1What is Image Quality Analyzer?

Get a complete technical profile of any image.

Image Quality Analyzer is part of the Pixly suite of professional image tools. It runs entirely in your browser with no software to install, requires no design experience, and delivers results in seconds — whether you are processing one image or an entire batch. Every operation is applied on the full-quality decoded image, so the output preserves the fidelity of your original file.

2How does Image Quality Analyzer work?

The analyzer decodes your image and produces a diagnostic report: exact pixel dimensions, aspect ratio, megapixels, file size, bits per pixel, detected MIME type, color depth (including palette detection), alpha-channel presence, average brightness, contrast ratio and dominant colors. EXIF metadata such as camera model, exposure and GPS presence is summarized as well.

Each measurement uses the decoded pixel buffer rather than trusting headers, so the report reflects the true content — a renamed or mislabeled file is flagged by comparing actual decoded format against its extension.
