About the Audio Slicer
MP3 Audio Slicer cuts a single MP3 down to a precise time range. Upload the file, type a start and end time in seconds, hit slice, and preview the result before downloading. No re-encoding artifacts, no compression — just a clean clip of the section you wanted.
Everything happens inside your browser. Your audio is never uploaded, never queued on a server, and never logged. Close the tab and it's gone — safe for unreleased music, voice memos, client work, podcast outtakes, or anything else you'd rather not hand to a third party.
What you can control
- MP3 input: Drag & drop or click to upload a single MP3 file from your device.
- Precise time range: Enter start and end times in seconds with 0.1s precision — set exactly the moment to cut in and out.
- Live audio player: Scrub through the full source file to find the timestamps you want before slicing.
- Preview before download: The sliced segment plays in its own player so you can confirm it sounds right before saving.
- One-click download: Save the trimmed clip locally as soon as it sounds the way you want.
Common uses
- Pulling a ringtone or notification sound out of a longer track.
- Trimming a podcast clip down to a quotable highlight for social media.
- Cutting a song down to a specific verse, hook, or chorus for sharing.
- Isolating a single voice memo or interview moment from a long recording.
- Grabbing a short SFX or sting from a sound effect library.
- Removing silence or unwanted intros/outros from MP3 files.
Tips for the best results
- Scrub the source player to find the exact moment you want, then type that timestamp into Start or End for sample-accurate cuts.
- Use the 0.1s step on the inputs (or type in tighter values like 12.45) when you need precise edits — useful for music slicing.
- For ringtones, aim for 20–30 seconds. iOS caps custom ringtones at 30s, so stay under that limit.
- If the slice cuts off mid-word or mid-beat, nudge the end time forward by 0.2–0.5s for a cleaner trail.
- Need to slice a non-MP3 file? Convert it to MP3 first, or use Audio Merger to re-export it as a clean source.
No accounts, no upload queue, no length limits — drop a file, pick a range, and download the slice. Quick edits with no quality loss.
Common questions
How do I cut an MP3 file online for free?
Load the MP3, set the start and end points around the part you want, preview the slice until it is exactly right, and download the segment. The whole job takes under a minute.
Can I make a ringtone from a song?
Yes. Cut the best 20 to 30 seconds, preview it to check the start lands right, and download. Transfer it to your phone and set it as a ringtone from your phone's sound settings.
Can I preview the cut before downloading?
Yes, and you should: the preview plays exactly what will be exported, so you can nudge the boundaries until the slice starts and ends cleanly.
Do my audio files get uploaded?
No. Slicing happens entirely in your browser. Voice memos, interviews, and anything personal never leave your device.
Is there a limit on file size or number of cuts?
No. Your own device does the work, so long recordings slice as easily as short ones, and you can cut as many segments as you need.
