Why convert JPG to WEBP?
WEBP is a modern image format built for the web. It usually provides smaller file sizes than JPG while keeping images looking sharp and clean. That means pages load faster, users wait less, and you use less bandwidth.
Converting JPG photos to WEBP with GhostConvert is especially useful when you:
- Optimize a blog, landing page, or e-commerce store for speed.
- Prepare images for modern browsers and app frontends.
- Want smaller image payloads in frameworks like Next.js, SvelteKit, or SPA builds.
- Care about Core Web Vitals and Lighthouse performance scores.

How JPG → WEBP conversion works
- Upload a JPG photo from your phone, laptop, or tablet.
- GhostConvert decodes the JPG and re-encodes it using WEBP compression.
- The encoder balances quality and file size so the image still looks good on modern screens.
- You download a WEBP image that’s lighter and ready to use on the web.
This tool focuses on simple, single-image conversions — but you can run multiple images through quickly as needed for a batch of posts or a small gallery.
Tips for best results
- Start with the highest-quality JPG you have to avoid visible compression artifacts.
- Use WEBP on image-heavy pages like galleries and product grids to cut load time.
- Keep original JPGs as a backup if you plan multi-format delivery (JPG + WEBP + AVIF).
