Image file format. An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed.

PostScript is a page description language run in an interpreter to generate an image. [6] It can handle graphics and has standard features of programming languages such as branching and looping. [6] PDF is a subset of PostScript, simplified to remove such control flow features, while graphics commands remain. [6]
JPEG (/ ˈdʒeɪpɛɡ / JAY-peg, short for Joint Photographic Experts Group) [2] 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 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
To convert a PDF to SVG with dvisvgm, run the following command: dvisvgm --pdf --output=file.svg file.pdf. If you want to make your SVG smaller, you can add --optimize=all to dvisvgm and additionally run the resulting SVG through svgcleaner to further shrink the file without perceptual quality loss.
