- • Lossy compression artifacts
- • Poor for graphics/text
- • Quality loss on re-save
- • Limited color depth
PNG Format Analysis
PNG (Portable Network Graphics)
PNG is designed for graphics and images that require transparency or lossless compression.
- Compression: Lossless compression, 5:1 to 10:1 ratio
- File Size: Medium to large

| Feature | JPEG | PNG | WebP |
|---|---|---|---|
| Compression Type | Lossy | Lossless | Both |
| File Size | Small | Large | Smallest |
| Transparency | No | Yes | Yes |
| Browser Support | 100% | 100% | 95%+ |
| Best For | Photos | Graphics | Both |
When to Use Each Format
Use JPEG When:
- • Sharing photographs online
- • Maximum browser compatibility needed
- • File size is critical
- • No transparency required
- • Legacy system compatibility
Use PNG When:
- • Graphics with transparency
- • Screenshots with text
- • Logos and icons
- • Lossless quality required
- • Maximum compatibility needed
Use WebP When:
- • Modern web applications
- • Performance is critical
- • Both photos and graphics
- • Transparency needed
- • Progressive enhancement strategy
Implementation Strategy
Progressive Enhancement with Picture Element
<!-- Modern approach with fallbacks -->
<picture>
<source srcset="image.webp" type="image/webp">
<source srcset="image.jpg" type="image/jpeg">
<img src="image.jpg" alt="Description" width="800" height="600">
</picture>
<!-- CSS approach -->
<style>
.image {
background-image: url('image.webp');
}
@supports not (background-image: url('image.webp')) {
.image {
background-image: url('image.jpg');
}
}
