SVG vs PNG: 7 Key Differences and Full Comparison

SVG and PNG are two of the most commonly used image formats on the web. Understanding the key differences between SVG and PNG can help you make informed decisions when it comes to using them in your projects. SVG provides resolution-independent graphics and is best suited for graphics that don’t require a high level of detail.

On the other hand, PNG is a lossless format and provides higher-quality images with a wider range of color depths. Both formats have their own unique strengths, and choosing between them often comes down to the specific requirements of your project. In this article, we’ll take a closer look at the full comparison of SVG vs. PNG.

SVG vs PNG: What’s the Difference?

Both formats are widely used for web graphics, but they have distinct features that make them better suited for different situations. Let’s compare SVG vs. PNG and break down their key differences.

Transparency

svg vs png
SVG images are defined in a vector graphics format and stored in XML text files.

SVG supports transparency through the use of a transparent element or an alpha channel. The transparency element in an SVG can be set to a specific percentage, making it possible to have partial transparency.

This can be particularly useful in designs where you want to show objects in the background while still being able to see the objects in the foreground. For example, if you’re creating a logo with a transparent background, you can easily create this effect in an SVG.

On the other hand, PNG also supports transparency. Unlike SVGs, PNGs use an alpha channel to create transparency. This means that the transparency effect is binary; either the object is transparent, or it isn’t.

PNGs are commonly used in web design because they support 8-bit transparency, making them ideal for transparent images or logos that need to be used in a web context. However, if you want to create a design with partial transparency, you won’t be able to do this in a PNG file.

Animation

SVGs are perfect for animation because they are vector-based, meaning they are made up of vector graphics describing the shape and size of objects in the image. This makes it possible to animate an SVG by changing the values of these equations.

For example, you can create an animation that moves a shape from one side of the screen to the other, or one that changes the size and shape of an object over time.

PNGs, on the other hand, are not ideal for animation because they are bitmap-based, meaning that they are made up of pixels. This makes it much more difficult to animate a PNG because you have to change the individual pixels in the image. While it is possible to animate a PNG, it’s much more time-consuming and not as easy as animating an SVG.

Complexity and Compatibility

SVGs are ideal for complex designs because they are vector-based, making it easy to add, change or remove elements from the design. Additionally, because SVGs are written in XML, they are compatible with most web browsers and can be easily edited in software like Adobe Illustrator.

PNGs, on the other hand, are bitmap-based, making them ideal for simpler designs. While it is possible to add elements to a PNG, it can be difficult to make changes without losing quality or creating pixelation.

Additionally, because PNGs are a type of image file, they may not be compatible with all web browsers and may not be as easily edited as an SVG.

Web Use

SVGs are ideal for use on the web because they are scalable and can be resized without losing quality. Additionally, they are lightweight and won’t slow down the loading time of a website. This makes SVG perfect for logos, icons, or graphics that need to be used in a web context.

PNGs are also commonly used on the web but are better suited for images that need to maintain their quality and clarity when resized. PNGs are ideal for images with large areas of color, such as photographs, because they support lossless compression. This means they won’t lose quality when compressed.

Photography

PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF).

Unlike PNG or JPEG files, SVGs don’t use pixels to make up the image but, instead, use mathematical equations to create shapes and lines. This makes SVG perfect for logos, icons, and graphics that need to be scalable without losing any detail.

PNG files use pixels to create images, which makes them a great choice for photographs and other high-resolution images. However, PNG files are not ideal for scalable images because of their pixel-based nature, as they will become blurry and pixelated when resized.

Compression 

SVGs benefit from lossless compression, meaning that the image quality is not lost during the compression process. This makes it ideal for graphics and logos that need to maintain their crisp, clean look, even when used in a smaller size.

PNG files also use lossless compression, which is what makes them so well-suited for photographs and other high-resolution images.

File Sizes

SVGs are far smaller in size than PNGs, making them ideal for use on websites and other online applications. This is because SVGs use vector graphics to create images, rather than pixels, which reduces the file size considerably.

PNG file sizes can be large, particularly for high-resolution images. This is because PNG files use pixels to create images, which increases the file size. If you’re using high-resolution images on your website or online application, using PNG files can slow down the load time, causing a negative impact on the user experience.

SVG vs PNG: 9 Must-Know Facts

  1. SVG images can be resized without losing quality, while PNG images will pixelate when resized.
  2. SVG images are best for logos and icons due to their scalability, while PNG images are best for photographs and images with many colors.
  3. SVG images are smaller in file size compared to PNG images with similar dimensions.
  4. All modern browsers support SVG images, while some older browsers may not support PNG images.
  5. SVG images can be edited and animated in code, while PNG images are static images.
  6. PNG images support transparency, while SVG images can also have transparent backgrounds with some limitations.
  7. PNG images are better for images with large blocks of solid color and text, as they support lossless compression.
  8. SVG images can be compressed further with Gzip compression, making them more efficient for websites.

SVG vs PNG: Which One Is Better?

When it comes to choosing between SVG and PNG, the decision ultimately depends on the specific use case. But if we had to pick a winner, it’d be SVG.

SVG is a vector-based image format that is optimized for use on the web. It’s perfect for graphics with simple shapes and lines, such as logos and icons. Because it’s vector-based, it can be scaled up or down without losing quality, making it ideal for responsive design.

PNG is a raster-based image format that is best for images with complex details and gradients, such as photographs. It’s lossless, which means it doesn’t lose quality when edited. But when it comes to scaling, it doesn’t hold up as well as SVG.

SVG also has the advantage of being smaller in file size compared to PNG, meaning faster load times for your website. Plus, it can be animated and styled with CSS, making it more versatile.

In conclusion, while PNG is great for images with complex details, SVG is the clear winner for graphics that need to be scalable and optimized for the web. Don’t hesitate to use both formats where appropriate, but make sure to choose SVG for graphics that need to be scalable and optimized for the web.
