PNG vs JPG vs SVG: Which Format Should You Use?
The three most common image formats serve very different purposes. Here's how to choose the right one every time.
Use SVG For:
- Logos and brand marks
- Icons and UI elements
- Illustrations and diagrams
- Graphics that need to scale
Use PNG For:
- Graphics with transparency
- Screenshots
- Graphics requiring pixel-perfect accuracy
- Images with text overlays
Use JPG For:
- Photographs
- Complex images with gradients
- Social media images
- When file size matters most
PNG vs JPG vs SVG: At a Glance
| Feature | SVG | PNG | JPG |

| Transparency | Yes | Yes | No |
| Scalability | Infinite, lossless | Fixed resolution | Fixed resolution |
| File Size (logo) | ~2-10 KB | ~50-500 KB | ~20-200 KB |
| File Size (photo) | Huge / impractical | ~500 KB - 5 MB | ~50-500 KB |
| Editable | Yes (code + software) | Limited | Destructive only |
| Animation | CSS/JS animations | APNG only | No |
| Best For | Logos, icons, graphics | Screenshots, transparency | Photos, gradients |
| Browser Support | All modern | Universal | Universal |
When to Use Each Format
SVG — Scales perfectly in header, footer, favicon. ~3KB file, crisp on all screens.
PNG — Needs multiple sizes (16px, 32px, 200px). Larger files, blurry when scaled up.
JPG — No transparency support. Compression artifacts visible on sharp edges.
SVG — Cannot represent photographic detail. Would create massive, impractical files.
PNG — Good if you need transparency (product on white bg). Large file size though.
JPG — Best choice. Small file, great quality at 80-85% compression. No transparency needed.
SVG — Perfect. Tiny files, crisp at any DPI, CSS-styleable (hover colors, dark mode).
PNG — OK fallback. Need @1x, @2x, @3x versions for retina displays.
JPG — Poor choice. No transparency, compression ruins sharp icon edges.
SVG — Social platforms don't accept SVG uploads.
PNG — Best for graphics with text. Lossless quality preservation.
JPG — Best for photo-based posts. Smaller file = faster upload.
For Websites: Performance Comparison
Smallest files for graphics. Can be inlined in HTML (zero HTTP requests). CSS-animatable. Crisp on all screen densities without @2x/@3x variants.
Best for: logos, icons, illustrations
Lossless quality for screenshots and overlays. Supports transparency. Larger files than JPG for photos. Consider WebP as a modern alternative.
Best for: screenshots, overlays, text graphics
Best compression for photos. 80-85% quality is visually identical to lossless. No transparency. Avoid for text or sharp edges (artifacts).
Best for: photos, hero images, backgrounds
Frequently Asked Questions
Use JPG for photographs and complex images (smaller files). Use PNG when you need transparency or for screenshots/graphics with text. For logos and icons, skip both and use SVG.
For logos, icons, and simple graphics - yes. SVG is smaller, scales infinitely, and is editable. But SVG cannot represent photographs - that's where PNG and JPG excel. Each format has its ideal use case.
Yes! PNG/JPG to SVG is best for logos and graphics (our AI handles this). SVG to PNG/JPG is straightforward export. JPG to PNG preserves quality but increases file size. PNG to JPG reduces size but loses transparency.
WebP and AVIF are modern raster formats that offer better compression than PNG and JPG. They're great for web photos but don't replace SVG for vector graphics. Use WebP/AVIF for photos, SVG for graphics.
