O que é JPG → WebP?
A JPG to WebP converter transforms JPEG images into Google's modern WebP format, reducing file size by 25–35% while maintaining equivalent visual quality. WebP was developed by Google specifically for the web, using advanced compression techniques derived from the VP8 video codec. In 2026, WebP is supported by all major browsers (Chrome, Firefox, Safari, Edge) and is the recommended image format for websites by Google's PageSpeed Insights.
Por que converter JPG → WebP?
Website performance is the primary reason to convert JPG to WebP. Google's Core Web Vitals directly affect search rankings, and image size is the biggest factor in page load time. A typical blog post with 10 images at 200 KB each (JPG) uses 2 MB of bandwidth. Convert those to WebP at 130 KB each and you save 700 KB — a 35% reduction that directly improves your Largest Contentful Paint (LCP) score. Beyond SEO, faster loading means lower bounce rates: Amazon found that every 100ms of latency costs 1% in sales. WebP also supports transparency (unlike JPG) and animation (like GIF but much smaller).
Ideal para:
- Website and blog images (Core Web Vitals improvement)
- E-commerce product photos (faster page loads = more sales)
- Progressive web apps (PWA)
- Any image served over the internet
- Email newsletter images (smaller = faster delivery)
Detalhes técnicos
WebP supports both lossy and lossless compression. TweakFiles uses lossy compression by default (matching JPG behavior) with a quality setting you can adjust. At quality 80%, WebP produces files roughly 30% smaller than an equivalent quality JPG. WebP supports images up to 16,383 × 16,383 pixels. For images larger than this, the conversion will fail. Browser support is now universal: Chrome (since 2014), Firefox (since 2019), Safari (since 2022), Edge (since 2018).
