Practical guidance

When to use JPG to WebP

Best for

Preparing JPEG photographs for websites that accept WebP.

What you get

A static WebP image at the original width and height, using the quality you select.

Useful tip

Start with the best JPG available. Converting an already compressed photo cannot recover missing detail.

Prepare a photograph for web delivery

If a photo is much wider than its intended display, resize it first. Then compare WebP quality settings using the original as a reference. Look at faces, foliage and gradients rather than choosing the smallest file automatically.
