About
About Audio Trimmer
Trimming an audio file is non-destructive in a way that often surprises people, cropping a track's duration doesn't re-encode or degrade the underlying sound fidelity, it simply removes the unwanted portion of the original waveform. This trimmer gives you a visual waveform timeline to drag start and end markers against, which is a far more precise way to find an exact cut point than guessing timestamps blind.
Audio editing used to mean downloading dedicated desktop software just to cut a few seconds off a song, a disproportionate amount of friction for what's often a thirty-second job, trimming a clip for a ringtone or isolating a quote from a longer recording.
A visual waveform makes finding the exact right cut point dramatically easier than scrubbing through audio blind, you can actually see where a word ends or a musical phrase resolves, which matters a lot when precision on the cut point is the whole point of the task.
Upload your audio file (MP3, WAV, AAC, or OGG), drag the waveform's start and end markers to select your clip, and trim. The tool processes instantly and provides your edited file for download.
Personal recordings and music files are yours to edit privately. Processing runs entirely in your browser, with nothing uploaded to a server.
FAQ
Frequently asked questions
What format is the trimmed audio saved in?
The tool always exports a 16-bit WAV file with the same sample rate and channel count as your original, even if you upload an MP3. WAV holds uncompressed audio, so the file runs larger than the MP3. Convert the result to MP3 or M4A afterward if you need a smaller file.
How big will the trimmed file be?
WAV audio at 44.1 kHz stereo uses about 10 MB per minute. A 30 second ringtone clip comes to roughly 5 MB, and a 3 minute song is about 32 MB. Because MP3 files are compressed, the trimmed WAV is usually several times bigger than the file you uploaded.
How do I make a ringtone from a song?
Drag the start and end markers around the 20 to 30 seconds you want, add a short fade in and out, and download. iPhone ringtones must be M4R files under 40 seconds, so convert the WAV afterward. Many Android phones accept WAV, while others need MP3.
Does trimming reduce sound quality?
Cutting does not damage the audio. The tool decodes the file, copies the selected section, and saves it as 16-bit WAV. A compressed source such as MP3 keeps whatever the MP3 held. Changing the gain or adding fades does alter the samples, so leave them off for an untouched cut.
What do the fade and gain controls do?
Fade in and fade out each run from 0 to 3 seconds and default to 0.2 seconds, which removes the click you hear when a cut lands mid-sound. Gain raises or lowers volume from minus 10 to plus 10 dB. Boosting too far can cause clipping, so preview first.
Which audio files can I upload, and is there a size limit?
Upload any audio file your browser can decode, such as MP3, WAV, M4A, AAC, or OGG, and MP4 files with sound. There is no fixed size cap, but the whole file is decoded in memory, so very long recordings can be slow on a phone. Trim long files in parts if the page struggles.
