Color Picker from Image
Drop a screenshot or photo, click any pixel, and copy the HEX, RGB, or HSL value. Built for design QA, brand matching, and palette extraction.
Drop an image to pick colors
JPG, PNG, WebP, GIF — all stays in your browser
How to pick a color from an image online
Drop a JPG, PNG, WebP, or GIF into the upload area. The image is decoded into a canvas in your browser — no upload to any server. Move your cursor over the image to preview the pixel under the crosshair, then click to lock the pick. HEX, RGB, and HSL appear in the side panel with one-click copy buttons. Each click also stacks the color into a Recent picks row, so you can build a palette out of a single image.
Why a local color picker matters
Designers regularly pick colors from confidential mockups, customer-supplied assets, or screenshots of competitor products. Uploading any of those to a third-party tool is a needless data leak — and slower than a local read. ToolChop runs the picker entirely in your browser, so the image never leaves your machine and there is no roundtrip latency between click and color.
What you can do
- Pick HEX, RGB, and HSL from any pixel
- Live hover preview before locking the click
- Build a palette via the Recent picks row (up to 12 swatches)
- Read pixel values at the image's native resolution
- Works with JPG, PNG, WebP, GIF, BMP, AVIF, and HEIC (browser support permitting)
Frequently asked questions
How do I pick a color from an image online for free?
Drop your image into the upload area on this page. Move your mouse over it for a live color preview, and click any pixel to lock the pick. HEX, RGB, and HSL values appear instantly — copy whichever format your design tool expects. No account, no upload to a server.
Does ToolChop upload my image?
No. The image is decoded into a canvas element in your browser, and ToolChop reads pixel values locally using Canvas getImageData. The file never leaves your device — there is no upload, no temporary storage, and no server copy. That matters when you are picking colors from internal mockups, screenshots of competitor sites, or branded assets you are not allowed to share.
What color formats are supported?
HEX (#RRGGBB), RGB (rgb(r, g, b)), and HSL (hsl(h, s%, l%)). All three are computed from the same source pixel, so the values are mathematically equivalent — just different notations for the same color.
Why is HSL useful when most tools use HEX?
HSL (Hue, Saturation, Lightness) is the format used by Tailwind CSS color tokens, modern design systems, and CSS custom properties for theming. Reading colors as HSL makes it easy to derive light/dark variants by adjusting only the L value, which is much harder in HEX or RGB.
Can I pick multiple colors to build a palette?
Yes. Every click adds the picked color to the Recent picks row (up to 12 colors). You can click any swatch to re-display its values, copy them, and build a palette out of a single image — useful for matching brand colors across mockups.
What about the EyeDropper API in Chrome?
Chrome's built-in EyeDropper API picks colors from anywhere on screen but requires the user to invoke a system overlay. ToolChop's picker is purpose-built for picking from a specific image: you get cursor-precision pixel coordinates, scaled-canvas accuracy, and a recents palette — none of which the browser eyedropper provides.
Why is the color I pick slightly different from what I see?
Two reasons. First, your monitor and OS may apply a color profile (sRGB vs Display P3) that shifts the rendered color from the file's underlying RGB bytes. Second, JPEG compression smooths colors across regions, so adjacent pixels can vary slightly. ToolChop reports the raw underlying RGB value, which is what your CSS or design tool will produce.
Does the picker work with transparent PNGs?
Yes. The picker reads each pixel's red, green, blue, and alpha channels. Transparent areas show as their underlying RGB (often black or white depending on how the file was authored), but the HEX value is still accurate for compositing.
Is there a file size limit?
Browsers usually decode up to ~150 megapixels without trouble. For very large images, the canvas is scaled down to ~900 px wide for display, but the picked color is read from the original-resolution pixel — there is no quality loss in the readout.
Can I pick colors from a screenshot?
Yes — screenshots are the most common use. Drop a screenshot of a website, an app UI, or a Figma export, and the picker gives you the exact HEX values devs need to recreate the design. This is the standard workflow for design QA against a competitor's product.
What image formats does it support?
Any image format your browser can decode: JPG/JPEG, PNG, WebP, GIF, BMP, and modern formats like AVIF on Chrome 85+ and HEIC on Safari 17+. Animated GIFs and WebPs show the first frame.
Why use ToolChop instead of an online color picker that uploads my image?
Privacy and speed. Designers often pick colors from confidential mockups, customer-supplied assets, or competitor screenshots — uploading any of those to a third-party tool is a needless data leak. ToolChop runs entirely in your browser so the image never leaves your machine. There is also no roundtrip latency: the moment you click, you have the color.
