How to Trim Audio Clips for Instagram Reels and YouTube Shorts — Free Browser Tool
Why Audio Length Matters for Short-Form Video
Instagram Reels cap at 90 seconds and YouTube Shorts at 60 seconds. If your source audio is longer, you need to trim it before attaching it to a video. Getting the exact segment right saves time in your video editor because you arrive with the audio already shaped.
The Fastest Way to Get a 15, 30, or 60-Second Clip
Open Audio Trimmer, upload your audio, and type the exact second values into the start and end fields. Preview to confirm, then export. The duration display shows exactly how long the current selection is, so you can dial it in without guessing.
Add a Fade So the Clip Doesn't Cut Abruptly
Social clips that stop mid-beat or mid-word feel jarring. After trimming, run the result through Fade In / Out with a 0.5-second fade out. This makes the audio feel intentional rather than chopped.
Compress After Trimming for Faster Uploads
Even a 30-second WAV file can be a few megabytes. If you plan to attach it directly to a social post, compress it first with Audio Compressor using the Sharing preset. The output is much smaller and loads faster on mobile networks.
