Frequently Asked Questions

Yes — completely free, no limits, no watermarks, no account required. Convertlo runs entirely in your browser using FFmpeg.wasm.

No. All trimming happens locally in your browser. Your audio file never leaves your device.

Most common formats work, including MP3, WAV, M4A, OGG, AAC, and FLAC. The trimmed clip is saved in the same format as your original file.

Convertlo first tries a fast, lossless cut. If your start time needs to be sample-accurate, the tool automatically re-encodes the clip for a precise cut.

There's no hard limit, but very large files use more memory and take longer to process since everything runs in your browser. For best results, keep files under 200 MB.

When a fast cut is possible, there is no quality loss at all. If re-encoding is required for precision, quality is kept as close to the original as possible.
