VPR is decrypted locally, then saved as FLAC. If the source audio is lossless, it stays lossless in a compact file good for archiving.

About FLAC
Lossless compressed format
FLAC uses lossless compression, cutting file size roughly in half while keeping the original audio quality. It is widely used by audiophiles and for archiving.
- Lossless, identical to the source
- Much smaller than WAV
- Some older players lack support
VPR to FLAC FAQ
Will converting VPR to FLAC lose quality?
VPR is already a lossy format, so converting to lossless FLAC introduces no additional quality loss — existing compression artifacts remain but nothing new is degraded.
Will the file size change after conversion?
Converting to a lossless format (WAV) usually increases size, while converting to a lossy format (MP3, AAC) usually decreases it, depending on the chosen bitrate and sample rate.
How do I batch convert VPR to FLAC?
Just drop multiple VPR files in; they are converted to FLAC one by one via a queue. You can download them individually or as a single ZIP.
