What is an SVG file?
SVG (Scalable Vector Graphics) is an image format that describes shapes with math instead of pixels, so it stays sharp at any size. SVG files use the .svg extension, are written in XML text, and are ideal for logos, icons, and line art. Photos are a poor fit because they are made of pixels, not shapes.
Why SVG scales perfectly
A pixel image has a fixed grid, so enlarging it makes the pixels visible. An SVG stores instructions like lines and curves, which the browser redraws crisply at any size, from a favicon to a billboard.
When to convert an SVG
Some tools and social platforms do not accept SVG. Converting it to PNG or WebP gives you a pixel image you can upload anywhere, while keeping the original SVG for future edits.

Every tool runs in your browser. Your image never leaves your device.
Frequently Asked Questions
How do I open an SVG file?
Any web browser opens an SVG. To edit it you need vector software, and to upload it where SVG is not allowed, convert it to PNG first.
Can I convert a photo to SVG?
Not usefully. SVG is built for shapes and flat art, so a photo turned into SVG becomes huge and looks wrong. Keep photos as JPG, PNG, or WebP.
