Troubleshooting ICNS to PAM Conversion

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