What audio file formats are supported?

The converter supports MP3, WAV, FLAC, OGG, and AAC files up to 500 MB. Export your lo-fi track as MP3 (192 kbps) or lossless WAV.

Does this lo-fi converter work on mobile?

Yes. The tool is fully responsive and works on iOS and Android browsers using the Web Audio API. No app download is required.

Is my audio uploaded to a server?

No. All processing happens locally in your browser. Your audio file never leaves your device, ensuring complete privacy.

Will converting to lo-fi reduce audio quality?

The lo-fi effect intentionally reduces high frequencies and adds vintage artifacts for aesthetic reasons. For maximum output quality, use the WAV (lossless) export option.
