A measure of spatial printing or display resolution, representing the number of individual dots that can be placed in a line within the span of one inch.
An additional channel in an image that stores transparency information, allowing parts of an image to be completely or partially transparent.

A raster graphics file format that supports lossless data compression and transparency. Ideal for images with sharp edges, text, or transparency needs.
An XML-based vector image format for two-dimensional graphics. Scales to any size without losing quality and can be animated or interactive.
A modern image format developed by Google that provides superior lossless and lossy compression for web images, supporting animation and transparency.
A flexible, adaptable file format for handling images and data, commonly used in publishing, photography, and professional printing.
An approach to web design that makes web pages render well on a variety of devices and window or screen sizes, ensuring optimal viewing experience.
