Scalable Vector Graphics (SVG) is a popular vector file format for graphics that includes built-in support for animation.
SVG images' main highlights are:
There are many advantages to using SVG images on the web. They are resolution independent, meaning they can be scaled to any size without losing quality. Since SVG is an open standard developed by W3C, modern browsers like Mozilla Firefox, Opera, Apple Safari, and Google Chrome can display these types of images natively. Also, as mentioned, they can be printed at any resolution and edited with vector design tools.
However, there are also a few disadvantages to using SVG format. Its support is not as extensive as that of raster image formats, which means that while modern browsers can display SVG images, older browsers may not. Different development platforms and libraries may interpret SVG features differently and even have very limited or no SVG support. Also, SVGs cannot be used for complex images with lots of detail, such as photographs.
Portable Network Graphics (PNG) is a raster image format popular for its high image quality, and versatility. To a large extent, this is because it supports lossless data compression. Since PNG was developed as an improved replacement for the GIF format, it is not surprising all major web browsers support PNG.
PNG images' main highlights are:
Using PNG images on the web could be advantageous. For one thing, PNGs are lossless, meaning their quality doesn't degrade when compressed. In addition, they are more flexible than SVGs, meaning you can use PNGs in more ways.
However, using PNG images also has its drawbacks. For example, they are not scalable as the SVG image format, meaning they cannot be printed at high resolutions. Also, since they contain a lot of pixel data, PNGs are often far larger than SVGs.
It's not fair to say that one format is better than the other since they are designed with different goals in mind. Graphic designers often prefer PNG due to its versatility. That said, SVG is a popular format for icons, logos, minimalistic graphic designs, and fonts because of its scalability and unique properties.
There are many ways to convert from SVG to PNG. For instance, you may use a program such as Adobe Photoshop for that purpose. However, instead of paying for proprietary software, a better way to convert from SVG to PNG is using a free online converter such as svgtopng.com.
