Smaller pages, same pictures

Converting site images to WebP is one of the few free performance wins left: 25–35% off every image at equal visual quality, supported by every current browser. The catch list is short but real — some desktop apps, older devices and print workflows still balk.

Property	JPG	WebP
File size	Baseline	25–35% smaller
Current browsers	Universal	Universal
Older software	Universal	Patchy
Quality change on convert	—	Existing artefacts carry over
Best role	Master copies	Web delivery

Typical jobs people use this for

Cutting a blog's page weight without touching layouts
Speeding up a shop where product photos dominate load time
Reducing bandwidth on an image-heavy landing page

When this is the wrong tool

Keep the JPG originals as masters and treat WebP as an output format — requirements change, and you'll want to re-export. Don't bother converting images that never travel over the web.

Frequently Asked Questions

How much smaller will the file be?

Typically 25–35% smaller than the equivalent JPG at the same visual quality. On an image-heavy page that adds up to a meaningful difference in load time.

Will WebP display everywhere?

In browsers, effectively yes — Chrome, Firefox, Safari and Edge have all supported it for years. Outside the browser it is patchier: some desktop applications, older phones and print workflows still reject it, so it is a web-delivery format rather than a universal one.

Does converting improve the image?

No. Converting from JPG carries over the artefacts already present, then re-encodes them more efficiently. You get a smaller file of the same visual quality, not a better image.

Should I keep the JPG originals?

Yes. Keep originals as your master copies and treat WebP as an output format for the web. That way you can re-export later if requirements change.

Is anything transmitted while converting?

No. Conversion runs in your browser.
