SVG and PNG can both display transparent graphics, but they store completely different kinds of information. SVG describes shapes and paths. PNG stores a fixed grid of pixels.
SVG stays sharp at different sizes
A true vector logo can scale from a small navigation icon to a large display without becoming blurry. This makes SVG useful for responsive website branding and interface icons.
SVG is not a magic way to improve a low-resolution photograph. Converting a raster photo into an SVG wrapper does not recreate vector detail.
PNG is predictable for raster graphics
PNG is a good choice for screenshots, textured artwork and graphics that already exist as pixels. It supports transparency and is widely compatible.
A PNG logo needs enough pixel dimensions for its largest use. Scaling beyond the original size can reveal softness or jagged edges.
File size depends on the artwork
Simple icons and logos can be extremely compact as SVG. Very complex vectors with thousands of paths may be larger and slower than a well-sized PNG.
Test the real asset rather than assuming one format is always smaller.
Practical recommendation
- Use SVG for clean vector logos and icons.
- Use PNG for screenshots and pixel-based artwork with transparency.
- Provide explicit width and height on website images to reduce layout movement.
- Only use SVG files from trusted sources because SVG can contain active content.
