead of uploading the same large file multiple times.
