About formats

JPEG is one of the most widely used image formats in computing, standardized by the Joint Photographic Experts Group and published as ISO/IEC 10918-1 in September 1992. The .jpeg extension is functionally identical to .jpg — both contain the same JFIF or Exif-wrapped JPEG compressed image data. The format applies lossy compression using the discrete cosine transform (DCT): images are divided into 8x8 pixel blocks, transformed into frequency coefficients, quantized to discard visually less significant information, and entropy-coded for storage. The quality-to-size tradeoff is user-selectable, with typical settings producing files 10-20 times smaller than uncompressed originals at visually acceptable quality. JPEG supports 8-bit grayscale and 24-bit color, with Exif metadata carrying camera settings, GPS coordinates, timestamps, and thumbnails. One advantage is absolute universality — JPEG is readable by every image viewer, web browser, operating system, camera, phone, and printer manufactured in the past three decades, making it the safest format for sharing photographic images with any recipient. The efficient compression of continuous-tone photographic content is another core strength: JPEG consistently produces compact files from camera sensors and real-world scenes where subtle color gradients dominate. While newer formats like WebP and AVIF achieve better compression ratios, JPEG's installed base is so vast that it remains the default output of digital cameras and the most common image format on the web.

WebP is an image format developed by Google, announced on September 30, 2010, designed to provide superior compression for web images in both lossy and lossless modes. The lossy mode is derived from the VP8 video codec's intra-frame coding (the same technology used in WebM video), applying block prediction, transform coding, and adaptive quantization to photographic content. The lossless mode uses a distinct algorithm combining predictive coding, color space transforms, backward reference to repeated pixel patterns, and entropy coding. WebP also supports alpha transparency in both modes — lossy WebP with transparency is unique among common web formats, offering semi-transparent images at much smaller sizes than PNG. The format supports animated sequences as well, providing a modern alternative to GIF with full-color support and dramatically better compression. One advantage is substantial file size reduction — lossy WebP produces images 25-35% smaller than JPEG at equivalent visual quality, and lossless WebP is typically 26% smaller than PNG, directly improving web page loading speed and reducing bandwidth costs. Universal browser support provides another key strength: Chrome, Firefox, Safari, Edge, and all mobile browsers now render WebP natively, achieving the broad adoption threshold needed for practical deployment. Google's core web infrastructure (Search, YouTube thumbnails, Gmail) uses WebP extensively, and the format is supported by major CDN platforms, CMS systems, and image processing services. WebP has established itself as the primary modern alternative to JPEG and PNG for web content.
