PNG to WebP Converter - Convert PNG to WebP Online Free

How to convert PNG to WEBP

Add your PNG files. Drop up to 50 PNG images into the box, or browse for them. They never leave your device.
Lossy or lossless. Quality 85 is the default and looks like the original. Lossless keeps every pixel - ideal for logos and screenshots.
Adjust if you like. Resize, keep or fill transparency, or rename. Every option starts closed and shows its value.
Convert and download. Press Convert to WebP. One or two files download directly, more than two come as a ZIP.

Using it on a website? Put the WebP in a picture element with the PNG as fallback for very old browsers.

WebP keeps transparency like PNG but is much smaller.

Lossless WebP is usually 25% smaller than PNG; lossy WebP at quality 85 is often 70-80% smaller and looks the same.

Every modern browser, WordPress and most apps open it.
