Converting Android VectorDrawable to SVG: A Step-by-Step Guide
In Android development, VectorDrawable is commonly used to define scalable graphics that can be drawn using XML. SVG (Scalable Vector Graphics), on the other hand, is a widely used image format for vector graphics that is XML-based. Sometimes, you may want to convert Android VectorDrawable into SVG format, especially when you need to use the vector graphic in web applications or other platforms that support SVG images.
This guide will walk you through the steps to convert Android VectorDrawable to SVG.

1. Introduction
VectorDrawables in Android are XML-based graphics that can scale to any screen size or resolution without losing quality. They are typically used for icons, logos, and other elements that need to be rendered in different sizes across various devices.
SVG is also a vector-based format, which makes it ideal for scalable graphics on web pages and across different applications. If you have an Android VectorDrawable and need to use it in a web or non-Android application, converting it to SVG can be an effective solution.
Let’s take a deeper look at both formats and how you can convert an Android VectorDrawable to SVG.
2. What is VectorDrawable in Android?
VectorDrawable is a resource in Android that describes vector-based images, which are defined in XML format. It uses paths, shapes, and other elements to describe the image content. VectorDrawables are highly scalable, making them perfect for displaying images across different screen sizes without losing quality.
A typical VectorDrawable in Android looks like this:
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"
android:viewportWidth="24"
android:viewportHeight="24">
<path
android:fillColor="#000000"
android:pathData="M12,2L2,22h20z" />
</vector>
In this example, the pathData defines the shape of a triangle.
3. What is SVG?
SVG (Scalable Vector Graphics) is a web-standard XML-based image format used to describe two-dimensional vector graphics. It is widely supported by modern web browsers, and you can manipulate SVG files using CSS and JavaScript, making it interactive and animatable.
An example of a simple SVG file is:
<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24">
<path fill="#000000" d="M12,2L2,22h20z"/>
</svg>
In this example, the structure and data are very similar to the VectorDrawable but follow the SVG syntax.
4. Why Convert VectorDrawable to SVG?
There are several reasons why you might want to convert an Android VectorDrawable to SVG:
- Cross-platform compatibility: SVG is supported by many web platforms and graphic design tools, making it useful for both web and mobile development.
- Consistency in designs: If you’re working on a cross-platform application, converting Android vector assets to SVG can help maintain consistent vector designs across Android, iOS, and web platforms.
- Editability: SVG files are more commonly used in design tools (like Adobe Illustrator and Figma), making them easier to edit and manipulate for designers.
5. Manual Method to Convert VectorDrawable to SVG
If you prefer a manual method to convert Android VectorDrawable to SVG, here’s how you can do it:
Step 1: Analyze the VectorDrawable
First, open the VectorDrawable XML file and understand the structure. You’ll see a <vector> element containing one or more <path> elements with a pathData attribute.
Step 2: Extract the Path Data
The most crucial part of the conversion is the pathData element inside the <path> tag. The pathData attribute defines the shape and structure of the vector graphic. Copy the pathData value and be ready to use it in your SVG.
Example of Android VectorDrawable <path>:
<path
android:fillColor="#000000"
android:pathData="M12,2L2,22h20z"/>
Step 3: Write the SVG Structure
Create an SVG file with the correct XML structure. Here’s a basic SVG template:
<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24">
<path fill="#000000" d="M12,2L2,22h20z"/>
</svg>
Step 4: Adjust the ViewBox and Dimensions
In your VectorDrawable, the viewportWidth and viewportHeight attributes define the canvas size for the vector. You’ll want to replicate this in the SVG by adjusting the viewBox attribute.
- viewportWidth maps to viewBox width.
- viewportHeight maps to viewBox height.
- The width and height attributes in SVG can be adjusted based on the size you want for the final image.
Step 5: Replace Path Data
Finally, copy the pathData from the VectorDrawable and paste it into the <path> tag of the SVG structure.
6. Using Online Tools for Conversion
If you prefer an easier approach, several online tools can help automate the conversion process from VectorDrawable to SVG. Here are a few popular ones:
- Android VectorDrawable to SVG Converter: Some websites allow you to upload your VectorDrawable XML file and convert it to an SVG file directly. Just upload the file and download the SVG output.
- Online SVG Editor/Convertor: There are multiple tools available that allow you to convert XML to SVG quickly. For instance, svg-edit is a popular tool for editing and converting vector formats.
Example of online tools:
- SVGOMG (https://jakearchibald.github.io/svgomg/)
- Vectr (https://vectr.com/)
Simply copy your VectorDrawable XML and paste it into the conversion tool to get the SVG output.
7. Considerations when Converting
While converting VectorDrawables to SVG, you should keep in mind the following considerations:
- Complexity: Some VectorDrawables may contain complex paths that don’t convert perfectly into SVGs, especially if the paths are intricate or use Android-specific attributes.
- Gradients and Filters: VectorDrawables in Android may use gradients, filters, or other advanced features that might not directly translate into SVG. In such cases, you might need to modify the SVG to properly render those effects.
- Dimensions: Ensure that the viewBox and size attributes are correctly adjusted to match the original dimensions of the Android vector.
8. Conclusion
Converting Android VectorDrawable to SVG is a straightforward process but requires attention to detail. You can either do this manually by extracting the path data from the VectorDrawable XML and embedding it into an SVG structure or use online conversion tools for a quicker solution.
Using SVG instead of VectorDrawables is especially useful if you plan to use the graphic across multiple platforms, such as web or iOS. It also makes the image easily editable with design tools like Adobe Illustrator or Sketch.
By following the steps outlined above, you can efficiently convert your Android vector images to SVG format, making them more versatile for different development environments.
