SVG vs PNG -- Vector or Raster?

Two completely different image types for two different jobs. Here is how to choose.

What is SVG?

SVG (Scalable Vector Graphics) is a vector format that describes images using mathematical shapes -- lines, curves, and polygons. Because SVG is resolution-independent, it looks sharp at any size, from a 16px favicon to a billboard. SVG files are XML-based text files, which means they can be edited with code, styled with CSS, and animated with JavaScript.

What is PNG?

PNG (Portable Network Graphics) is a raster format that stores images as a grid of colored pixels. It uses lossless compression, so quality is preserved perfectly. PNG supports full transparency (alpha channel), making it the standard format for graphics, screenshots, and images with transparent backgrounds. However, PNG files are resolution-dependent -- scaling up causes blur.

Key differences

FeatureSVGPNG
TypeVector (math-based)Raster (pixel-based)
ScalingInfinite, always sharpBlurs when enlarged
File size (simple graphics)Very small (1-10 KB)Larger (10-100 KB)
File size (complex images)Can be very largePredictable
TransparencyYesYes (alpha channel)
PhotosNot suitablePossible but large
Editable with codeYes (XML/CSS/JS)No
AnimationYes (CSS/JS/SMIL)No (APNG has limited support)

When to use SVG

When to use PNG

Convert and optimize

If you have a PNG logo, consider converting it to SVG using a vector editor (Figma, Inkscape, Illustrator). For PNG images that need to be compressed or converted, use our tools: PNG to JPG | JPG to PNG | Image Compressor

Frequently asked questions

Can I convert PNG to SVG?

Automated conversion (tracing) works for simple graphics like logos but produces poor results for photographs or complex images. For best results, recreate the graphic in a vector editor like Figma or Inkscape.

Which is better for web: SVG or PNG?

For logos, icons, and simple graphics, SVG is better -- smaller file size and infinite scalability. For screenshots, photos with transparency, and complex raster images, PNG is the right choice.

Do all browsers support SVG?

Yes. SVG has been supported by all major browsers since 2011. It is safe to use for any web project without fallbacks.
