SVG vs PNG for Logos: Which Format Should You Use?
Your logo appears everywhere: website headers, email signatures, social media profiles, business cards, and app icons. Each context has different requirements for resolution, size, and format support. Choosing between SVG and PNG for your logo affects how it looks across all these platforms.
SVG is the modern standard for web logos. PNG remains necessary for platforms that do not support SVG. Here is how to decide which to use where.
SVG vs PNG for Logos
| Context | SVG | PNG |
|---|---|---|
| Website header | Ideal (sharp at any size) | Acceptable (provide 2x) |
| Retina displays | Perfect automatically | Needs @2x and @3x versions |
| Email signatures | Not supported in most clients | Required (the safe choice) |
| Social media profile | Not accepted | Required format |
| Favicon | Supported (browser tab) | Required (ICO/PNG fallback) |
| CSS color changes | Yes (inline SVG) | No (fixed colors) |
| Dark mode support | Automatic via CSS | Separate dark logo needed |
| Print (business cards) | Preferred (vector output) | Acceptable at 300+ DPI |
| File size | 1-10KB typical | 10-100KB (depends on resolution) |
| Editing tool output | Illustrator, Figma, Sketch | Any image editor |
Why SVG Is Ideal for Web Logos
A logo is typically a simple geometric design: text, shapes, and clean lines. This is exactly the type of content that SVG handles best. The SVG file is tiny (often under 5KB), scales perfectly to any screen size and pixel density, and can be styled with CSS for color themes, dark mode, and hover effects.
On a modern website, an SVG logo renders crisply whether viewed on a 1x standard display, a 2x retina MacBook, or a 3x smartphone screen. A single file replaces the multiple PNG resolutions that would otherwise be needed.
CSS Control: SVG's Unique Power
Inline SVG logos can be styled with CSS. This enables powerful features that PNG cannot match. A logo can change color on hover. It can adapt to dark mode by referencing CSS custom properties. Different sections of the logo can be styled independently.
A common pattern is to define logo colors as CSS custom properties and reference them in the SVG. When the page switches to dark mode, the CSS properties update and the logo adapts automatically. With PNG, you would need separate light and dark versions of the logo.
When PNG Logos Are Still Needed
Despite SVG's advantages, PNG logos remain necessary for several contexts. Email clients (Outlook, Gmail, Apple Mail) have inconsistent or no SVG support. Social media platforms require raster images for profile photos and page logos. App stores require PNG or JPEG for app icons. Some CMS platforms and third-party integrations expect PNG.
The practical recommendation is to maintain both formats. Keep the master logo as SVG for web use and generate PNG versions at required sizes for platforms that need raster formats.
Retina and High-DPI Considerations
With PNG logos, you need multiple resolutions for different display densities. A 200x50 logo for 1x displays needs a 400x100 version for 2x retina and a 600x150 version for 3x. Managing these multiple versions adds complexity to your asset pipeline.
SVG eliminates this entirely. One SVG file at any declared size renders at the native resolution of whatever display it appears on. For teams managing brand assets across many platforms and devices, this simplification is significant.
Logo Design Considerations
Not all logos work equally well as SVG. Logos designed as clean vector graphics (geometric shapes, text, flat colors) translate perfectly to SVG. Logos with photographic elements, complex gradients, textures, or effects like drop shadows may produce larger SVG files or require raster fallbacks for accurate rendering.
If your logo includes a photograph, embossing, or complex texture effects, you may need a simplified vector version for web SVG use alongside a full-detail PNG version for contexts where the effects matter.
Frequently Asked Questions
Should I use SVG or PNG for my website logo?
SVG for the website itself. It is smaller, scales perfectly, and supports CSS styling. Provide PNG versions for email, social media, and other platforms that require raster images.
What size PNG should I export my logo at?
Export at 2x your maximum display size. If your logo displays at 200x50 on desktop, export at 400x100 minimum. For very high-DPI contexts, 3x (600x150) is safer. Always keep the SVG or vector source for re-exporting at any size later.
Can I make my logo change colors with SVG?
Yes. Inline SVG logos can reference CSS custom properties for fill colors. When those properties change (dark mode, themes, hover states), the logo colors update automatically. This is one of SVG's most powerful features for brand assets.
