Frequently asked questions
How do I cut a 30-second clip out of a longer video?
Select your video, type the start time (for example 01:10) and end time (01:40), and press Process to save just that clip.
Can I trim MP3 and WAV audio files too?
Yes. Both video containers (MP4, MOV, WebM) and audio files (MP3, WAV, M4A) are supported.
What timestamp format is accepted?
Enter MM:SS (like 00:15 or 03:45) or HH:MM:SS for longer recordings.
Does trimming overwrite my original file?
Never. Your original media stays untouched and a new trimmed copy is downloaded.
