Frequently Asked Questions

Will converting to MP3 reduce quality?
MP3 is lossy, so some detail is removed compared with FLAC or WAV. SeerKits defaults to high bitrate presets so casual listening stays clear.
Are my audio files uploaded?
Audio conversion runs locally in supported browsers. Your tracks stay on your device — SeerKits never requires an account for basic jobs.
Can I convert multiple files at once?
The free web tier supports small batches per day. For folder-scale conversion and metadata preservation, open Seer Audio.
