How to convert PNG to WebP

What is PNG?
PNG is a lossless image format that preserves every pixel exactly and supports a full alpha-transparency channel. It is the standard choice for logos, icons, screenshots and any graphic with sharp edges, flat colour or transparent areas.
What is WebP?
WebP is a modern image format from Google that supports both lossy and lossless compression plus transparency and animation. It typically produces files 25–35% smaller than JPG or PNG at the same visual quality, which is why it is popular for fast-loading websites.

Why convert PNG to WebP?
Converting PNG to WebP gives you a file that is better suited to web images where page speed matters and replacing jpg and png, and that opens it up to far more apps, devices and websites.
What WebP gives you: smaller than JPG/PNG at equal quality, supports transparency and animation and lossy and lossless modes.
Where PNG falls short: much larger than JPG for photographs, no animation and not ideal for print colour profiles. Converting keeps your content while moving to a format that matches where the file is going.

- You can convert several files in one go — add as many PNG files as you like and download them together.
