A quality score tells you more than a histogram.
Most image viewers show you basic file information. This tool goes further: it analyses the actual pixel data to measure sharpness using a Laplacian variance method, estimates noise in smooth regions, checks for blown highlights and crushed shadows, and extracts the dominant colour palette. EXIF metadata, if present, adds camera, lens, and location data. The quality score combines these readings into a single number — useful for quickly assessing photos before editing, submitting to stock libraries, or preparing files for print.

Questions
How is sharpness measured?
Sharpness is measured using Laplacian variance, a standard autofocus quality metric. The Laplacian operator detects rapid changes in pixel intensity (edges), and the variance of those responses indicates how much edge detail is present. A blurry image has near-zero Laplacian variance; a sharp image has high variance. The score is influenced by both focus quality and image content — a correctly focused image of a plain wall will score lower than a correctly focused image of fine detail.
What is clipping?
Highlight clipping occurs when pixels are so bright that all three colour channels are at their maximum value (255, 255, 255), losing all detail in those areas. Shadow clipping is the opposite: pixels so dark that all channels are at zero. Both types of clipping are permanent data loss — no editing can recover that detail. The tool counts the percentage of pixels at either extreme, and the score reflects how much clipping is present.
What does the quality score measure?
The score combines five factors: sharpness (30 points), exposure (25 points), clipping (15 points), noise (15 points), and resolution (15 points). A score of 90 or above generally indicates stock-ready quality. 75 and above is print-ready. 60 and above is web-ready. Lower scores indicate technical problems worth addressing before sharing or submitting the image.
Why is EXIF data not shown for some images?
EXIF data is embedded in the image file by the camera or phone at the time of capture. PNG and WebP files often contain no EXIF data at all. JPEG files from older cameras, screenshots, or images that have been processed or re-saved with EXIF stripping will also show nothing. Some editing software removes EXIF on export, and social media platforms strip EXIF (including GPS data) for privacy reasons before serving images.
