What is an Image Color Picker?
An image color picker is a free online tool that lets you click any pixel in a photo to get its exact color code — HEX, RGB, or HSL — instantly. It is an essential utility for web designers, developers, and content creators who need to identify exact colors from photographs, screenshots, logos, or UI mockups without installing any software.
How to Get a HEX Color Code From an Image
Using colorandsize.com to pick a color from an image is simple. Drag and drop your image into the upload area, or click to browse your files. Once the image loads, hover your cursor (or finger on mobile) over any area to preview its color in real time. Click any pixel to lock the color in, then copy the HEX code, RGB value, or HSL value with a single click.
How to Check Image Dimensions Online Free
Checking image dimensions with colorandsize.com requires no software. The moment you upload an image, the tool displays the exact width and height in pixels, the aspect ratio (e.g. 16:9 or 1:1), the file size, the file format, and whether the image is landscape, portrait, or square — all calculated instantly in your browser without any server processing.
How to Extract a Dominant Color Palette From a Photo
The dominant color palette extractor analyzes every pixel in your image and surfaces the 8 most prominent colors automatically. This is useful for brand identity work, matching design elements to a photo, or discovering the mood of an image. Each color swatch shows the HEX code and can be copied or downloaded as a full palette.
How to Resize an Image Online Free
The built-in image resizer lets you change image dimensions without any upload. Enter a target width and height (with an optional aspect-ratio lock), or pick a quick preset like 50%, 2×, or 1080p. Choose to export as PNG, JPEG, or WEBP — with a quality slider for lossy formats — then click download. The resized file is generated entirely in your browser.
