Troubleshooting HEIF to MAC Conversion

  • !Converting HEIF to MAC gives blurry output → increase the quality setting before conversion
  • !Colors look different in MAC than HEIF → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → MAC uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in HEIF turned white in MAC → MAC may not support transparency
