If you work with web graphics, dashboards, or data reports, you’ve probably come across the need to turn SVG images into standard PNG files. Maybe you’re building a Python app that creates charts, icons, or visual reports. Whatever the use case is, converting SVG code to PNG is a task you’ll often need to handle.

In this guide, we’ll walk through how to easily convert SVG code and files into PNG format in Python using a reliable Python library built to render and process SVG files with exceptional accuracy.

What Is SVG Code, and Why Convert It to PNG?

SVG (Scalable Vector Graphics) is an XML-based format that’s great for creating crisp, two-dimensional visuals. Since it’s vector-based, an SVG image can scale to any size without losing quality, which makes it ideal for modern interfaces, data charts, and interactive web graphics.

But here’s the catch: while SVGs are flexible, PNGs are often more practical. Why?

  • PNGs work everywhere in all browsers, editors, and viewers.
  • They’re easy to share and embed in documents, presentations, or emails.
  • Raster images like PNG usually load faster in many apps and environments.

Simply put, converting SVG code to PNG helps ensure your visuals look sharp and consistent across every device and platform — even when vector support isn’t guaranteed.

Python Library to Convert SVG Code to PNG

Aspose.SVG for Python via .NET is a dedicated API for parsing, editing, and rendering SVG documents in Python applications. It lets you:

  • Convert SVGs to multiple formats, including PNG, JPEG, BMP, PDF, and XPS.
  • Load SVGs from strings, files, or URLs.
  • Control output image size, DPI, and background color.
  • Work entirely offline, no need for browsers or third-party renderers.

Before we jump into the code, make sure you have the library installed. You can download Aspose.SVG for Python directly from the official releases page, or you can easily add it using pip:

pip install aspose-svg-net

Convert SVG Code to PNG in Python

Let’s start by converting the SVG code stored as a string to a PNG image. This approach is ideal for dynamically generated SVGs, such as charts or diagrams received from an API.

Follow the steps below to convert the SVG code from a string to a PNG image:

  1. Load the SVG code as a string using the SVGDocument class object.
  2. Create an instance of the ImageRenderingOptions class and specify PNG as an output format.
  3. Create the ImageDevice to write the rendered output to a file.
  4. Render SVG to PNG using the document.render_to(device) method.

The following code example shows how to convert SVG code from a string to a PNG image using Python.

Convert SVG Code from File to PNG in Python

If you already have an SVG file saved on disk, you can convert it directly to PNG. This is useful for converting templates, icons, or exported vector graphics.

Follow the steps below to convert SVG code from a file to a PNG:

  1. Load an existing SVG file using the SVGDocument class object.
  2. Create an image rendering device with PNG format.
  3. Render and save the image.

The following code example shows how to convert SVG code from a file to a PNG image using Python.

Adjust Output Size and Quality

Sometimes you need to control the output dimensions, DPI, or scaling of the PNG. Aspose.SVG provides flexible options for this.

Follow the steps below to adjust output image size and quality:

  1. Define rendering options with custom width, height, or DPI.
  2. Pass the options while creating the rendering device.
  3. Render and save.

The following code example shows how to adjust output image size and quality while converting SVG code to PNG:

Convert SVG to PNG In-Memory using Python

You can render SVGs entirely in memory, which is perfect for web applications or cloud services. This approach avoids creating temporary files and is ideal for API responses.

Follow the steps below to convert SVG to PNG in-memory using Python:

  1. Create an SVG document from a string.
  2. Render to an in-memory stream.
  3. Use the PNG bytes directly (e.g., return via API).

The following code example shows how to convert SVG to PNG in-memory using Python:

Output:

Generated PNG size: 34732 bytes
