Frequently Asked Questions

  • Is trimming lossy?

    No, not if the output format matches the input — we stream-copy the bytes. Changing format re-encodes once.

  • What formats are supported?

    MP3, WAV, OGG Vorbis, M4A (AAC), FLAC, OPUS, and anything FFmpeg decodes.

  • Does this upload my audio?

    No. Trimming runs in FFmpeg compiled to WebAssembly. Your file never leaves your device.
