What image formats are supported?

This tool specifically supports JPG and JPEG image formats. For other formats like PNG or WebP, check out our other image conversion tools.

Is my image uploaded to a server?

No, all processing happens entirely in your browser using JavaScript. Your images never leave your device, ensuring complete privacy.

What data is included in the JSON output?

The JSON includes file information (name, size, type, last modified), dimensions (width, height, aspect ratio, megapixels), color statistics (average color, top 5 dominant colors with percentages), and format details.

How are dominant colors calculated?

The tool samples pixels from the image, groups similar colors together using color quantization, and returns the top 5 most frequent color groups with their percentage of the total image.

Can I use this for batch processing?

Currently this tool processes one image at a time. For batch processing, you can use the downloaded JSON format as a reference to build automated scripts using the same data structure.

What is the maximum file size supported?

The tool supports images up to 50MB in size. Larger files may take longer to process depending on your device's capabilities.
