Photo collages date back to the Victorian era (1837-1901) when people would cut and paste photographs into elaborate scrapbooks as a popular pastime. The term "collage" comes from the French word "coller" meaning "to glue." The first artistic photo collages were created by Dadaists in the 1920s as a form of political expression. Before digital tools, magazine editors used light tables and adhesives to create layouts. Today, over 2 billion digital collages are created annually worldwide. Research shows that viewing photo collages activates more brain regions than single images, improving memory recall by up to 43%. Interestingly, social media posts featuring photo collages receive 30% more engagement than single-photo posts.
Modern browser-based collage makers leverage the HTML5 Canvas API to manipulate pixel data directly. When creating a collage, images are first decoded into bitmap data, then resampled to appropriate dimensions using bilinear or bicubic interpolation algorithms. The layout engine calculates optimal positioning based on aspect ratios and selected templates, employing constraint-based systems to maintain visual balance. For circular crops, alpha channel masking applies transparency gradients at edges for anti-aliasing. Performance optimization techniques include progressive rendering for large collages and WebAssembly acceleration for image processing. The most sophisticated implementations use Web Workers to offload processing to background threads, preventing UI freezing even when handling multiple high-resolution images simultaneously.
A photo collage maker is a tool that allows you to merge multiple photos into a single image. You can create collages, grids, horizontal or vertical strips, and apply different shapes to your photos.
You can combine between 2 and 10 photos at once using our tool. This range provides flexibility for creating various types of photo compositions.
Our tool offers three main layouts: Grid (automatically arranges photos in a balanced grid), Horizontal Strip (places photos side by side), and Vertical Strip (stacks photos on top of each other).
Yes, you can choose between three shape options: Original (maintains the original photo shape), Square (crops photos to squares), and Circle (crops photos to circles).
Our tool supports the most common image formats including JPEG, PNG, GIF, and WebP. The combined photo is downloaded as a PNG file.
