Free Image Analyzer: Extract Colors, Dimensions & Metadata Online
Our free online image analyzer lets you extract detailed information from any image directly in your browser. Upload a photo, screenshot, or graphic to instantly discover its dimensions, file size, format, aspect ratio, and dominant color palette. Everything runs locally on your device with zero uploads to external servers.
The dominant color extraction feature uses Canvas API pixel sampling to identify the top 5 most prominent colors in your image. Each color is displayed with its hex code, RGB value, and approximate percentage. Click any color swatch to copy the hex code to your clipboard, making it easy to use in your design workflow.
Beyond color analysis, the tool provides comprehensive image metadata including exact pixel dimensions, megapixel count, file size in human-readable format, MIME type, and calculated aspect ratio. This information is essential for web developers optimizing images, designers checking specifications, and content creators ensuring their visuals meet platform requirements.
Whether you are a graphic designer extracting a color palette from an inspiration image, a web developer checking image dimensions for responsive layouts, or a photographer reviewing file metadata, this tool provides instant, accurate results without any software installation or account signup.
