# Photo Mosaic Generator Create stunning photo mosaics by combining hundreds of small images to form a larger main image. Each tile is carefully selected to match the colors of the underlying image. > Canonical page: https://elysiatools.com/en/tools/image-mosaic-generator - **Category:** Design - **Keywords:** mosaic, photo, tile, composite, art, collage, pattern, picture, 马赛克, 照片拼图, 拼贴艺术 ## Overview The Photo Mosaic Generator allows you to create stunning composite images by combining hundreds of small tile photos to reconstruct a single large main image. By analyzing and matching the colors of your tile images to the source image, the tool generates high-quality mosaic patterns with customizable tile sizes, blending modes, and resolutions. ## Inputs - **Main Image** (file): The large image that will be recreated with small tiles - **Tile Images (up to 500)** (file): Small images that will form the mosaic pattern - **Tile Size (px)** (number): Size of each mosaic tile (larger = fewer tiles, faster processing) - **Tile Analysis Resolution (px)** (number): Resolution for analyzing tile colors (lower = faster, higher = more accurate) - **Overlap Tiles** (checkbox): Tiles will overlap slightly for a more seamless appearance - **Blending Mode** (select): How tiles blend with the main image colors - **Output Format** (select) - **Quality (1-100)** (number): Output quality... ## When to use - Creating personalized anniversary or retirement gifts using a collection of family photos to form a main portrait. - Designing corporate branding materials or event posters that showcase community members or product catalogs in a single composite image. - Generating unique digital art and wallpapers from themed photo collections for social media or print. ## How it works - Upload your primary main image and select up to 500 small tile images to form the mosaic pattern. - Configure the tile size, analysis resolution, and choose whether to enable tile overlapping for a seamless look. - Select a blending mode (Normal, Tint, Overlay, or Screen) and set your preferred output format and quality. - Click generate to process the color matching and download the final high-resolution mosaic image. ## Use cases - Designing a commemorative poster for a school graduation using individual student portraits to form the school logo. - Creating a marketing banner for a brand using product catalog photos to reconstruct the company logo. - Producing custom wall art for home decor using travel photos to recreate a scenic landscape shot. ## Frequently asked questions ### How many tile images can I upload? You can upload up to 500 small tile images to build the mosaic pattern. ### What does the blending mode option do? It controls how the colors of the small tile images blend with the colors of the main image, offering options like Normal, Tint, Overlay, and Screen. ### How does tile size affect the output? Larger tile sizes result in fewer tiles and faster processing, while smaller tile sizes create a more detailed mosaic but take longer to generate. ### What file formats are supported for output? You can export your final photo mosaic in PNG, JPEG, or WebP formats. ### What is the maximum file size for the main image? The main image file size limit is 50 MB. ## Related tools - [Image Difference](https://elysiatools.com/en/tools/image-difference): Calculate the difference between two images to identify changes or create comparison masks - [Image Hue Adjustment](https://elysiatools.com/en/tools/image-hue): Adjust image hue to shift colors and create color effects - [Meme Generator](https://elysiatools.com/en/tools/image-meme-generator): Create classic memes by adding top and bottom text to images with Impact font style - [Image Multiply Blend](https://elysiatools.com/en/tools/image-multiply): Apply multiply blend mode between two images to create shadow effects and darken colors - [Image Negative Effect](https://elysiatools.com/en/tools/image-negative): Create photo negative effect by inverting all colors in the image - [Image Overlay Blend](https://elysiatools.com/en/tools/image-overlay): Apply overlay blend mode between two images to enhance contrast and create dramatic effects - [Image Saturation Adjustment](https://elysiatools.com/en/tools/image-saturation): Adjust color saturation levels to make colors more vivid or create grayscale effects - [Image Screen Blend](https://elysiatools.com/en/tools/image-screen): Apply screen blend mode between two images to create brighter, more luminous effects ## Samples - [Web Image Processing Python Samples](https://elysiatools.com/en/samples/web-image-processing-python): Web Python image processing examples using PIL/Pillow including reading, saving, resizing, and format conversion - [Web Image Processing TypeScript Samples](https://elysiatools.com/en/samples/web-image-processing-typescript): Web TypeScript image processing examples including image read/save, scaling, and format conversion - [Android Image Processing Java Samples](https://elysiatools.com/en/samples/android-image-processing-java): Android Java image processing examples including reading/saving images, scaling, and format conversion - [Android Image Processing Kotlin Samples](https://elysiatools.com/en/samples/android-image-processing-kotlin): Android Kotlin image processing examples including reading/saving images, scaling, and format conversion ## Related content - [Photo Color Adjustment and Artistic Filter Tools](https://elysiatools.com/en/hubs/photo-color-adjustment-and-artistic-filters): Adjust photo brightness, contrast, gamma, hue, saturation, temperature, tint, and vibrance, then apply artistic filters like grayscale, vintage, duotone, posterize, solarize, cross-process, infrared, emboss, and photo mosaic. - [Image Format Conversion and Animated Export Tools](https://elysiatools.com/en/hubs/image-convert): Compare image format converters for JPG, PNG, GIF, AVIF, WebP, TIFF, ICO, base64, and animation-friendly exports in one hub. - [Image Cleanup, Framing, and Batch Prep Tools](https://elysiatools.com/en/hubs/image-utility): Compare image cleanup, trimming, padding, framing, batch resize/compress, watermarking, and visual polish tools in one hub for asset preparation workflows. - [Image Metadata, EXIF, and Privacy Cleanup Tools](https://elysiatools.com/en/hubs/image-metadata): Compare image metadata viewers, EXIF/IPTC/XMP inspectors, orientation fixers, metadata editors, and privacy cleanup tools for photo publishing workflows.
