Why convert JPEG to WEBP?

Introduced in 1992 by JPEG Committee, JPEG was great for its time. But WEBP (created in 2010 by Google) offers lossy/lossless compression and 24-bit – a massive leap forward. Modern web formats like WEBP offer superior compression compared to JPEG. Switching to WEBP can improve your Core Web Vitals and reduce bandwidth costs by 30–50%. convert.dynamic_reason_closing.closing_13
