Frequently Asked Questions
What audio formats are supported?
You can upload MP3, WAV, OGG, AAC, FLAC, and most other common audio formats. The output is saved in the same format as the original file.
Will trimming reduce audio quality?
No. We use FFmpeg's stream copy mode (-c copy), which trims the audio without re-encoding it. This means zero quality loss — the audio data is kept exactly as-is.
Is my audio file uploaded to a server?
Never. All trimming happens entirely in your browser using FFmpeg compiled to WebAssembly. Your audio file never leaves your device.
Can I trim to the exact second?
Yes. You can set the start and end time with centisecond precision using the MM:SS.cc format (e.g., 01:23.45). The audio player helps you find the right timestamps by playing back the audio.
