JPG to WebP Converter: what to know
WebP is a modern image format that every current major browser displays. For photos it typically produces smaller files than JPG at similar visual quality, which means faster pages, less bandwidth and better Core Web Vitals scores for images that dominate a page's loading time.
Converting decodes your JPG in the browser and encodes it as lossy WebP at the quality you choose. Because the JPG was already compressed, you are compressing a second time; a moderate-to-high quality setting keeps the result visually close to the source while still saving space. The saving varies by photo, so compare the sizes before replacing anything.
WebP support outside browsers is good but not universal. Some older desktop software, email clients and print services still expect JPG. For a website, the common approach is to serve WebP and keep JPG as a fallback, or use the HTML picture element so each browser gets the best format it supports.

Tips for the best result
- Resize photos to their display size before converting for the biggest saving.
- Start from the original JPG, not one that has been compressed several times.
- If the WebP comes out larger than the JPG, keep the JPG.
- Use the HTML picture element to serve WebP with a JPG fallback.
