JPG to WEBP Converter · runs entirely on your device
This tool converts JPG images to WEBP directly in your browser. The file is decoded onto an HTML canvas and re-encoded as WEBP, so it never touches a server and the conversion finishes in milliseconds.
WebP produces significantly smaller files than JPG or PNG at the same visual quality, which improves page-load performance and Core Web Vitals.
JPG is a lossy raster format that compresses photographic images by discarding detail the human eye is unlikely to notice. Quality is set on a 0–100 scale; most web images use 60–85.
Best for: Photographs and complex images with smooth colour gradients, where small file size matters more than pixel-perfect accuracy. Trade-offs: No transparency, visible artefacts at low quality, and every re-save loses a little more detail (generation loss).
WebP is a modern image format from Google that offers both lossy and lossless modes plus alpha transparency and animation. At matched quality it is typically 25–35% smaller than JPG or PNG.
Best for: Web images where page-load speed and Core Web Vitals matter; it replaces both JPG and PNG in one format. Trade-offs: Older software and some social platforms still do not accept WebP, so a JPG or PNG copy is sometimes needed.
