Compress Images for Web

WebP is the recommended format for web — it is 25–35% smaller than JPEG at the same quality and is supported by all modern browsers. AVIF is even smaller but encoding support is still limited. Use JPEG only as a fallback for older browsers.

1920px max width covers full-HD screens. For hero images where the browser stretches the image, 2400–2560px is safer. For thumbnails and card images, 800px or less is usually sufficient.

For image-heavy pages, switching from unoptimized JPEG to WebP at 1920px typically improves Largest Contentful Paint (LCP) by 0.5–2 seconds and can add 5–15 PageSpeed points.

Yes — always archive the full-resolution original. Web-compressed copies are for serving online; you will need the original if you ever want to resize or re-export at a different quality.
