Your file stays on this device
The page decodes, trims, previews, and exports in the browser. It does not send the selected audio to an upload server.
MP3 and WAV
Export for sharing or editing
Download MP3 when you need a compact clip, or WAV when you want an uncompressed file for a DAW or audio editor.
Practice
Make useful musical clips
Cut a riff, backing-track section, vocal idea, podcast quote, or lesson excerpt without opening a heavy desktop editor.
How it works
A simple audio cutter workflow
This tool is built for the common job: take a longer audio file, keep the part that matters, and save it in a format you can use right away.
Step 1
Upload an audio file
Start with MP3, WAV, M4A, AAC, OGG, FLAC, or WEBM. The file is read locally by your browser so you can trim it without sending the audio away.
Step 2
Choose the section
Use the waveform selection window and exact time fields to set the start and end point. Keep the whole file or cut out only the part you need.
Step 3
Preview and add fades
Play the selected part before exporting. Add a quick fade in or fade out if the cut begins or ends too suddenly.
Step 4
Download MP3 or WAV
Choose MP3 for a compact everyday clip, or WAV when you want an uncompressed file for editing, sampling, or archiving.
Use cases
What to cut with an audio cutter
Audio cutting is most useful when you already know the moment you need: a phrase to practice, a section to share, or a clean excerpt before another music tool.
Cut practice loops
Trim a difficult riff, solo, or backing-track section so you can repeat the useful part instead of scrubbing through the full recording.
Prepare clips for Audio to MIDI
Short, focused clips usually convert to MIDI more cleanly than long files with silence, noise, or unrelated sections.
Save a quote or lesson moment
Cut spoken audio, interviews, lessons, or voice notes into smaller files that are easier to review or share.
Make a short MP3 clip
Trim a memorable section and export a compact MP3. If your phone needs a specific ringtone format, convert the downloaded file afterward.
Cleaner edits
Make clips that do not start or end abruptly
A good cut is not only about start and end time. Short fades and a focused source file make the result easier to hear, share, and reuse.
Cut from the cleanest source
If the original has noise, distortion, or a very quiet intro, the new clip will keep those problems. Start from the best version you have.
Use tiny fades for smoother edges
A fade of 0.1 to 0.5 seconds is often enough to avoid clicks or harsh starts without making the edit feel slow.
Export WAV before deeper editing
MP3 is convenient, but it is compressed. If you plan to edit the clip again in a DAW, export WAV first and make the final MP3 later.
Audio cutter guide
Audio cutter, MP3 cutter, and audio trimmer: what this page does
People use different words for the same job. Some search for an audio cutter, some search for an MP3 cutter, and others just want to trim audio online. This page keeps those jobs in one tool instead of splitting them into duplicate pages.
When to use an audio cutter
Use an audio cutter when the file format is not the main issue. You may be cutting a WAV rehearsal recording, a phone voice memo, a WEBM export, or an MP3 practice track. The goal is to keep the useful section and remove the rest.
When it works as an MP3 cutter
If you upload an MP3 and download MP3, the workflow is exactly what most people mean by MP3 cutter. The page also supports WAV export because musicians often need a cleaner file for editing.
Why browser-based cutting matters
For many quick edits, installing a full audio editor is unnecessary. A browser cutter is faster for short clips, practice loops, lesson excerpts, and quick sharing, as long as the file is within the browser limits.

FAQ
Audio cutter questions
Does this audio cutter upload my file?
No. The file is decoded, trimmed, previewed, and exported in your browser. The selected audio is not uploaded to a server.
Can I use it as an MP3 cutter?
Yes. Upload an MP3, choose the part you want, preview the cut, then download the result as MP3. You can also download WAV if you need an uncompressed edit.
Which audio formats are supported?
The uploader accepts MP3, WAV, FLAC, OGG, M4A, AAC, and WEBM. Actual decoding depends on your browser, so MP3 and WAV are the safest choices.
Does it work on mobile?
Yes, but large files can be slow on phones. For mobile editing, use shorter clips and close other heavy tabs if the browser runs out of memory.
Will the audio quality change?
WAV export keeps an uncompressed cut. MP3 export creates a new compressed file, which is smaller but not identical to the original audio.
Why is there a file length limit?
The tool edits audio in your browser memory. A limit keeps the page reliable instead of pretending every long recording can be processed on every device.
