Combines 2–20 images into horizontal, vertical, or grid (2–4 cols) collages with spacing 0–40px, background color, and rounded corners 0–20px. Scales each image to fit its cell, draws to canvas, and exports as JPEG/PNG/WebP.
Collaging photos for mood boards or comparison grids usually means cloud editors that see your images. This composites locally on canvas with precise layout math, so your photos stay private and you control spacing and background.

collaging is canvas-only in your browser. Images never leave your device.
How are images scaled?
Each image is scaled to fit its cell with `min(cellW/imgW, cellH/imgH)` centered, clipped to rounded rect if radius > 0.
Can I mix orientations? Yes
each cell centers its image regardless of aspect.
What is the max size?
Preview caps at 260px cells; final canvas is cells × spacing, up to ~2000px, to avoid memory issues.
