Image Analyzer

Upload any image and get a full read-out — dimensions, aspect ratio, file size, format and a click-to-copy palette of its most dominant colors, all read directly from the file.

What is the Image Analyzer?

This combines two related jobs into one page: basic image analysis and dominant color extraction. Dimensions and file size come straight from the decoded image and the File object your browser already has; the color palette is built by shrinking the image down, sorting every pixel into coarse RGB buckets, and reporting the eight buckets with the most pixels in them as swatches with their hex codes.

Common Use Cases

• Pulling the exact brand colors out of a logo or screenshot as hex codes
• Checking a photo's format, resolution and file size before using it on a website
• Building a quick color palette for a design project from a reference photo

How to Use the Image Analyzer

1. Upload any image file.
2. Review the dimensions, aspect ratio, file size and format in the stat boxes.
3. Scroll to the color palette and click any swatch to copy its hex code to your clipboard.

Frequently Asked Questions

How is the dominant color palette calculated?

Every pixel's color is rounded into one of a set of coarse buckets, the buckets are counted, and the eight most common ones are averaged and shown as swatches — a simple but effective histogram approach that needs no external library.

Does the palette include very rare colors?

No, only the most frequently occurring color groups are shown, so a single stray pixel of an unusual color won't appear as a swatch.

Is the file size accurate?

Yes, it's read straight from the uploaded file itself, not recalculated, so it always matches what your operating system reports for that file.

Because both the metadata and the palette are computed from the file you already have open, there's nothing to wait on and nothing sent anywhere else.
