Are my images uploaded to a server?

No. Images are processed locally in your browser using canvas, so they are not uploaded to our servers.

Can I crop a screenshot without losing quality?

Yes. The crop tool maps your selection back to the original image pixels before exporting the result.

Which colour formats does this tool export?

The picker shows HEX, RGB, and HSL values for the selected pixel.

Image color picker and local screenshot cropper

This tool helps designers, developers and content creators read exact colors from an image and crop a selected area of a screenshot. The main workflow runs in your browser with the HTML5 Canvas API, so typical image picking and cropping does not require uploading the file to a server.

Color formats available

When you click a pixel on the image, the tool shows the selected color in common web formats:

HEX: commonly used in CSS, design systems and brand guidelines, for example #3B82F6.
RGB: useful when you need red, green and blue channel values or want to create an rgba() color.
HSL: useful for adjusting hue, saturation and lightness when building related colors.

Local palette history

The recent palette keeps your last selected colors on the page so you can compare nearby tones and copy values again without reopening the image.

Frequently asked questions

Are my images uploaded?

The picker and cropper use browser canvas processing. For normal use, the selected image is rendered locally in your browser and is not sent to Mini-Tools.uk.

Does cropping reduce quality?

The crop export maps your selection back to the original image pixels, so the downloaded PNG uses the source image area rather than a low-resolution screen preview.
