What Is an SVG File? Format, Uses and How to Open One

Updated October 12, 2026 · 2 min read

SVG stands for Scalable Vector Graphics. It is an image format that describes shapes with text, so it stays sharp at any size.

What is inside an SVG

Open one in a text editor and you will see readable code: a width and height, then elements such as paths, circles and rectangles with fill colors. A browser reads that code and draws the picture. That is why SVG files are small for simple graphics and can be edited with ordinary tools.

Where SVG is used

Logos and icons on websites
Design work in Illustrator, Inkscape, Figma and Canva
Cutting machines such as Cricut and Silhouette
Laser engraving and CNC software, often after converting to DXF

How to open an SVG

In a browser: drag the file into a tab. It will display at any zoom.
In a design tool: open it in Illustrator, Inkscape or Figma to edit shapes and colors.
In a text editor: to read or tweak the code.

SVG versus other formats

PNG and JPG are pixel formats, so they blur when enlarged. SVG does not. See PNG vs SVG for when to use which.

Some software wants DXF instead, especially CAD and laser tools. You can go from one to the other with SVG to DXF.

Limits to know

SVG is best for flat graphics. It can hold a photo, but only by embedding a pixel image inside, which defeats the point. Text in an SVG depends on fonts unless it has been converted to outlines, so outline your text before sending files to a printer or cutter.
