Description	🔵 Portable Network Graphics, or .png, is a raster graphics file format. Simply put, it's a digital image format. PNG files are popular online because they use lossless data compression and support transparent backgrounds.
Technical details	🔵 Let's look at the technical details of the .png format: PNG compression is lossless, meaning that all the image data is kept during compression. This is different from JPEG, which uses lossy compression and loses some image information to make smaller files. PNG images can range from basic black-and-white (1-bit) to very detailed images with 48 bits of color. They also support 16-bit grayscale images. A key feature of PNG is its support for alpha channel transparency. This lets you create images with varying degrees of transparency, from completely opaque to completely transparent. This is very useful for web graphics. PNG supports a full range of colors (truecolor), allowing for up to 16 million colors. It also supports indexed-color images, which use a palette of up to 256 colors. In short, PNG files are widely used because of their efficient compression, support for many different color palettes, and the ability to handle various transparency levels. These features make them perfect for many web applications.

Category	🔵 images
Programs	🔵 Internet Explorer 🔵 Safari 🔵 Firefox 🔵 Google Chrome
Description	🔵 This format is employed to store bitmap images and enhances color and brightness performance. It combines exposures to accurately capture subtle shadow details and highlight brightly lit areas. HDR can combine multiple images with varying light intensities, resulting in high-quality images.
Technical details	🔵 The HDR file's pixel intensity can represent the full range of tones present in reality. Images can display a wide range of pixel intensities. HDR captures bright light and the darkest shadows, rendering colors in a lifelike manner. There are two methods to create HDR: by combining different images in a specific way or by using specialized sensor technology.
