Why Convert PNG to WebP?
PNG files with transparency are often very large. WebP handles transparency just like PNG but at a fraction of the file size, making it ideal for logos, icons, and product images on websites.
Lossy vs Lossless
The quality slider controls lossy compression. For maximum quality with transparency, set quality to 100 for lossless output. For smaller files, 85 to 90 is usually visually identical.
