JPG to WebP Converter
Convert your JPG images to WebP format — typically 25–35% smaller at the same quality. Faster page loads, better Core Web Vitals, improved SEO. Runs entirely in your browser — no upload, no signup, instant download.
How to convert JPG to WebP (3 steps)
- Drop your JPG files. Files stay in your browser — nothing is sent to any server. Multiple files are supported.
- Choose WebP quality. The default 80% produces files 25–35% smaller than the original JPG. Adjust the slider for a different quality/size trade-off.
- Download your WebP. The output has a .webp extension. Upload to your website, CMS, or CDN — it displays identically to JPG in all modern browsers.
Why WebP is better than JPG for web images
Google developed WebP specifically to make web pages faster. At the same visual quality, WebP achieves a 25–35% smaller file size than JPG by using a more advanced compression algorithm (VP8). Smaller images mean faster LCP (Largest Contentful Paint), which Google uses directly as a Core Web Vitals ranking signal. A 40% reduction in image payload on a product page translates to measurably faster load times — and faster pages rank higher and convert better. As of 2025, WebP is supported by every browser in use by more than 1% of users worldwide.

FAQ
Why should I convert JPG to WebP?
WebP files are 25–35% smaller than JPG at the same visual quality. Smaller images improve Core Web Vitals (LCP), which is a Google ranking signal. All modern browsers support WebP.
Does converting JPG to WebP reduce image quality?
At the same quality setting, WebP and JPG are visually indistinguishable. WebP achieves its smaller file size through a more efficient algorithm, not by discarding more detail.
Do all browsers support WebP?
Yes — Chrome, Safari (since 2020), Firefox, Edge, and all modern mobile browsers support WebP. Global support exceeds 97% in 2025. Only IE 11 and Safari pre-2020 lack support.
Can I convert multiple JPGs to WebP at once?
Yes — drop multiple JPG files at once. Each converts separately and you can download them individually or all together as a ZIP. Conversion runs entirely in your browser.
Does WebP work for WordPress or e-commerce images?
Yes. WordPress 5.8+ and most e-commerce platforms (Shopify, WooCommerce) natively support WebP uploads.
