Frequently Asked Questions

What is srcset?

srcset is an HTML attribute that provides multiple image sources at different sizes. The browser automatically picks the best one for the device's screen size and resolution.

How many sizes should I generate?

3-5 sizes is typical: 320px (mobile), 768px (tablet), 1280px (desktop), 1920px (large screens). Adjust based on your layout.

Does this improve page speed?

Yes, significantly. Mobile users download smaller images instead of the full-size version, reducing bandwidth and load time.
