VPR to M4A FAQ

Will converting VPR to M4A lose quality?

Both VPR and M4A are lossy formats. Re-compression may further reduce quality — choose a higher bitrate to minimize additional loss.

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 M4A?

Just drop multiple VPR files in; they are converted to M4A one by one via a queue. You can download them individually or as a single ZIP.
