FAQs
Does cutting an MP3 reduce quality?
No. Stream copy mode duplicates the audio data directly without re-encoding — the trimmed clip is identical in quality to the original.
Can I use this to make ringtones?
Yes — it's the most common use. Cut your favorite chorus and set it as a ringtone; millisecond-precise boundaries make the start point clean.
Is it limited to MP3?
Not at all. WAV, M4A, FLAC, OGG and other common audio formats all trim fine, and video files can be trimmed whole or audio-only.
Is MP3 cutting free?
Completely free. Local in-browser processing, no sign-up, no usage limits.
How precise is the trimming?
Time input goes down to milliseconds, paired with a visual timeline. Stream copy cuts at frame boundaries, so actual precision is one audio frame (~26ms).
