Overview
This guide compares PNG and SVG across the most important criteria to help you choose the right format for your needs.
SVG is vector and scales infinitely; PNG is raster and best for complex images.
Head-to-Head Comparison
Scalability
PNG: PNG becomes blurry when scaled beyond its original resolution.
SVG: SVG scales to any size perfectly with no quality loss.
Winner: SVG
File Size
PNG: PNG is larger for simple graphics but similar to SVG for complex images.
SVG: SVG is tiny for simple graphics (logos, icons) but large for complex illustrations.
Winner: Tie
Use Case
PNG: PNG is best for photographs and complex images with many colors.
SVG: SVG is best for logos, icons, illustrations, and anything that needs to scale.
Winner: Tie
Editability
PNG: PNG pixels cannot be individually edited without image editors.
SVG: SVG paths are easily edited with text editors or vector tools.
Winner: SVG
Web Support
PNG: PNG is supported universally by every browser.
SVG: SVG is supported by all modern browsers.
Winner: Tie
How PNG and SVG Differ Technically
The core distinction is raster versus vector. PNG stores an explicit grid of pixels, compressed losslessly with DEFLATE and prediction filters, so the file describes exact color values at a fixed resolution.[1][2] SVG instead describes an image as XML instructions, paths, shapes, text, and gradients, that a renderer draws on demand.[3] Because SVG is a mathematical description rather than a pixel array, it has no inherent resolution.
Scaling and Fidelity
An SVG can be scaled to any size and stays perfectly sharp, since shapes are recomputed at the target resolution.[4] A PNG, by contrast, becomes blurry or blocky when enlarged beyond its native pixel dimensions. However, SVG is unsuited to photographs: representing millions of subtly varying pixels as vector primitives is impractical, whereas PNG handles complex per-pixel detail naturally.[1]
When Each Format Wins
SVG is ideal for logos, icons, charts, and line art that must scale across screen sizes, and because it is text-based it can be styled with CSS, animated, and searched.[3] PNG wins for screenshots, detailed graphics, and any raster artwork needing lossless pixels and transparency.[2]

Should I use SVG or PNG for my logo?
Use SVG for logos - they scale perfectly and are tiny in file size. Use PNG when SVG is not supported.
Can I use SVG on websites?
Yes, SVG is fully supported by all modern browsers and is the recommended format for icons and logos on the web.
Is SVG better than PNG for icons?
Yes, SVG icons are resolution-independent, look perfect on any screen density, and are usually smaller in file size.
Can I convert PNG to SVG?
Auto-tracing converts PNG to SVG but results vary. Complex photos do not convert well. Simple logos trace well.
Does email support SVG?
No, most email clients do not support SVG. Use PNG for email images.
