WebP files are typically 25–35% smaller than JPG at the same visual quality, making them ideal for web use and faster page loads.
WebP is supported by all modern browsers (Chrome, Firefox, Safari, Edge). Older software may not support it.
No. All conversion happens in your browser. Your files never leave your device.
We use 92% WebP quality by default, which is visually indistinguishable from the original for most images.
What is JPG to WebP?
JPG to WebP conversion is one of the most impactful performance optimizations you can make for a website. Google's PageSpeed Insights and Core Web Vitals metrics specifically recommend serving images in next-gen formats like WebP, and the evidence is compelling: WebP typically produces files 25–35% smaller than JPG at equivalent visual quality. For a page with ten 200KB JPG images, switching to WebP could save 500–700KB per page load — translating directly to faster LCP (Largest Contentful Paint) times and better search ranking potential. Our converter uses the Canvas API running entirely in your browser, making it fast, private, and free. The converted WebP files are ready to drop into your website, CMS, or CDN immediately.

Frequently Asked Questions
How much smaller is WebP compared to JPG?
Google's research shows WebP is typically 25–34% smaller than JPG at equivalent perceptual quality. The exact saving depends on image content — photographs with complex textures see the largest gains.
Is WebP supported by all browsers?
All modern browsers support WebP: Chrome, Firefox, Edge, and Safari 14+. For older Safari support, use the HTML <picture> element with a JPG fallback.
Does WebP improve SEO?
Yes, indirectly. Smaller images load faster, which improves Core Web Vitals metrics like LCP. Google uses Core Web Vitals as a ranking signal, so faster-loading pages can rank higher.
Can I use lossless WebP instead of lossy?
Yes. The tool supports both lossy WebP (smaller files, minimal quality loss) and lossless WebP (same file size advantage over PNG with perfect quality).
Are my JPG images uploaded to a server during conversion?
No. The entire conversion runs in your browser using the Canvas API. Your images are re-encoded in browser memory and the WebP file is downloaded directly — no server processes your data.
