Why Compress PNGs?
PNG is a lossless format — every pixel is preserved exactly. But that precision comes at a cost: PNG files can be significantly larger than JPG or WebP equivalents. Compressing PNGs by re-encoding them at a controlled quality level shrinks file sizes for web delivery while keeping the visual quality high. Smaller images mean faster page loads and better Core Web Vitals scores.
Quality Guide
| Quality | Best for | Typical size reduction |
|---|---|---|
| 90–100% | Print, archival, near-lossless | 10–30% |
| 75–89% | Web images, product photos | 30–60% |
| 50–74% | Thumbnails, social previews | 50–75% |
| Below 50% | Low-bandwidth delivery | 70–85% |
PNG vs WebP Output
Choosing WebP as the output format typically produces files 25–35% smaller than compressed PNG at equivalent visual quality. WebP is supported by all modern browsers. Use PNG output when you need maximum compatibility with older software.
