FAQ
Frequently asked questions
Do all browsers support WebP?
Yes, every modern browser displays WebP. Some older desktop apps and upload forms may not, so keep the PNG as a backup.
Is WebP lossless?
WebP can be either; this tool uses lossy WebP with a quality setting, which gives the biggest savings with little visible change.
Why is my browser missing the WebP option?
A few older Safari versions can't create WebP files. Update your browser or try Chrome, Edge or Firefox.
Will it help my site's SEO?
Smaller images load faster, which improves Core Web Vitals — one of the signals search engines use.
