Compare PNG and JPEG image formats for web use. Side-by-side comparison of compression, quality, transparency, and best use cases for each format.
| Aspect | PNG | JPEG | Winner |
|---|---|---|---|
| Compression | Lossless — no quality loss | Lossy — smaller files with some quality loss | Draw |
| File size | Larger files (2-5x JPEG) | Compact files, adjustable quality | JPEG |
| Transparency | Full alpha channel support | Not supported | PNG |
| Photographs | Large file sizes | Excellent quality-to-size ratio | JPEG |
| Graphics and text | Sharp and artifact-free | Blurring and artifacts around text | PNG |
Rarely. PNG uses lossless compression and is typically 2-5 times larger than JPEG at equivalent quality. PNG excels for images with large areas of solid color.
JPEG generally wins for photographs. Consider WebP as a modern alternative that combines PNG's transparency with JPEG's compression efficiency.
