WebP usually produces noticeably smaller files than JPG at the same quality, with support across all modern browsers. It’s a safe, well-established choice for speeding up websites.
Conversion happens locally in your browser, so your images stay private.
How to convert JPG to WebP
- Drop your .jpg files above.
- Set the quality level.
- Download your WebP files (or a ZIP).
Why convert JPG to WebP?
WebP balances size and compatibility well — typically 25–35% smaller than JPG at the same visual quality, and supported by every current browser. Smaller images mean faster pages, better Core Web Vitals, and lower bandwidth, which is why WebP is a popular default for web delivery.
WebP vs AVIF for the web
Both shrink JPGs significantly. WebP is the safe, well-established choice with the widest support; AVIF compresses even better but is a little newer. If your audience is on modern browsers and you want the absolute smallest files, AVIF is worth considering — otherwise WebP is an easy win.
Choosing a quality level
Around 75–80 is a good default for photographs — visually close to the original at a fraction of the size. Lower the slider to save more space for thumbnails, or raise it when you need maximum fidelity.
