Convert JPG to WebP for faster pages

What you gain

• Roughly 25-35% smaller than JPG at comparable quality.
• Handles photographs and flat graphics equally well, unlike JPG.
• Supports transparency, so it can replace PNG as well.
• Supported by every current browser on desktop and mobile.

What to watch for

Some desktop applications, older operating systems and a few upload forms still reject WebP. Use it on your website and keep a JPG copy for anything you email or hand to a third party.

How much you actually save

On a typical article page with a hero image and six photographs, moving from JPG to WebP at matched quality usually removes 30-40% of total image weight. On a slow mobile connection that is often the difference between a page feeling instant and feeling sluggish.

The saving compounds with correct sizing. Resize each image to the width it is displayed at first, then convert — resizing alone typically saves more than the format change does.

Serving it safely

• Use a picture element or a content-negotiating CDN so unsupported clients still get a JPG.
• Keep the original JPG or PNG masters; re-encoding from WebP later compounds quality loss.
• Do not send WebP as an email attachment — some desktop mail clients still cannot preview it.
• Re-test your page speed after the switch so you can see what the change bought you.

Frequently asked questions

Does converting to WebP lose quality?

Lossy WebP re-encodes the image, so there is a second generation of loss on top of the JPG. At normal quality settings it is not visible, but always convert from the best original available.

Will WebP help my search rankings?

Only through speed. Faster pages perform better on page experience signals; the format itself is not a ranking factor.
