Why Convert JPG to WebP?
Developed by Google, WebP is a modern image format designed for efficient web delivery. It supports lossy and lossless compression, transparency and animation.
Often Smaller Files
WebP often produces smaller files than JPEG at comparable visual quality thanks to its modern lossy and lossless compression. Actual savings depend on the image content and compression settings.
Faster Page Loading
Smaller image files can reduce the amount of data your visitors download, which may help pages load faster, especially on slower connections.
Recommended by PageSpeed Insights
PageSpeed Insights recommends serving next-generation image formats like WebP. Using efficient formats can help pages load faster, though the result depends on many factors.
Widely Supported in Modern Browsers
WebP is natively supported in Chrome, Edge, Firefox, Safari and iOS Safari, so converted images work across current browsers without plugins.
Lower Bandwidth Usage
For sites serving many images, smaller files can reduce bandwidth and CDN usage. Actual savings depend on your images and compression settings.
Private, In-Browser Conversion
The converter runs entirely in your browser. Your images are not uploaded to a server or stored in the cloud.

| Lossless Mode Support | Primarily lossy compression | Yes — WebP supports both lossy and lossless compression |
| Animation Support | No — standard JPEG is static | Yes — WebP supports animation |
| Page Speed | Larger image files can require more data to be transferred | Smaller image files can reduce transfer size and may help improve loading performance |
| Browser Compatibility | Universally supported, including legacy browsers | Widely supported across modern browsers, including Chrome, Edge, Firefox, Safari and iOS Safari |
Actual file-size savings vary depending on the image, dimensions, content and compression settings.
WebP can provide smaller image files at comparable visual quality, but the actual reduction depends on the source image and compression settings. WebP supports both lossy and lossless compression, transparency and animation.
