An independent AI Halloween photo tool.

An independent tool for Halloween portraits

You upload one photo of yourself or your pet, or two photos for a couple look, pick a look preset and get one 3:4 PNG portrait of you in costume. The AI builds the costume, the lighting and the background from the look you chose.

The result is an AI interpretation, not a promise of an exact look. Upload a photo of yourself (18+) or of your own pet. Couple looks also take one photo of a second adult who appears in the portrait with you and has agreed to it. You must be one of the two people. Public figures, celebrities, minors and anyone who has not agreed are never allowed, including parody and fan edits.

Who we are

HalloweenAI operates this service from China.

What we are not

HalloweenAI.fun is an independent site. We are not affiliated with or endorsed by any film, game, studio, costume brand, Google or the AI providers we use.

It is also not a human service: your image is produced automatically by an AI model.

How the service runs

You sign in with a Google account. Images are generated with Google’s Nano Banana 2 image model (model id gemini-3.1-flash-image-preview), reached through the AI provider Evolink. Payments are one-time credit packs handled by our payment processors, Dodo Payments and Waffo Pancake. One credit makes one image.

How we keep it fair

Credits never expire and are only spent on images that succeed. Failed or blocked generations return their credit automatically. The photo you upload is deleted as soon as your image is ready or the job fails, and the finished PNG is kept for 14 days so you can download it. Images are AI-generated; label them as AI when you share.
