What is PNG vs SVG
What is PNG
PNG stands for Portable Network Graphics. It is a raster image format made of pixels. PNG is commonly used for images that need transparency, high quality, and detailed graphics like screenshots, UI designs, and logos with complex details.
PNG files are usually larger in size compared to JPG and WEBP because they store more image data. If you want to understand the difference between raster formats, read JPG vs PNG.
What is SVG
SVG stands for Scalable Vector Graphics. It is a vector image format made using mathematical paths instead of pixels. SVG images can be resized to any size without losing quality. SVG is mainly used for logos, icons, illustrations, and simple graphics.
SVG files are usually very small in size compared to PNG files when used for simple graphics.
Why It Is Important
Choosing between PNG and SVG is important because it affects:
- Website loading speed
- Image quality
- SEO performance
- Mobile performance
- Storage space
Large PNG images can slow down your website, while SVG images are usually very small and load faster. However, SVG is not suitable for complex images like photos.
You can reduce image size using proper compression methods. Read the Image Compression Guide to learn how to reduce image size without losing quality.
When to Use It
