SVG is an XML-based image format that describes shapes with math instead of pixels, so it stays sharp at any size and any screen density.
Also called: Scalable Vector Graphics · .svg
SVG files are plain text: paths, circles, rectangles, gradients, and text nodes wrapped in <svg>. That makes them easy to edit in a code editor, style with CSS, and animate with JavaScript or SMIL.
They're ideal for logos, icons, illustrations, and charts — anything vector. They're not suitable for photographs, which need raster formats like JPEG or WebP.
Because SVG can contain scripts, treat SVGs from untrusted sources like any other user-supplied HTML: sanitise before rendering inline.
OCR is a technology that turns pictures of text — scans, photos, screenshots — into real, editable, searchable text characters.
EXIF is metadata embedded in image files — camera model, exposure settings, date, and often GPS coordinates of where the photo was taken.
WebP is a modern image format from Google that compresses photos and graphics roughly 25–35 % smaller than JPEG or PNG at the same visual quality.
