Frequently Asked Questions
How do I create a photo collage?
Upload multiple photos, choose a grid layout (2x2, 3x1, 2x3, etc.), set gutter width and background color, then download. The Canvas API calculates each cell's position and draws each photo scaled to fit, preserving aspect ratio.
How do I arrange multiple images in a grid?
Divide the target canvas into cells based on your column and row counts. For each cell, calculate x/y position as `(column * (cellWidth + gutter))` and `(row * (cellHeight + gutter))`, then use ctx.drawImage with the cell dimensions.
How do I add borders between collage images?
Set a gutter (gap) value between cells when calculating positions. Fill the canvas background with your border color before drawing images. The visible canvas behind each photo becomes the border.
How do I set the background color of a collage?
Fill the entire canvas with `ctx.fillRect(0, 0, canvas.width, canvas.height)` using your chosen color before drawing any images. The unfilled areas (gutters and padding) will show this background color as borders.
What size should a collage be for social media?
Instagram square: 1080×1080px. Instagram portrait: 1080×1350px. Twitter/X: 1200×675px. Facebook cover: 820×312px. For best quality, work at 2× (e.g., 2160×2160) and export at full resolution.
