Photo Collage Maker
Create downloadable grid collages from multiple images
Usage
After uploading images, the tool auto-suggests target size and grid columns from the current layout: Horizontal uses the tallest uploaded image height, Vertical uses the widest width, and Grid columns are balanced from the image count. You can still edit target size, columns, and gap. A target size of 0 keeps adaptive natural dimensions; positive target size in Grid keeps uniform square cells. Gap defaults to 0 and the result downloads as PNG.
