Image Format Comparison

SVG vs PNG: Vector vs Raster for Icons and Logos

SVG and PNG solve different problems. SVG is a vector format — it describes shapes with mathematical paths, so it scales perfectly from a tiny favicon to a massive banner without any blurring. PNG is a raster format — it stores a fixed grid of pixels, which means it can only look its best at one specific size. For anything you design (logos, icons, charts), SVG is almost always the right choice; for anything you photograph or screenshot, PNG is the practical answer.

Quick Verdict

Use SVG when…

Use SVG for logos, icons, illustrations, and any graphic that must look sharp at every size — from a 16px favicon to a 4K display or printed billboard.

Use PNG when…

Use PNG when the image is a photo or complex raster graphic, when you need maximum software compatibility (older apps, Word, email clients), or when SVG's code-based nature is impractical.

SVG vs PNG: Feature Comparison

Feature	SVG	PNG
Format type	Vector — defined by math/paths	Raster — defined by pixels
Scalability	Infinite — crisp at any resolution	Fixed — blurs when scaled up
File size for icons	Very small (1–5 KB for simple icons)	Larger (10–100 KB for equivalent quality at high-res)
Transparency	Supported natively	Full alpha channel transparency
Editability	Open in any text editor; paths are code	Requires image editor to modify
Browser support	All modern browsers; limited in old email clients	Universal including legacy browsers and email

Frequently asked questions

Can SVG display photos like PNG can?

SVG can embed raster images inside it, but it's not designed for photographic content. For photos, use PNG or JPG directly.

Does SVG work in email newsletters?

Most email clients (especially Outlook) do not render SVG. For email, export a PNG version. For the web, use SVG.

Is SVG safe to use on websites?

Yes, when SVG is served as a static file. Be cautious embedding untrusted SVG inline — SVG supports JavaScript, so inline SVGs from unknown sources could be a security risk.

Which is better for Retina/HiDPI displays?

SVG looks perfect on every display automatically. PNG needs a 2× or 3× version exported manually; using CSS background-size or srcset helps, but SVG is simply the easier solution.
