Image Analyzer, Every Card: Quality, Colours, EXIF, File Type (Free)

Every card of the free Image Analyzer on a real 30-megapixel Canon JPEG: the summary (6720 × 4480, 11.3 MB, progressive JPEG at quality 99), a quality score of 78/100 that shows its working, the histogram (0.74% crushed blacks) and exact per-channel statistics over all 30 million pixels, the palette and a 16.1:1 contrast pairing, the true file type from its own bytes, the camera and lens data, and advice that links straight to the tool that makes the file smaller. Plus a PNG named .jpg, caught. Nothing is uploaded.

The Image Analyzer, every card, on a real camera JPEG: a Canon EOS 5D Mark IV photo at 6720 × 4480, 11.3 MB. It runs the moment you drop the file. The summary gives dimensions, megapixels, format and encoding (a progressive JPEG at about quality 99). The quality score, 78 out of 100, shows its working: resolution, sharpness (variance of the Laplacian), noise, exposure and tonal range. The histogram reports crushed blacks and blown highlights, and the channel table is computed over every pixel, not a sample. The palette lists the main colours with their share and copies a hex code on click; the contrast card finds the best pairing (16.1:1, passes AAA). File type and integrity reads the bytes, not the name — a PNG saved as .jpg is caught — and lists the colour profile and metadata blocks. Camera and capture shows camera, lens, exposure and, when present, location. The advice card says what would make the file smaller and links to the tool that does it. Free analyses one image up to 25 MB; Pro takes 100 with a comparison table. Nothing is uploaded.
