How to Trim Audio Online

Upload your audio file

Drag and drop your MP3, WAV, OGG, FLAC or AAC file into the upload area, or click to browse your device. Files above 100 MB are refused before decoding starts. The waveform appears once the track has decoded, so you can see the whole file at a glance.
Set start and end times

Use the time inputs or drag the selection handles on the waveform to mark exactly where you want the clip to begin and end. The trimmed duration updates in real time as you adjust.
Preview the trimmed section

Click Preview Trim to listen to your selected segment before committing. Adjust the start and end points if needed until the clip sounds exactly right.
Trim and download

Click Trim Audio to process the selection. The tool exports a high-quality WAV file that downloads directly to your device. No account or email required.

Common Use Cases

Podcast Editing

Remove awkward silences, long intros, or off-topic tangents from podcast recordings before publishing. Trim individual segments and assemble them in your editor of choice.

Ringtone Creation

Cut your favorite song down to a 20-30 second clip for a custom ringtone. Trim the exact chorus or hook you want, then convert the output to MP3 or M4R format.

Music Sampling and Loops

Extract drum breaks, vocal phrases, or instrument loops from existing tracks for use in music production. The lossless WAV output preserves full fidelity for further processing.

Voice Memo Cleanup

Cut dead air and irrelevant sections from voice memos, lecture recordings, or interview audio before sharing or transcribing.

Why use our Audio Trimmer?

Our audio trimmer cuts a section out of an audio file without sending it anywhere. Whether you need to remove silence, drop an intro, or pull one segment out of a long recording, you set the start and the end on the waveform and export just that piece. The audio is decoded and cut in your browser with the Web Audio API, so the file itself stays on your device. Input covers MP3, WAV, OGG, FLAC and AAC up to 100 MB, and the output is always a lossless WAV.

FindUtils Audio Trimmer is a browser-based tool that cuts, splits and shortens audio files without uploading anything to a server. It accepts MP3, WAV, OGG, FLAC and AAC input up to 100 MB, and uses the Web Audio API to decode and cut the audio on your own device. The output is a lossless WAV, so nothing is re-compressed on the way out. No signup, no watermark and no usage limit.

Whether you are editing podcast episodes, creating custom ringtones, extracting samples for music production, or cleaning up voice memos, this tool handles it in seconds. The waveform makes it easy to see exactly where to place your cut points, and the preview lets you listen to the trimmed segment before downloading. If you also need to change the sample rate of your audio, the Audio Resampler can handle that. For converting between formats after trimming, use the Audio Format Converter.

Audio trimming is often the first step in a larger editing workflow. After trimming, you might extract the audio from a video file using the Video to Audio Converter, inspect the technical details with the Audio Metadata Extractor, or trim the video itself with the Video Trimmer. All of these tools run in your browser, and in each of them the file you load stays on your device.

How it compares

Most online audio trimmers require you to upload files to a remote server, wait for processing, and then download the result. Services like mp3cut.net and clideo.com follow this model, which means your audio passes through third-party infrastructure. FindUtils Audio Trimmer is different: the audio is decoded and cut locally with the Web Audio API built into your browser. The tool code uploads nothing and stores nothing, there is no queue, and the only cap is the 100 MB the page will accept. The page itself loads analytics and ad scripts, as most websites do; they are separate from the tool code.

Paid desktop software like Adobe Audition or Audacity offers more advanced editing features such as multitrack mixing, effects chains, and noise reduction, and it can write MP3 or FLAC directly instead of WAV. However, for the common task of cutting a clip to specific timestamps, a browser-based tool is faster and requires zero installation. FindUtils Audio Trimmer fills that gap: quick, precise trims with lossless WAV output, free and without an account.

Tips for Better Audio Trimming

Zoom into the waveform to place your start and end markers with frame-level precision, especially when trimming speech or musical beats.
Always use Preview Trim before exporting to confirm your selection sounds natural without abrupt cuts.
For clean cuts, try to trim at zero-crossing points in the waveform where the signal crosses the center line. This prevents audible clicks or pops.
If you need a specific output format like MP3 or OGG instead of WAV, run the trimmed file through the Audio Format Converter immediately after downloading.
Keep the original file untouched. Since this tool never modifies your source, you can re-trim with different start and end points as many times as needed.

Frequently Asked Questions

Is this audio trimmer free?

Yes. The audio trimmer is free, with no signup, no watermark and no usage limit. It accepts files up to 100 MB and writes a lossless WAV.

Are my files uploaded to a server?

No, not the file. The audio is decoded and cut in your browser, and the tool code sends no part of it to a server. The page itself loads analytics and ad scripts, as most websites do, so a network monitor shows requests from those. They are separate from the tool code.

What audio formats are supported?

Input covers MP3, WAV, OGG, FLAC and AAC, and the output is always a lossless WAV. Decoding uses the browser's own audio decoders, so FLAC and OGG support depends on the browser you are in.

Will trimming reduce audio quality?

No. The trimmer writes lossless WAV, so the cut section keeps the quality it had after decoding and nothing is re-compressed on the way out. What it cannot do is improve a lossy source: an MP3 trimmed to WAV keeps exactly the quality the MP3 had.

Is there a file size limit?

Yes. The trimmer accepts files up to 100 MB and refuses anything larger before decoding starts. Within that cap, a long file takes longer to open, because the whole track is decoded in your browser before the waveform appears.

Can I trim MP3 files without converting them?

No. The trimmer accepts MP3 input, but it decodes the audio with the Web Audio API and writes the result as lossless WAV rather than re-encoding a new MP3. That avoids a second round of compression loss. If you need MP3 output, run the trimmed WAV through the Audio Format Converter.

How do I cut a specific section from the middle of an audio file?

Set the start time to where your desired section begins and the end time to where it ends. Use the waveform display to visually identify the segment, then click Preview Trim to listen before exporting.

Can I use this tool to make ringtones?

Absolutely. Trim your song to 30 seconds or less, download the WAV file, then convert it to your phone's preferred format using our Audio Format Converter. Most phones accept MP3 or M4R ringtones.

Does the audio trimmer work on mobile devices?

Yes. The tool runs entirely in your browser using the Web Audio API, so it works on modern smartphones and tablets. Performance depends on your device's processing power and available memory.

Can I trim multiple audio files at once?

No. The tool processes one file at a time, so the waveform and the preview always match the file you are about to download. Load a file, set the start and end points, trim, download, then reset for the next one.
