PNG vs SVG: keep the vector master and export pixels on purpose.
PNG is a reliable raster delivery format. SVG is a scalable document format. A practical logo workflow usually needs both, but not for the same job.
Use SVG as the approved logo master. Export PNG for fixed-size delivery.
Choose SVG for websites, editing and any surface that may change size. Choose PNG when a platform requires pixels, when dimensions are known or when the artwork depends on raster effects that should remain raster.
The useful differences are structural.
PNG stores a rectangular array of pixels and can include alpha transparency. SVG describes graphical elements such as paths and can also embed raster images, so the extension alone does not prove that a logo is genuinely vector.
| Question | PNG | SVG |
|---|---|---|
| Image model | A fixed grid of pixels | Shapes, paths and fills |
| Scaling | Larger display reveals pixels | Geometry redraws at the requested size |
| Transparency | Supported with an alpha channel | Supported by vector shapes and opacity |
| Editing | Pixel-level image editing | Individual shapes and colors can be edited |
| Best role | Delivery at known dimensions | Master artwork and responsive interfaces |
| Common risk | Too few source pixels | Unnecessary complexity or embedded raster content |
More display pixels do not create more source detail.
A browser can enlarge either format. The raster still has a fixed sampling grid; the vector renderer recalculates the geometry for the new display size.
Do not force one format to handle every surface.
Choose SVG
- Website headers and responsive layouts
- Editing colors or individual logo shapes
- Generating multiple raster sizes from one master
- Simple marks, icons, badges and wordmarks
Choose PNG
- Platforms that explicitly require raster uploads
- Known dimensions such as a social profile image
- Pixel-based textures, photography or complex effects
- A reviewed derivative generated from the SVG master
Three assumptions that produce bad handoffs.
“SVG is always smaller.”
Simple geometry can be compact. Thousands of paths, embedded images or verbose exports can be larger than a suitable PNG.
“Transparent means vector.”
PNG supports an alpha channel. Transparency says nothing about whether the artwork is built from pixels or paths.
“Saving as SVG vectorizes it.”
An SVG may contain an image element that points to or embeds the same raster. Inspect the content, not only the extension.
