WebP
Google's versatile format that does it all—transparency, animation, and superior compression.
WebP is a modern image format developed by Google specifically to speed up the web. It is a 'swiss army knife' format that combines the best features of JPEG (lossy compression), PNG (lossless compression and transparency), and GIF (animation) into a single, efficient package. WebP lossless images are typically 26% smaller than PNGs, while WebP lossy images are 25-34% smaller than comparable JPEGs. This significant size reduction helps websites load faster and consume less bandwidth, which is why it is strongly recommended by Google's PageSpeed Insights. After years of partial browser support, WebP is now universally supported across all modern browsers (Chrome, Firefox, Safari, Edge), making it the default choice for delivering optimized images on the web today.
WebP is based on the VP8 video codec (part of the WebM project). **Lossy WebP** uses predictive coding to encode an image, similar to how video keyframes are compressed. It predicts the values of pixels based on their neighbors and only encodes the difference (residual). It operates in the YUV color space. **Lossless WebP** uses advanced techniques like dedicated entropy codes for different color channels, 2D locality of backward reference distances, and a color cache of recently used colors. It operates in the RGBA color space. Uniquely, WebP supports 'lossy with transparency'—a feature JPEG lacks. This allows for transparent images that are significantly smaller than PNGs by applying lossy compression to the RGB channels while keeping the alpha channel sharp (or compressed).
Google announced WebP in September 2010 as a new open standard for lossy true-color graphics. It was derived from the VP8 video codec technology Google acquired from On2 Technologies. In 2011, Google extended the format to support lossless compression, transparency (alpha channel), and animation, effectively positioning it as a replacement for JPEG, PNG, and GIF simultaneously. Adoption was initially slow outside of the Chrome ecosystem. Firefox added support in 2019, and the final major holdout, Apple's Safari, added support in September 2020 (iOS 14 / macOS Big Sur). This universal support marked the turning point where WebP became safe to use as a primary format.
X BitMap
Images written as C source code.
XBM (X BitMap) is a unique image format that is actually a valid snippet of C source code. It defines an array of bytes representing a monochrome bitmap. Because it is code, it can be compiled directly into an application binary, which made it the standard for X11 icons and cursors.
An XBM file contains `#define` statements for width and height, and a static array of unsigned chars: `static unsigned char image_bits[] = { 0x00, 0xFF, ... };`. It supports only 1-bit color (black and white). Transparency works by defining a mask.
The original format for X Window System bitmaps (X10/X11). Used extensively in the 90s for the early World Wide Web (Mosaic browser) before GIF/JPEG took over.
