Why convert JPG to WebP?

WebP is a modern image format that delivers the same visual quality as JPG at a noticeably smaller size — often 25–35% less. Smaller images mean faster pages and lower bandwidth, which is why WebP is now the default for performance-focused websites.

How it works in your browser

Each JPG is drawn to a canvas and re-encoded as WebP on your device — nothing is uploaded. You can convert many images in one batch and download them together.

When to use WebP

Use WebP for images on websites and web apps where speed matters, and where you control which browsers and tools will open them. All modern browsers support WebP; some older software and a few platforms still do not.

JPG vs WebP

JPG is universally supported and a safe default for sharing anywhere. WebP gives smaller files at the same quality but is not accepted everywhere. Convert to WebP for the web, and keep or convert back to JPG when you need maximum compatibility.
