Frequently asked questions
How precise is the trim?
Down to the second — type exact start and end times (for example 12.5 to 48.0). Audio re-encodes at keyframe boundaries the way MP3 works, so the cut lands within a fraction of a second.
MP3 or WAV — which output should I pick?
MP3 (192 kbps) for everyday listening and sharing — small files, great quality. WAV (lossless) when you plan to edit, mix or master the clip further.
Can I trim the audio of a video file too?
Yes — drop in an MP4 or WebM and this tool trims its audio, giving you an MP3 or WAV of just the selected range.
Does my audio leave my device?
Never. Trimming runs entirely on your device using a WebAssembly build of FFmpeg, loaded unmodified from a CDN. Your file is never uploaded to any server.
Is it really free? Any watermark?
Yes — 100% free with no signup and no watermark, and no limit on how many files you trim (files up to 500 MB are supported).
Which formats can I upload?
MP3, WAV, M4A, OGG, FLAC and most common audio formats, plus video files. The trimmed clip downloads as MP3 or WAV — your choice.
