Why convert PNG to WebP
WebP was built for the web and usually produces much smaller files than PNG at a similar visual quality, which means faster page loads and lower bandwidth. It also supports transparency, so it is a strong replacement for transparent PNG assets.
This is a common step when optimizing a website or app, where large PNG icons, illustrations, and screenshots slow the page down more than they need to.
- You are optimizing images for a website or app
- A large transparent PNG needs to be lighter
- You want modern format support with smaller files
Balancing size and quality
WebP supports both lossy and lossless modes. The quality slider controls the trade-off, letting you shrink the file while keeping it visually clean.
The PNG is re-encoded as WebP directly in your browser, so the process stays fast and private, and transparency is preserved.
