What is a JPG file?

JPG (or JPEG) is the most common image format for photographs, used by nearly every camera, phone and website.

PNG is a lossless image format that keeps every pixel intact and supports full transparency.

WebP is a modern image format from Google that offers both lossy and lossless compression plus transparency, at much smaller sizes than JPG or PNG.

GIF is a classic format best known for short looping animations and simple graphics, limited to a 256-color palette.

BMP is an uncompressed bitmap format from early Windows that stores raw pixel data, producing simple but very large files.

TIFF is a flexible, lossless format prized in photography, scanning and professional printing for its top image quality.

SVG is a vector format that stores images as math-described shapes, so they stay perfectly sharp at any size.

HEIC is the high-efficiency image format Apple uses by default on iPhones and iPads since iOS 11.

AVIF is a next-generation image format with outstanding compression, often beating WebP and JPG at the same quality.

ICO is the Windows icon format used for application icons and website favicons, able to hold several small sizes in one file.
