SVG vs PNG: Vector or Raster for Your Graphics?
SVG is resolution-independent code that scales to any size and stays tiny for simple graphics. PNG is fixed-resolution pixels ideal for detail and screenshots. How to do it to choose.
SVG and PNG solve the same problem, displaying a graphic, in fundamentally different ways, and understanding that difference is the whole decision. PNG is a raster format: it stores a fixed grid of pixels, so a PNG has one native resolution and gets blurry or blocky when scaled up. SVG is a vector format: it stores the graphic as math (points, lines, curves and fills described in text) so it renders razor-sharp at any size, from a 16-pixel favicon to a billboard, from the same tiny file.
That makes the choice mostly about what the image contains. For logos, icons, illustrations and anything built from clean shapes and text, SVG is usually ideal: it's crisp at every scale, often only a few kilobytes, editable in code, and stylable with CSS. For photographs, screenshots, and anything with fine per-pixel detail or gradients too complex to describe as shapes, SVG falls apart, you can't meaningfully vectorise a photo, and PNG's exact pixel grid is exactly what you want.
Below is a side-by-side of how the two formats behave, when each is the right tool, and a clear verdict, with the free converters to move between them.
SVG vs PNG, compared
Every dimension that actually affects the decision, at a glance.
| Dimension | SVG | PNG |
|---|---|---|
| Image type | Vector, described as shapes, lines and curves (math). | Raster, a fixed grid of individual pixels. |
| Scaling | Infinite, perfectly crisp at any size, no quality loss. | Fixed: blurs or pixelates when enlarged past its resolution. |
| Best content | Logos, icons, illustrations, line art, flat shapes and text. | Photos, screenshots, textures and fine per-pixel detail. |
| File size | Tiny for simple graphics. Can balloon for very complex artwork. | Fixed by pixel dimensions. Large for big or detailed images. |
| Editability | Editable as plain text/code. Stylable and animatable with CSS. | Edited pixel-by-pixel in a raster editor, not code-editable. |
| Transparency | Full support, plus partial fills and gradients. | Full 8-bit alpha transparency. |
| Photographs | Unsuitable, cannot represent photographic detail efficiently. | Excellent, the standard for lossless raster images. |
| Responsiveness | One file serves every screen density (Retina and beyond) crisply. | Needs multiple sizes (1x/2x/3x) to stay sharp across screens. |
Which one is right for you?
Choose SVG when
- The graphic is a logo, icon or illustration made of clean shapes and text.
- It must stay crisp at every size and on every screen density from favicon to hero.
- You want a tiny file you can edit in code, recolor with CSS, or animate.
- You need one asset that adapts to any resolution without exporting multiple sizes.
Choose PNG when
- The image is a photograph, screenshot or has fine per-pixel detail.
- The artwork is too complex to describe as vector shapes efficiently.
- You need a format that opens in every image viewer and editor by default.
- You're capturing a rendered result (a chart image, a UI snapshot) at a fixed size.
The verdict
Use SVG for logos, icons and any graphic built from shapes and text, it's smaller, infinitely scalable and editable, which makes it the modern default for interface and brand assets. Use PNG for photographs, screenshots and detailed raster imagery that can't be expressed as vectors. If you have a logo trapped in a PNG, converting it to SVG (where the shapes allow) future-proofs it. If you need a fixed-size raster of an SVG for a tool that won't render vectors, export it to PNG.
