⚠️ Please make a backup of your original .pet file before editing!

This editor can be used to adjust the individual personality values of a Petz 3, 4, or 5 .pet file. The editor will automatically read and display your Petz's existing personality traits, which you can then modify as desired. If you wish to revert any changes, use the reset button at the bottom of the page to restore the original values. Once you’re satisfied with your edits, click "Edit Petz File" to generate your updated .pet file. The editor will append _personalityedit to the filename to help avoid overwriting your original file.

🔎 This tool edits only the expressed personality values of your Petz, not their genetic values. These changes will not pass on to offspring. If you wish to modify inheritable personality traits, please use the Personality Gene Editor instead.

⚠️ After saving the edited file, you must run it through PetzByte (by Reflet @ Yabiko) to recalculate the checksum. Otherwise, the file will not work in-game and will appear corrupt.

For more information about petz personality values, check out the RKC Personality Discussion.
You can verify your changes using Reflet's GoalDescriptorAnalyzer program, downloaded at the RKC link above.
