Audio Clipper: Trim & Cut Audio Files Online Free, No Upload

About the Audio Clipper

Drag the handles on the waveform to select your clip region, or type exact times in the Start and End fields using H:MM:SS format. Preview the selection before you commit, then export it as MP3, WAV, or OGG. FFmpeg, compiled to WebAssembly, handles the actual cut inside your browser tab, so nothing you upload ever reaches a server.

How the trim works

When you drop a file, the browser's Web Audio API decodes it into raw PCM samples and the tool draws a waveform from those samples by scanning the file into 1200 bins and plotting the loudest peak in each one. That waveform is what you see and drag against, not a static image, so it reflects the actual amplitude of your file across its full length. Dragging the blue handles or editing the time fields updates the selected region in real time, and the Preview button plays back exactly that region through the same decoded buffer, before any export happens. Once you hit export, the tool hands your original file and the selected start and end times to FFmpeg, which seeks to the start point and re-encodes only the selected duration into the format you chose.

Setting a precise clip region

Coarse trims are easiest with the waveform: click and drag either handle toward the section you want to keep, watching the shaded region for a quick visual check against the peaks and dips in the audio. For sample-accurate cuts, type exact timestamps into the Start and End boxes instead. Any of SS, M:SS, or H:MM:SS is accepted, and decimals work too, so 1:23.5 lands you at one minute and twenty three and a half seconds. The duration readout between the two fields updates immediately so you can confirm the clip length before exporting, and the preview button lets you listen to the exact selection as many times as you want before committing to an export.

Choosing an output format

WAV keeps the trimmed audio at full PCM quality with no re-encoding loss, which matters if you plan to feed the clip into another editor or DAW afterward. MP3 is the safest default for sharing, uploading, or attaching to email, since virtually every device and platform plays it without question. OGG trades some compatibility for smaller files at comparable quality, a good fit for web projects and podcast pipelines that already standardize on it. All three formats go through the same frame-accurate seek and cut, so the choice comes down to what you are going to do with the file next, not how precisely it gets trimmed.

Common use cases

Podcasters use the clipper to pull a single quote or highlight out of a longer recording for social posts. Musicians trim a full song down to a 30-second preview or extract a specific verse for sampling. People cutting a long voice memo down to the one useful segment skip opening a full audio editor entirely. Because the tool accepts MP3, WAV, AAC, M4A, OGG, FLAC, OPUS, WMA, and AIFF as input, it works as a quick front door for whatever format a recording happens to arrive in, before you decide what to do with the trimmed result.

Working entirely offline

The FFmpeg engine downloads once, around 32 MB, and the browser caches it after that first load, so every clip after the first runs without touching the network again. Your file, the waveform data, and the exported clip all stay on your machine throughout the process. If you are trimming anything sensitive, an interview recording, a private voice memo, unreleased music, that local-only processing means there is no upload step to worry about in the first place.

Tips for a clean trim

Zoom in mentally on the waveform when you are cutting near speech or music, since a handle placed a few pixels off can chop the start of a word or the attack of a note. If you catch that after export, reopen the source file and nudge the start or end field by a tenth of a second rather than redrawing the whole selection by hand. When trimming from a long recording, use the time fields to jump straight to an approximate timestamp first, then fine tune with the waveform handles once you are close, which is faster than dragging across several minutes of audio at once. Preview the selection at least once before exporting, since a quick listen catches boundary issues that a glance at the waveform alone can miss.
