JPG to WebP Converter - Free Online Tool

A JPG to WebP converter transforms JPEG images into WebP, Google's modern image format optimized for the web. WebP delivers the same visual quality as JPG at 25–35% smaller file sizes, making websites load faster. All major browsers support WebP, making it the go-to format for web images. This tool processes images entirely in your browser for instant, private conversions.

1. Upload your JPG file: Drag and drop or click to select a JPEG image from your device. Files up to 10MB are supported.
2. Adjust quality settings: Use the quality slider to balance file size and image clarity. WebP maintains quality well even at lower settings.
3. Download your WebP: Click the download button to save the converted image instantly to your device.

• Smaller file sizes: WebP images are significantly smaller than equivalent JPGs, reducing bandwidth and storage.
• Faster page loads: Smaller images mean faster websites, improving user experience and SEO rankings.
• Modern standard: WebP is supported by Chrome, Firefox, Safari, Edge, and all major platforms.

Use case 1: Optimize website images

Convert your blog photos, hero images, and thumbnails to WebP to dramatically improve page load times.

Use case 2: Reduce cloud storage costs

Store image archives in WebP format to save 25–35% on cloud storage bills without visible quality loss.

Use case 3: Improve Core Web Vitals

Google's page experience signals reward fast-loading pages. Converting images to WebP directly improves LCP (Largest Contentful Paint) scores.

• File size: WebP is 25–35% smaller than JPG at the same quality.
• Quality: Both formats offer comparable visual quality.
• Transparency: JPG doesn't support it; WebP does.
• Animation: JPG doesn't support it; WebP does.
• Browser support: JPG works everywhere; WebP works in all modern browsers.

WebP not opening on older system

Windows 10 (pre-2018) and older macOS versions may not display WebP natively. Update your system or use a modern browser to view the files.

File size not much smaller

For already heavily compressed JPGs, WebP savings are reduced. The biggest improvements come from converting high-quality or uncompressed JPGs.

Image looks softer than original

WebP uses different compression algorithms. Increase the quality slider to 85–95 for images where fine details matter.

• Quality 75–85 works for most photos. Use 85–95 for images with text or fine details.
• Always keep your original JPGs as backups—conversion is lossy.
• For websites, serve WebP with JPG fallback using the <picture> element for older browser support.
• Test conversions on a few sample images before batch processing.

• Lossless conversion with JPG to PNG.
• Convert PNG images with PNG to WebP.
• Reverse conversion with WebP to JPG.
• Convert Apple photos with HEIC to WebP.

All image processing happens entirely in your browser using client-side JavaScript. Your photos are never uploaded to any server, stored, or transmitted. Close the tab and your data is gone.
