Convert PNG to WebP Online
Need to turn a PNG file into WebP? PNG (Portable Network Graphics) is a lossless format built for graphics rather than photos. It keeps every pixel exactly and supports a full alpha channel, so it is the go-to for logos, icons, screenshots and anything with transparency or crisp edges. WebP is a modern format from Google that compresses far better than JPG or PNG at the same quality. It supports both lossy and lossless modes, transparency and animation, which makes it the format of choice for fast-loading websites. Converting from PNG to WebP bridges the two: you keep the picture, but in a format that fits where you are taking it.

What to expect converting PNG to WebP
WebP is typically 25-45% smaller than the same PNG, often more for photographic content.
Lossless WebP keeps every pixel; lossy WebP shrinks further with negligible visible loss.
Use it to speed up web pages and improve Core Web Vitals while keeping transparency.
Avoid it for assets that must open in older or non-web software.
