How to Convert JPG to WebP for Faster Websites
Convert JPG images to WebP format for 25-35% smaller files. Browser-based, free, and private — no upload needed.
WebP is Google's modern image format that delivers 25-35% better compression than JPG at equivalent visual quality. Converting your website images from JPG to WebP is one of the easiest performance wins available.
ConvertCraft's Image Converter handles JPG to WebP conversion entirely in your browser. Drop your images, select WebP output, and download optimized files instantly.
WebP supports both lossy and lossless compression. For photos, lossy WebP at quality 80 produces files that are visually identical to JPG at quality 92 — but significantly smaller.
WebP also supports transparency (alpha channel), which JPG does not. This makes WebP a versatile replacement for both JPG and PNG in most web contexts.
Browser support for WebP is universal in 2026 — Chrome, Firefox, Safari, and Edge all support it natively. The only holdout is very old browsers, for which you can serve JPG fallbacks using the HTML picture element.
