What is PNG to WebP Converter?
A PNG to WebP converter is a tool that transforms PNG image files into WebP format — Google's modern image format designed for the web. PNG produces large, lossless files perfect for editing and design work, but they are often oversized for web delivery. This converter takes those PNG files and re-encodes them as WebP, reducing file size by 25–35% while preserving full transparency and maintaining excellent visual quality.
Unlike traditional converters that require software installation or file uploads, this tool runs entirely in your browser using the Canvas API. Your images never leave your device — conversion is instant, private, and free.
About PNG Format
PNG (Portable Network Graphics) uses lossless compression and supports full alpha channel transparency. It is widely compatible across all software but produces larger files — best for editing, logos, and graphics requiring perfect quality.
Why Convert to WebP?
WebP delivers 25-35% smaller file sizes compared to PNG while preserving transparency. Smaller images mean faster page loads, better Core Web Vitals scores, and reduced bandwidth costs — all critical for modern web performance.
