SVG vs PNG: Which Should You Use?
SVG and PNG can both show logos and icons with transparent backgrounds, but they work differently: SVG stores shapes (vector), PNG stores pixels (raster).
SVG vs PNG
Short answer
Use SVG for logos, icons and illustrations on websites: sharp at any size and tiny. Use PNG for screenshots, photos, and anywhere SVG isn't accepted.
SVG vs PNG at a glance
| Property | SVG | PNG |
|---|---|---|
| Compression | Vector (shapes, not pixels) | Lossless (exact pixels, larger files) |
| Transparency | Yes | Yes |
| Animation | Yes | No |
| Opens in | All browsers | All browsers and devices |
| Best for | Logos, icons and illustrations that must stay sharp at any size | Logos, screenshots, graphics, images with text or transparency |
| Scaling | Sharp at any size | Blurs when enlarged |
| Editable | Shapes, colors and text in code or design apps | Pixel editing only |
Use SVG for
- Logos and icons on websites
- Illustrations and diagrams
- Cutting machines (Cricut) and laser engravers
- Anything shown at many sizes
Use PNG for
- Screenshots and photos
- Social media and messaging
- Documents and slides that don't take SVG
- Complex, detailed artwork
Key differences
Vector vs raster
An SVG describes shapes mathematically, so it stays sharp from a favicon to a billboard. A PNG has a fixed number of pixels.
File size
Simple SVG logos are often just a few KB. Complex artwork or photos are far larger as SVG than as PNG.
Compatibility
Browsers and design tools support SVG, but many social networks, email clients and upload forms only accept PNG or JPG.
SVG
What is an SVG file?
Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. Developed by the World Wide Web Consortium (W3C) since 1999, SVG is an open standard that describes images using text-based XML markup, allowing them to be indexed, scripted, and compressed. Unlike raster formats, SVG images are resolution-independent, relying on mathematical paths (vectors) rather than pixels, making them essential for responsive web design and high-DPI displays.
How to open an SVG file
SVG files are natively supported by all modern web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari, which render the XML data directly. for editing, users require vector graphics software such as Adobe Illustrator, Inkscape, or CorelDRAW. Plain text editors like VS Code or Notepad++ can also open SVG files to view and modify the underlying XML source code.

PNG
What is a PNG file?
Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression, created as a patent-free replacement for the Graphics Interchange Format (GIF). Standardized as ISO/IEC 15948:2004, PNG utilizes the DEFLATE compression algorithm (a combination of LZ77 and Huffman coding) and supports palette-based images, grayscale, and full-color non-palette-based RGB/RGBA images. A defining feature is its alpha channel support, allowing for variable transparency levels, unlike the binary transparency of GIF. It does not support animation but offers gamma correction and interlacing via the Adam7 algorithm.
How to open a PNG file
PNG files possess near-universal compatibility across all major operating systems (Windows, macOS, Linux, Android, iOS) and web browsers (Chrome, Firefox, Safari) without requiring additional software. Default image viewers such as Microsoft Photos, Apple Preview, and virtually all graphics editing software including GIMP, Adobe Photoshop, and Paint.NET natively handle the format.
