Verdict: SVG wins for logos, icons, and diagrams — one tiny file that stays razor-sharp at every size. PNG wins for anything photographic, which vectors cannot represent. Icons and logos go SVG; photos, screenshots, and textures go PNG.
| Criterion | SVG | PNG |
|---|---|---|
| Image type | Vector — mathematical shapes | Raster — fixed grid of pixels |
| Scaling | Infinite with zero quality loss | Pixelates and blurs when enlarged |
| File size | Tiny for logos and icons | Grows with dimensions and detail |
| Photographs | Cannot represent photos | The right choice for photos |
| Editing | Text-editable code, styleable with CSS | Needs a pixel editor |
| Animation | Animatable with CSS and JavaScript | Frame-based animation only |
| Best for | Logos, icons, diagrams, illustrations | Photos, screenshots, complex imagery |
Every tool below runs entirely in your browser — your files never leave your device.
Tracing a photo into vectors produces huge files that still look worse than the PNG. SVG is for shapes, not pixels — keep photos as PNG (or JPG/WebP).
One SVG replaces a whole set of PNG sizes (1x, 2x, 3x), stays sharp on retina and 4K screens, and can be recolored with a line of CSS.
Mostly no — many email clients block or ignore SVG. Convert to PNG at 2x size for newsletters and email signatures.
For simple graphics, dramatically so. For complex illustrations with thousands of paths, an optimized PNG can win — compare both before deciding.
