Frequently asked questions
How much smaller is WEBP than JPG?
Typically 25–35% at matching visual quality, which is why it is worth doing for anything you serve over the web. The saving is largest on photographs and smallest on images that were already heavily compressed.
Is WEBP supported everywhere?
Every current major browser supports it, including Safari since version 14. Older email clients and some desktop software still do not, so keep a JPG fallback for anything that leaves the web.
Does converting JPG to WEBP lose quality?
It is a second lossy pass, so a little. Start from the original image rather than an already-compressed JPG where you can. If you must convert an existing JPG, staying at quality 80 or higher keeps the loss invisible in practice.
Will WEBP help my Core Web Vitals?
It helps Largest Contentful Paint, which is usually an image on a page like a hero or product shot. Smaller bytes mean the largest element paints sooner — though sizing images correctly and lazy-loading what is below the fold matter just as much.
