Before you start

Choose WebP when the destination supports it and the format fits your workflow. Keep the source image so you can create another format later if compatibility requirements change.

What is WebP?

WebP is an image format designed for efficient delivery. It supports both lossy and lossless compression and can represent transparency, making it flexible for web assets.

WebP versus JPG

Photographs can often become smaller as WebP, but the result depends on the source and quality. JPG remains useful where compatibility with older software or an existing workflow matters.

WebP versus PNG

WebP can be useful for graphics and transparent assets as well as photographs. Compare the actual output rather than assuming one format is always smaller.

Quality settings

A higher quality setting generally retains more visual information at the cost of bytes. A lower setting can be useful when file size matters, but inspect fine text and high-frequency textures.

A practical workflow

Create a WebP copy, compare its size and appearance with the source, check your destination's compatibility and keep the original for future exports.

Frequently asked questions

Is WebP always smaller?

No. Results depend on the image and settings.

Can WebP have transparency?

Yes.

Should every website use WebP?

It can be a useful option, but the right format depends on the site's browser, CMS and delivery requirements.

Keep your original file.

Image processing creates a derivative. Retaining the original makes it easier to create another size, crop or format later.
