What Collage Studio does
Design custom photo grids, Instagram collages, and masonry layouts with gaps, border controls, and scale/offsets.
How it works
Uses Canvas2D and WebGL2 with OffscreenCanvas for parallel processing. Filters run as GPU shaders where supported, falling back to CPU SIMD via WebAssembly. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
