Does PNG to WebP keep transparency?

Yes. WebP supports transparency, so any transparent areas in your PNG are preserved in the WebP file.

How much smaller is WebP than PNG?

Lossless WebP is typically 25–35% smaller than an equivalent PNG. If you allow lossy WebP, files are often a fraction of the original size with little visible difference.

PNG is a lossless format, which makes it great for crisp logos and screenshots but heavy for the web — a single full-page PNG can run to several megabytes. Converting to WebP keeps the image looking the same while making the file dramatically smaller, which is the main reason sites switch.

Why convert PNG to WebP?

Much smaller files. Lossless WebP is usually 25–35% smaller than the same PNG; with lossy WebP the saving is far larger. Lighter images mean faster pages and better Core Web Vitals.
Transparency is kept. WebP supports an alpha channel just like PNG, so logos and cut-outs stay transparent after the conversion.
Supported everywhere. Chrome, Safari, Firefox and Edge have all handled WebP for years, so you can serve it to visitors without a fallback in most cases.

When to keep the PNG

WebP is the better choice for almost anything you put on a website. Stick with PNG only when a tool in your workflow can't read WebP yet — some older desktop or print software still expects PNG. For the web, the smaller WebP wins.

How it works

Drop your PNG files above and they're re-encoded to WebP on your own device — nothing is uploaded. Adjust the quality if you want an even smaller file, then download a single image or the whole batch as a ZIP.
