Why convert PNG to WEBP?
PNG files are excellent for quality but can be very large. WEBP achieves similar quality at much smaller file sizes — typically 25–35% smaller than equivalent PNG files. Converting PNG to WEBP is essential for fast-loading websites and modern web apps. All modern browsers support WEBP natively, and the smaller file sizes directly translate to faster page loads and lower bandwidth costs.
