JPG (JPEG) is a compact, lossy image format ideal for photographs and web images where small file size matters. WebP is a modern image format that's roughly 25–35% smaller than JPG or PNG at similar quality, built for fast-loading websites. File Converts turns your JPG into WebP right in your browser — no upload, no sign-up, and no daily limit. Because the conversion runs on your own device, even sensitive files stay private, and it keeps working offline once the page has loaded.
Best for
- Reducing photo file sizes to speed up a website
- Serving smaller images without a visible quality drop
- Cutting bandwidth on image-heavy pages or galleries
Good to know
WebP is usually smaller than JPG at the same visual quality, which is why it's the go-to web format for photos. Both are lossy, so avoid repeatedly converting back and forth. Very old browsers and some legacy software don't support WebP — keep a JPG fallback where that matters.
