FLAC Compressor
FLAC Compressor helps you reduce FLAC file size by re-encoding to a different FLAC compression level without changing audio quality. FLAC is lossless at every compression level, so the decoded audio stays identical; the trade-off is encoding speed versus file size. Upload a FLAC file, choose a compression level from 0 (fastest, larger files) to 12 (slowest, slightly smaller files), and optionally enable a verification pass for archival workflows. The backend processes your upload with FFmpeg’s FLAC encoder and returns a downloadable .flac file plus a size comparison so you can see whether recompression helped. This is useful when you have FLACs encoded with a low compression level, when you want to standardize a large library to a consistent level, or when you need smaller lossless files for storage and transfer without switching to a lossy format. A Sample input button provides a real FLAC example to test the full pipeline. An optional AI Assistant can recommend a sensible compression level based on whether you prioritize speed, smallest size, or long-term archiving, but it runs only when you click and all AI processing is handled securely on the backend.

FLAC Converter
FLAC Converter lets you convert audio files to FLAC for lossless archiving or convert FLAC to other common formats for compatibility and sharing. Upload an audio file, choose an output format (FLAC, WAV, MP3, AAC, or OGG), then download the converted result. When exporting FLAC, you can set the FLAC compression level (0–12) to trade encoding time for smaller files while keeping audio lossless. When exporting MP3/AAC/OGG, you can choose a target bitrate (64–320 kbps) to balance file size and quality for your use case. The backend runs the conversion with FFmpeg and preserves stream metadata when possible, so tags are carried through when supported by the target container. A Sample input button provides a real audio example so you can test the full pipeline instantly. An optional AI Assistant can recommend an output format and safe settings based on your goal (archive, editing workflow, sharing, or compatibility), but it runs only when you click and all AI processing is handled securely on the backend.
