Description	🔵 .png (Portable Network Graphics) The .png format is a raster graphics file format that supports lossless data compression. It was created as an improved and non-patented replacement for Graphics Interchange Format (GIF). PNG files are widely used on the internet due to their efficient compression and support for transparent backgroundsThey are ideal for detailed, high-quality images and graphics with a small file size, making them a popular choice for web designers and photographers.
Technical details	🔵 The `.png` The `.png` (Portable Network Graphics) format is a widely used image file format known for its lossless compression and ability to handle transparency. Here are some technical details about the .png format: Lossless Compression: PNG uses lossless compression, meaning that it preserves all the image data during compression. This is in contrast to formats like JPEG, which are lossy and discard some information for smaller file sizes. Bit Depth: PNG images can range from 1-bit (black and white) to 48-bit color. It also supports 16-bit grayscale images. Transparency Support: One of the key features of PNG is its support for alpha channel transparency. This allows for varying levels of transparency in the image, from fully opaque to fully transparent, which is particularly useful for web graphics. Color Palettes: PNG supports truecolor (16 million colors) as well as indexed-color images, which use a palette of up to 256 colors. This makes the format versatile for different types of digital images, including photographs and graphics. Interlacing: PNG offers an interlacing feature (Adam7 interlacing), which allows an image to be loaded progressively. This means that a low-resolution version of the image can be displayed while the full image is being downloaded, which was particularly useful in the early days of the internet when connection speeds were slower. File Structure: A PNG file consists of a header, followed by several chunks of data. These chunks include information like the image's dimensions, color depth, palette (if used), and the image data itself. Gamma Correction: The format supports gamma correction, enabling it to better handle differences in how different displays render color brightness. Metadata: PNG files can include metadata such as textual information (e.g., title, author, description) and can be extended with custom metadata. Popularity and Usage: Due to its features, PNG is very popular for web graphics, icons, and complex images like maps or artworks. It's also used in applications that require high-quality images or transparency. No Native Support for Animation: Unlike formats like GIF, the standard PNG format does not support animation. However, an unofficial extension known as APNG (Animated PNG) adds this capability. Browser and Software Support: PNG is widely supported by all modern web browsers and image editing software, making it a universally accessible format for images on the internet. The PNG format was developed as an improved, non-patented replacement for GIF and as an alternative to the then-proprietary JPEG format. Its balance of quality, support for transparency, and lossless compression makes it ideal for many uses in web and graphic design.

Description	🔵 .avif (AV Image File Format) The .avif format is an image file format that is designed to encapsulate AV (AOMedia Video ) encoded images. AVIF offers significant file size reduction compared to JPEG and PNG while maintaining high image quality. It supports high dynamic range (HDR) and wide color gamut (WCG) images, as well as features like lossy and lossless compression, transparency, and animation. AVIF is increasingly being adopted for web use due to its efficiency and superior image quality.
Technical details	🔵 The `.avif` (AV1 Image File Format) is an advanced image format with: - AV1 Codec Basis: Uses AV1 video codec for high compression and quality, outperforming JPEG/PNG in smaller sizes. - Efficient Compression: Intra-frame coding from AV1 ensures minimal quality loss, effective at low bitrates. - HDR/WCG Support: Displays a wide color range and detailed highlights/shadows with HDR and WCG. - Transparency: Manages transparency and varying opacity. - Color Profiles: Supports ICC, RGB, and YCbCr color spaces. - 8-bit and 10-bit Colors: Handles both, enhancing HDR content detail. - Compression Types: Provides lossless and lossy options. - Tile-Based Coding: Enables parallel processing and selective decoding with image tiling. - Metadata: Incorporates Exif and XMP data. - Streaming and Thumbnails: Optimized for adaptive streaming and thumbnail storage. - Browser Support: Gaining support in browsers like Chrome, Firefox, and image software. - Bandwidth Efficiency: High compression benefits web/mobile content by reducing bandwidth. - Royalty-Free: No licensing fees, promoting widespread use. `.avif` marks a significant improvement in image formats, enhancing compression, quality, and features, ideal for web and mobile contexts. The introduction of the .avif format represents a significant advancement in image technology, offering improvements in compression, image quality, and features over older formats, particularly in the context of web and mobile applications.
