Upload your main photo and tile images — mosaic generates automatically
Choose the photo you want to turn into a mosaic. This is the "big picture" that will be recreated using smaller tile images.
Upload multiple smaller photos that will be used as the building blocks of your mosaic. The more tiles you add (50+), the better the color matching and final result.
Control tile size, blending opacity, tile shape (square, circle, or hexagon), color matching algorithm, and output quality to customize your mosaic.
Click Generate Mosaic and watch your photo come to life. Download the result as JPEG, PNG, or WEBP instantly - no watermarks, no sign-up.

A photo mosaic (also called a photomosaic or picture mosaic) is an image that has been divided into smaller sections, each of which is replaced by another photograph. When viewed from a distance, the individual tile photos blend together to reveal the original large image - a fascinating visual illusion that makes mosaics both artistic and deeply personal.
Photo mosaics are popular for wedding gifts, anniversary presents, family photo walls, sports team tributes, graduation gifts, and memorial artwork. They transform a collection of memories into a single powerful image.
Yes, PicDriver's Photo Mosaic Generator is completely free. There are no hidden fees, no watermarks, and no account registration required. Just upload, generate, and download.
We recommend a minimum of 20 tile images, but 50–200 tiles will produce the best results. More tiles with a wider variety of colors allows the algorithm to better match each section of your main image.
Absolutely. All processing happens entirely in your browser. Your photos are never uploaded to any server. PicDriver cannot access your images at any point.
You can download your photo mosaic as JPEG (best for sharing and social media), PNG (lossless quality, larger file size), or WEBP (modern format with excellent compression and quality).
Yes! For best print results, use the High quality setting and PNG format. The output resolution scales with your main image size and chosen quality level. For large prints (poster size), use a high-resolution original photo.
The generator analyzes thousands of individual tile positions and finds the closest-matching tile image for each. Larger images with smaller tile sizes require more comparisons. Use "Fast" quality mode for quicker results, or "High" for best quality.
