What is JPG?

JPG (JPEG) is the world's most popular image format, published in 1992. It uses lossy DCT-based compression to create compact image files. JPG is universally supported but uses older compression technology that produces larger files compared to modern formats.

For websites, JPG images are often the largest assets on the page, directly impacting load times and Core Web Vitals scores.

What is WebP?

WebP is Google's modern image format (2010), based on VP8/VP9 video codecs. It supports both lossy and lossless compression, transparency, and animation. Lossy WebP produces files 25–34% smaller than JPEG at equivalent visual quality.

WebP has 97%+ browser support in 2026 (Chrome, Firefox, Safari, Edge). Google explicitly recommends WebP for web images to improve page speed and Core Web Vitals.

Why Convert JPG to WebP?

Smaller file sizes

WebP produces files 25–34% smaller than JPEG at equivalent visual quality. For a website with 50 images, this can reduce total image payload by hundreds of kilobytes.

Faster page loads

Smaller images load faster, directly improving user experience and reducing bounce rates. Every kilobyte saved matters on mobile connections.

Better SEO

Google's Core Web Vitals include Largest Contentful Paint (LCP), which measures how fast the largest content element loads. WebP images directly improve LCP scores and thus search rankings.

Modern standard

Google explicitly recommends WebP in PageSpeed Insights. With 97%+ browser support, there is no practical reason to keep serving JPG to web visitors.

Frequently Asked Questions

For website images, yes. WebP saves 25–34% on file sizes with equivalent quality. Use the <picture> element with JPG fallback for the ~3% of browsers that do not support WebP.
Yes. WebP supports full alpha channel transparency in both lossy and lossless modes, making it a replacement for both JPG (photographs) and PNG (graphics with transparency).
No. At equivalent settings, WebP produces equal or better quality than JPEG. At quality 90, WebP output is visually indistinguishable from the JPEG source.
No. Email clients have very poor WebP support. Use JPEG for photographs and GIF for animation in emails. WebP is best for websites where you control the display environment.
Use the HTML <picture> element with WebP source and JPG fallback: <picture><source srcset='image.webp' type='image/webp'><img src='image.jpg'></picture>.
