Audio Conversion FAQs
Q. Is 320kbps MP3 always the best?
It offers high quality, but modern formats like AAC or Opus are more efficient at lower bitrates. Choose based on your device.
Q. WAV vs FLAC for archiving?
Both are lossless, but FLAC is better for archiving as it supports metadata and reduces file size by about 50%.
Q. Will converting MP3 to FLAC improve quality?
No. You cannot restore data already lost in a lossy format. The file will be larger but the audio quality remains the same as the source MP3.
Q. Why is the output file larger than the original?
Converting from a lossy format (MP3) to a lossless format (WAV/FLAC) decompresses the audio, which can increase the file size.
Q. Do you support batch conversion?
Yes, you can add multiple files at once. They will be processed and bundled into a single ZIP file for download.
