Converted Images
WebP is a modern image format developed by Google that delivers 25-35% smaller file sizes compared to JPG at equivalent visual quality. Converting your JPG images to WebP is one of the most impactful optimizations you can make for website performance, directly improving Core Web Vitals scores and reducing bandwidth costs.
Why Convert JPG to WebP?
The primary advantage of WebP over JPG is superior compression efficiency. WebP uses more advanced compression algorithms (based on VP8 video codec technology) that achieve the same visual quality at significantly smaller file sizes. For a typical photograph, a 200KB JPG file can be reduced to 130-150KB as WebP without any perceptible quality difference.
WebP also supports transparency (alpha channel) and animation, features that JPG lacks entirely. This makes WebP a versatile single format that can replace JPG for photographs, PNG for transparent graphics, and even GIF for simple animations. For web developers managing image assets, this simplification is valuable.
Google's PageSpeed Insights specifically recommends serving images in WebP format. Since Google created WebP, its tools are naturally aligned to favor it. Websites that serve images in WebP consistently score higher on performance audits, which correlates with better search rankings and improved user experience metrics.
Browser Support for WebP
As of 2024-2025, WebP is supported by over 97% of web browsers globally, including Chrome, Firefox, Edge, Safari (since version 14), Opera, and all major mobile browsers. The only notable holdouts are very old browser versions that represent a negligible share of web traffic. For practical purposes, WebP can be considered universally supported on the modern web.
For the rare cases where you need backward compatibility with very old systems, the HTML <picture> element allows you to serve WebP to supporting browsers and fall back to JPG for others. Most modern CMS platforms and CDNs handle this automatically.
Quality Settings for WebP
Our converter includes a quality slider that controls the WebP compression level. For most use cases, 80-85% quality offers the best balance of file size reduction and visual fidelity. At this setting, the difference from the original JPG is imperceptible to most viewers, while file sizes are typically 30% smaller. Going below 70% starts to introduce visible artifacts, similar to aggressive JPG compression.
