Web developers know that WebP is much smaller than PNG or JPG at the same quality, so pages load faster. Converting PNG to WebP keeps the quality while significantly shrinking file size — a common technique for web performance optimization.
This guide covers how to convert PNG to WebP online and when it makes sense.
Why convert to WebP
- Smaller files: WebP is typically 30%+ smaller than PNG at similar quality
- Faster loading: smaller files mean noticeably faster page loads
- Transparency preserved: WebP supports alpha, so PNG transparency carries over
- Browser support: all major browsers now support WebP
If your images are mainly for the web, converting to WebP speeds up loading significantly.
