About
What it does
Collage Studio arranges a set of images into a rectangular collage using a proprietary layout solver algorithm. You supply the images and choose a format; the solver finds an arrangement that fills the collage as completely as possible while optionally giving more space and a central positioning to the images you mark as featured.
Everything runs entirely in your browser. The layout algorithm is compiled to WebAssembly and executes locally using your device's CPU cores. Your images never leave your machine — no uploads, no accounts.
How it works
When you create a collage, the app explores a large number of possible arrangements and keeps the one that fills your chosen format most completely while respecting any images you've marked as featured. The search runs in parallel across your device's CPU cores, so even large image sets finish in seconds.
Every run produces a different arrangement, so you can keep creating until you get one you love. The algorithm is tuned automatically for your image count and format — just hit Create and let it work.
Tips
- 1
Use 15 or more images for best results — more images give the algorithm more flexibility to fill the collage.
- 2
Tap any image and choose ×2 or ×3 to give it more space in the collage. Up to 3 images can be featured at once.
- 3
If the result has gaps, try a different format or add more images. Each run finds a different layout, so generating again often closes remaining gaps.
- 4
Save results you like before generating again — each run is non-deterministic and a good layout won't repeat.
