What Is PNG to WebP Conversion?
PNG is a widely used, lossless image format, common for logos, icons, screenshots, and any graphic that needs a transparent background. WebP is a newer format that generally compresses more efficiently than PNG while still supporting transparency, making it a better fit for publishing images on the web.
Converting PNG to WebP is typically done to shrink image file sizes for a website or app without giving up transparency — something converting to JPG can't do.
Why Convert PNG to WebP?
- Smaller files for the web — WebP typically produces noticeably smaller files than PNG for the same image, speeding up page loads.
- Transparency kept — unlike JPG, WebP supports transparent backgrounds, so logos and icons convert cleanly.
- Page speed scoring — tools like Lighthouse and PageSpeed Insights commonly flag large PNGs and suggest converting to a modern format like WebP.
- Good for graphics and photos alike — WebP handles both flat-color graphics and photographic images reasonably well.
PNG vs WebP
| Feature | PNG | WebP |
| Compression | Larger, lossless | Generally smaller, lossy or lossless |
| Transparency | Supported | Supported |
| Browser Support | Universal | All modern browsers |
| Typical Use | Logos, icons, screenshots | Web pages, app assets |
| Best For | Maximum compatibility with older software | Publishing on the modern web |
The size reduction from PNG to WebP depends heavily on the image — flat-color graphics and photos compress differently, so treat any specific percentage as a general expectation rather than a guarantee.
