Aspect Ratios & Megapixels

Aspect ratio defines the proportional relationship between image width and height. Megapixels (MP) measure total sensor resolution (1 MP = 1,000,000 pixels). For example, a standard 1080p image is 1920×1080 = 2.07 MP with a 16:9 ratio.

DPI / PPI & Print Sizing

DPI (Dots Per Inch) tells printers how many pixels to lay down per inch. On screen, pixel count alone dictates display size; DPI metadata only affects physical print output. If no DPI header is embedded, "Not available" is reported.

100% Client-Side Privacy

All dimension calculation and header metadata extraction happens directly inside your browser sandbox using the File API. Your images are never uploaded, stored, or transmitted to any external server.
