What It Does

Upload a photo of your pet (or any image), and AI generates a ready-to-install animated pixel pet for OpenAI Codex Desktop. The output is a ZIP containing a spritesheet and metadata file -- drop it into your Codex pets folder and your new companion comes to life.

Try it free: codexpetgenerator.com -- no credit card required.

Features

• Upload any photo -- JPG, PNG, WebP, up to 10MB
• AI pixel art generation -- powered by Qwen-Image or OpenAI
• 9 animation states -- idle, walk, run, jump, sleep, die, action, special, interact
• Full spritesheet + JSON -- Codex-compatible format, ready to install
• Animation preview -- see your pet move before downloading
• One-click install commands -- for macOS and Windows
• Free to try -- Starter plan included, Pro for HD and more generations
