In comparison, when storing images that contain text, line art, or graphics – images with sharp transitions and large areas of solid color – the PNG format can compress image data more than JPEG can. Additionally, PNG is lossless, while JPEG produces visual artifacts around high-contrast areas.
The PNG, JPEG, and GIF formats are most often used to display images on the Internet. Some of these graphic formats are listed and briefly described below, separated into the two main families of graphics: raster and vector.
Comparison of graphics file formats. This is a comparison of image file formats (graphics file formats). This comparison primarily features file formats for 2D images .
If a diagram cannot be produced in SVG, then a PNG image is preferred over a JPEG. The PNG compression algorithm is designed to work with large areas of solid colour that have sharp boundaries. It is therefore a good format for diagrams and cartoons.
JPEG (/ ˈ dʒ eɪ p ɛ ɡ / JAY-peg, short for Joint Photographic Experts Group) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
JPEG XL – an image file format developed since 2019 (standardization completed since 2022) and based on Google PIK [Wikidata] and Cloudinary FLIF (itself based upon FUIF [Wikidata]) claiming to outperform PNG, WebP, BPG and JPEG 2000 for lossless encoding at least
Format conversion: convert an image from one format to another (e.g. PNG to JPEG). Transform: resize, rotate, crop, flip or trim an image. (Applies these without generation loss on JPEG files, where possible.) Transparency: render portions of an image invisible. Draw: add shapes or text to an image. Decorate: add a border or frame to an image.
The Exif specification also includes a description of FPXR (FlashPix-ready) information, which may be stored in APP2 of JPEG images using a structure similar to that of a FlashPix file. These FlashPix extensions allow meta-information to be preserved when converting between FPXR JPEG images and FlashPix images.
JPEG is good for images where the color changes fluidly throughout the image, like in a photograph, whereas PNG files are good for images with relatively few colors, such as a drawing of a flag, a chart, or a map; note that sometimes SVG is better.
Converting an image or audio file in a lossy format (like JPEG or Vorbis) to a lossless (like PNG or FLAC) or uncompressed (like BMP or WAV) format only wastes space, since the same image with its loss of original information (the artifacts of lossy compression) becomes the target.
