How local processing works

Each source is decoded, scaled or cropped into its assigned cell, and composited onto one locally encoded canvas.

How to use it

  1. Prepare Make an image collage: Work from a copy and confirm source order, columns, cell width and height, contain/cover mode, focal subjects, gap used as padding, fixed white background, canvas size, and memory. Keep the source unchanged.
  2. Apply Make an image collage: Process locally in the browser. Each source is decoded, scaled or cropped into its assigned cell, and composited onto one locally encoded canvas.
  3. Download and verify: Save under a new name. Inspect every cell for swapped order, cropped faces, stretching, seams, and background color; confirm final pixel dimensions before sharing.

Important limitations

All sources become one flattened raster; individual layers, original resolution, animation, metadata, and some edge content are not preserved.
