About FreeDigitalToolkit →Frequently Asked Questions
What is WebP?
WebP is a modern image format developed by Google that provides superior compression. WebP images are typically 25-35% smaller than JPG at similar quality.
Is WebP supported in all browsers?
WebP is supported in Chrome, Firefox, Edge, Safari 14+, and all modern browsers. It's safe to use for most websites.
How much smaller will my images be?
Typically 25-50% smaller than JPG at equivalent quality. The exact savings depend on image content — photos with lots of detail compress less than simple images.
What quality setting should I use for WebP?
80-85% produces WebP files that look identical to the original JPG at typical screen sizes. WebP handles compression artifacts differently than JPG, so 80% WebP often looks better than 80% JPG.
Should I use WebP for all website images?
For modern websites, yes. Use a <picture> element with WebP as primary and JPG as fallback for the rare user on very old browsers. Most CDNs also support automatic WebP serving.
