What is SVG?
SVG is a vector format for logos, icons and illustrations. Here is how it works, where it is used and how to get a PNG for a website, presentation or messenger.

What is SVG
SVG (Scalable Vector Graphics) is a vector format based on XML. The image is described by geometry, curves and colours rather than pixels. That is why SVG can be scaled up without quality loss.
Where SVG is used
- logos and icons;
- diagrams and infographics;
- interface elements;
- website illustrations;
- favicons in modern browsers.
For a logo, SVG is often more convenient than PNG: it scales and takes little space. But for print, older editors and some services, a raster format is needed.
How to convert SVG to PNG
The browser opens the SVG as an image, draws it on a canvas and saves it as PNG. A transparent background is preserved. If the browser fails, server-side processing with sharp rasterises it.
Our SVG to PNG converter is suitable for websites, presentations and messengers. SVG to AVIF is an option for a modern website with less weight.
Limitations
PNG is a raster format: after conversion the image cannot be enlarged indefinitely without quality loss. For large print sizes, prepare an SVG at the required dimensions or keep the vector original.
Questions and answers
Why is SVG better than PNG?
SVG scales without quality loss and is often smaller for logos and icons. PNG is a raster format and depends on resolution.
Why does SVG not open in some apps?
SVG is a text format based on XML. Not every editor and service supports it as an image, so PNG is sometimes required.
What size will the PNG be?
SVG is rasterised at its natural size. For a large PNG, prepare an SVG at the required dimensions.
Can I use SVG as a favicon?
Yes, modern browsers support SVG favicons. For older browsers and Windows, create an ICO from PNG.
