Turn sketches & photos into game-ready cartoon art (web tool)

I’ve been testing a small web tool called AI Cartoon Generator and thought it might be useful for folks here who need quick concept art, avatars, or social assets.

What it is
A browser-based generator that turns text prompts or photos into stylized cartoon images. You can pick styles (2D/3D, chibi, 90s cartoon vibe, watercolor, etc.), control strength when doing image-to-image, and export clean PNG/WebP. It runs in the browser with server-side generation; no complicated setup.

Why it’s handy for game projects
Rapid prototyping beats blank-canvas paralysis. I’ve used it to rough out NPC looks, try colorways for a mascot, and spin quick banner art for store pages or devlogs. It’s also useful for social: character stickers, cover thumbnails, and event posts.

How I use it (simple loop)

Start with text-to-image to get 8–12 variations of a character.

Pick one, then switch to image-to-image and iterate with small prompt edits (hair, outfit, palette).

Export as PNG (transparent background if you’re making stickers or UI elements).

Prompt recipes that worked well for me

Chibi hero lineup: “chibi fantasy hero lineup, front view character sheet, clean line art, flat colors, high contrast, simple background”

90s Saturday-morning style: “1990s cartoon style, bold outlines, limited color palette, expressive pose, clean background”

Mobile key art: “3D-ish cartoon render, soft rim light, studio backdrop, depth of field, glossy materials, hero shot”
Tip: Keep style words early in the prompt; put content nouns (race/class/gear) next; finish with rendering cues (lighting/materials).

Photo-to-cartoon for avatars
If you want player avatars or team profile icons, upload a headshot and set “strength” low-to-medium so identity stays recognizable while the style changes. Toggle transparent background for in-game UI.

Export & sizes

PNG/WebP; transparent background option for stickers/UI.

For store capsules or social banners, generate at 1.5–2× target size and downscale—edges look cleaner.

If you’re assembling multiple poses, merge assets in your editor, or use a simple image combiner before import.

Licensing & good practice
Use it for original characters. Avoid prompting specific copyrighted IP/trademarks. If you plan to ship assets, double-check the tool’s Terms of Use for commercial allowances and keep a record of your prompts/iterations for provenance.

Happy to share more prompt presets or a small “character sheet” workflow if anyone’s interested.
