SVG: the vector format for the web

SVG stands for Scalable Vector Graphics and is a file format for two-dimensional images based on vectors. Unlike pixel images such as JPG and PNG, an SVG describes shapes, lines and colours using mathematical formulas. This makes SVG ideal for logos, icons and illustrations that need to look sharp at any screen size.

How does an SVG file work?

An SVG file is essentially a text file written in XML code. Every shape, line and colour is described with coordinates and parameters. If you open an SVG in a text editor, you will see code such as ''. The browser reads this code and draws the image in real time. Because it uses mathematical descriptions rather than fixed pixels, the image can be scaled to any size without loss of quality.

Benefits of SVG

Infinitely scalable

An SVG file remains razor-sharp at any size. Whether it is a small favicon or a full-screen background, the quality stays identical. This makes SVG perfect for responsive websites viewed on all kinds of devices.

Extremely small file size

SVG files are typically much smaller than comparable PNG or JPG files, especially for simple images such as logos. This results in faster loading times and better website performance.

Editable with code

Because SVG is based on XML, you can adjust colours, dimensions and animations with CSS and JavaScript. This enables interactive hover effects, animations and dynamic colour changes without additional images.

SVG compared with raster formats

Raster images (JPG, PNG)

Raster formats consist of a fixed grid of pixels. When enlarged, the pixels become visible and the image turns blurry. Each size requires a separate file. The file size increases as the resolution gets higher.

SVG (vector format)

SVG files are resolution-independent and always remain sharp. A single file works at all sizes and on all devices. The file size is small and constant, regardless of display size. Moreover, the content is searchable by search engines.

When should you use SVG?

Logos on websites

SVG is the best format for logos on websites. It is sharp on every screen, lightweight and easy to customise. Major companies such as Google and Apple use SVG for their web logos.

Icons and illustrations

Icon sets and simple illustrations are ideal as SVG. They load quickly, scale effortlessly and can be styled with CSS — for example, changing colour on hover.

Infographics and diagrams

Interactive charts, diagrams and infographics benefit from SVG because elements can be animated with JavaScript and the image remains legible at any size.

Animations

SVG supports animations via CSS and JavaScript (SMIL). This lets you create smooth animations such as spinning logos, moving illustrations or interactive loading screens — without heavy video files.

Frequently asked questions about SVG

Is SVG suitable for photos?

No, SVG is not suitable for photos or complex images with gradients and textures. JPG and PNG are better options for those. SVG is ideal for logos, icons and illustrations with flat colours and sharp lines.

Is SVG supported by all browsers?

Yes, all modern browsers fully support SVG, including Chrome, Firefox, Safari, Edge and mobile browsers. Only Internet Explorer 8 and older do not support SVG, but these browsers are hardly used any more.

How do I create an SVG file of my logo?

You can create an SVG in vector programs such as Adobe Illustrator or the free Inkscape. Only have a pixel image? Then the logo must first be vectorized. Logo in Vector does this professionally and delivers an SVG file among other formats.

Is SVG safe to use on my website?

SVG is safe provided you use files from trusted sources. Because SVG can contain JavaScript, it is important to sanitize SVG files from unknown sources. If you create your own SVGs or receive them from a trusted party like Logo in Vector, there is no risk.

SVG: essential for modern websites

SVG is the standard format for logos and icons on the web. It combines scalability, speed and flexibility in a way no raster format can match. Need an SVG of your logo? Logo in Vector delivers an optimized SVG file ready for immediate use on your website.
