PNG vs SVG — which should you use?
PNG and SVG are both popular image formats, but they're built for different jobs. PNG is a raster format — a grid of pixels with a fixed resolution. SVG is a vector format — math that describes shapes and scales infinitely. Choosing the wrong one is the most common source of pixelated logos in print.
- PNG (Portable Network Graphics): PNG is a raster format that stores an image as a grid of pixels. It supports lossless compression and transparency. PNG is great for screenshots, photos with transparent backgrounds, and any image that will be displayed at a fixed size on screen.
- Pixel-based (raster) format
- Lossless compression
- Supports transparency
- Fixed resolution — pixelates when scaled up
- Best for screen display at known sizes
- SVG (Scalable Vector Graphics): SVG is a vector format that stores an image as mathematical shapes. It scales to any size without quality loss. SVG is ideal for logos, icons, illustrations, and anything that needs to be printed at multiple sizes or edited later.
- Math-based (vector) format
- Scales infinitely without quality loss
- Editable in code or in Illustrator / Inkscape / Vectify
- Smaller file size for simple shapes
- Best for logos, icons, illustrations
- How to choose: Use PNG for photos, screenshots, and anything you'll only display at a fixed size on screen. Use SVG for logos, icons, brand marks, and anything that will be printed, used at multiple sizes, or edited later.
- Converting PNG to SVG: If you have a logo in PNG (especially one generated by ChatGPT, Midjourney, or another AI tool), you'll want to convert it to SVG before printing or scaling. Vectify uses an AI tracing model to convert PNG to clean SVG in seconds.
