StudioWavePro’s Audio Trimmer lets you crop an audio file down to just the part you want — perfect for cutting a song into a ringtone, isolating a podcast quote, removing dead air from a voice memo, or shortening a long recording before you share it. Drop in any MP3, WAV, OGG, M4A, or FLAC file, drag the highlighted region on the waveform to mark the section you want to keep, and download the trimmed result as WAV or MP3. No watermark, no length limit, no signup.

Trimming is sample-accurate — there’s no re-encoding or quality loss when you export to WAV, and the cut points snap precisely to where you place them on the waveform. The block on the waveform is draggable on both edges, so you can zoom in, line up exactly where the music starts, and crop without losing a beat of the intro.

When to use

Cut a song down to a 30-second ringtone or alarm clip.
Isolate a single quote, chorus, or punchline from a longer recording.
Remove silence, false starts, or "uh"s from the beginning of a voice memo.
Trim a podcast intro or outro to a fixed length.
Shorten a long voice note before sharing on WhatsApp, Slack, or email.
Pull a sample out of a song for a remix or beat-making.

How to use

Click "Open Audio Trimmer" below to launch the editor.
Drop in any audio file — MP3, WAV, OGG, M4A and FLAC are all supported.
Drag the highlighted indigo block on the waveform to mark the region you want to keep. The handles on each edge let you fine-tune the start and end points.
Hit Play to preview just the selected region before committing.
Click "Crop to Selection" to keep only what’s inside the block, then download as WAV or MP3.

Tips

Use the side handles on the selection block to fine-tune by a few milliseconds — perfect for catching the exact start of a beat or word.
Hit the Play button while a region is selected to hear only what will remain after trimming.
For ringtones, aim for 25–30 seconds — iPhones cap ringtones at 30 seconds.
Need to keep multiple non-adjacent parts? Use the Audio Splitter tool instead — it cuts a track into multiple files at once.
For lossless trimming, export to WAV. MP3 is fine for most uses but involves a tiny re-encoding step.

Frequently asked questions

Is the Audio Trimmer really free?: Yes — free to use today, no signup, no watermark, no email required.
What audio formats can I trim?: You can drop in MP3, WAV, OGG, M4A, or FLAC files. Trimmed audio exports as WAV (lossless) or MP3 (192 kbps).
Is there a file size or length limit?: There’s no hard limit imposed by the tool, but very large files (over 1 GB or several hours long) may slow down depending on your computer’s memory. For most music files and recordings under 30 minutes you won’t notice any lag.
Will trimming lose audio quality?: If you export to WAV, the cut is bit-perfect — no quality loss at all. MP3 export does a single re-encoding pass at 192 kbps, which is high enough to be transparent for most ears, but if you need absolute fidelity, use WAV.
Can I trim multiple sections at once?: The Audio Trimmer cuts a single contiguous region. If you need to extract several non-adjacent parts of a track, use the Audio Splitter tool — it can output multiple files in one pass.
How do I make a ringtone with this?: Drop your song in, drag the selection to a 25–30 second section (the iPhone limit), and export as MP3. Then convert to .m4r if you’re using iTunes, or use a ringtone-making app for Android.
What’s the best way to share a trimmed clip?: Export to MP3 for smaller file sizes (better for messaging apps and email). Export to WAV when you need maximum quality — useful if the result will be processed further or used in music production.
Can I trim audio from a YouTube video?: You’ll need to download the audio track from the video first using a separate tool (yt-dlp, an online converter, etc.), then drop the resulting file into Audio Trimmer.
