The proportional relationship between an image's width and its height. Common ratios include 16:9 (widescreen) and 1:1 (square).
An uncompressed raster graphics format used to store digital images. BMP files are typically much larger than JPEGs but maintain perfect quality.
A web technology that allows for high-performance, scriptable rendering of 2D shapes and bitmap images directly in the browser.
A measure of spatial printing, video, or image scanner dot density. Higher DPI means higher resolution and detail when printed.
Metadata embedded in image files (like JPEG) that contains information about the camera settings, date, time, and sometimes GPS location.
A six-digit, three-byte hexadecimal number used in HTML, CSS, and other computing applications to represent colors (e.g., #FFFFFF for white).
A cylindrical-coordinate representation of colors that is more intuitive for humans than RGB. Hue is the color, Saturation is intensity, and Lightness is brightness.
A commonly used method of lossy compression for digital images, particularly for those produced by digital photography.
A class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data (e.g., PNG, TIFF).
A method of data encoding that uses inexact approximations and partial data discarding to represent the content, resulting in smaller file sizes (e.g., JPEG).
The electronic or mechanical conversion of images of typed, handwritten, or printed text into machine-encoded text.
A raster-graphics file format that supports lossless data compression and transparency. It was developed as an improved, non-patented replacement for GIF.
An additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors for screen displays.
An XML-based vector image format for two-dimensional graphics with support for interactivity and animation. Unlike JPG or PNG, SVG can be scaled to any size without losing quality.
A modern image format developed by Google that provides superior lossless and lossy compression for images on the web, often 25-30% smaller than JPEG.
These talking points translate technical definitions into reviewer-ready commitments for privacy, accessibility, and creative integrity.
