SVG to PNG Conversion in Java using GroupDocs.Conversion Cloud REST API

Convert SVG to PNG using Java API.

SVG (Scalable Vector Graphics) is a type of image file format that is used for vector graphics. It’s based on XML and can be styled with CSS. Unlike raster graphics (e.g. JPEG, PNG), SVG graphics can be scaled without losing quality. PNG (Portable Network Graphics) is a raster image format that uses pixels to represent images. It supports lossless compression, which means that the quality of the image isn’t degraded when it’s compressed. In this article, we will explore a step-by-step guide on how to convert SVG to PNG in Java using REST API.

The following topics will be covered in this tutorial:
