Everything You Need to Create Retro Game Assets

A complete AI-powered pipeline for characters, backgrounds, props, and UI... from concept to export-ready spritesheets, built for game developers and pixel artists.

AI-Powered Generation

Use Google Gemini (more providers coming soon) to generate characters, backgrounds, props, and UI elements. Switch providers per project from Settings.

Character Designer

Design characters with AI assistance, then process them through a pixel art pipeline with reference image support for consistent style transfer.

Pose Editor

Manipulate 18-keypoint OpenPose skeletons with FK constraints and a preset library. Export poses for AI-conditioned character generation.

Image Editor

Palette management and color merging, pixel-snap to a clean grid, and scale/resize with variants. Fine-tune AI output to the exact retro aesthetic you want.

Spritesheet Generator & Editor

Generate animation frames from a character and a pose set, then arrange them on a visual timeline, preview playback, and export production-ready spritesheets for your engine.

Style Guide System

Define per-project color palettes, target resolutions, and art direction. Every AI-generated asset (characters, environments, props, and UI) automatically follows your style guide.

Also included: project export/import as .rasproj backups API keys stay on your machine, encrypted

Why Retro Asset Studio?

Built by game developers, for game developers. No subscriptions, no lock-in, no compromises.

Generate characters, backgrounds, props, and UI elements with Google Gemini (more providers coming soon). Use reference images for style transfer. AI accelerates creation while you keep full artistic control.

Professional Pipeline

From concept to export-ready assets in one application. Characters, backgrounds, props, UI elements, pose editing, pixel refinement, and spritesheet export - a complete production pipeline on your desktop.

Free forever · funded by its users

Keep Retro Asset Studio free. Buy the dev a coffee.

There is no paid tier, no subscription and no ads. The app is built by one developer at GameRoad Studio and every coffee goes straight into the next release: a code-signing certificate so Windows stops warning about the installer, macOS and Linux builds, and more AI providers.

A one-off donation takes a minute and needs no account. If the app saved you an afternoon of pixel pushing, that is the moment.

Support on Ko-fi Download first, decide later

Payments are processed by Ko-fi (PayPal or card). Ko-fi takes no cut from one-off donations.

What your support funds

  • Goal 1 Windows code-signing certificate: removes the SmartScreen warning for everyone.
  • Goal 2 macOS and Linux builds: signing, notarization and testing hardware.
  • Ongoing New features and providers: Hugging Face and OpenAI, tilemaps, better animation tools.
  • Always Hosting and the domain: the website and the download server.

Live progress on the current goal is shown on the Ko-fi page. Supporters who want to be listed can say so in their message.

Alpha software

Alpha - help shape it

Retro Asset Studio is in early alpha. Features may change, some things are rough, and your projects should be backed up with the built-in export. Bug reports and feature ideas from real game projects are what make the next release better.
