About RustImage
What RustImage Is
RustImage (image.rustwindy.com) is a free online tool for splitting sprite sheets and other image processing, right in your browser. It is made for game developers, UI designers, front-end developers, and illustrators and asset creators.
Features
🆓 Free, no sign-up
No account is needed, and every feature is free to use.
🌐 Nothing to install
It runs in your browser; no software to install.
⚡ Automatic detection
Upload an image and every object is found and cut out automatically.
🔒 Privacy
Uploaded images are deleted automatically, together with their file name and upload IP, about 24 hours after upload. Cut-out images are generated in your browser and never pass through our server. See the Privacy Policy.
How It Works
- Smoothing — reduces noise in the image.
- Edge detection — Canny edge detection finds the edges that outline each object.
- Close gaps and expand — joins broken edges into closed outlines.
- Contour extraction — the area of each closed outline becomes a cut-out region.
