How to convert JPG to WebP

If a page-speed report is telling you to “serve images in next-gen formats”, this is the task it means. WebP stores the same photo in roughly 25–35% fewer bytes than an equivalent-quality JPG.

Here's how to convert JPG to WebP free in your browser, and how much it actually helps.

Open the JPG to WebP tool

Convert JPG to WebP in your browser

Photos are re-encoded on your own device, which matters when you're preparing client work or unreleased product shots.

  1. 1Open the free JPG to WebP converter.
  2. 2Drag in your JPGs, or click to browse for them.
  3. 3Each is re-encoded as a high-quality WebP.
  4. 4Download a single WebP, or a ZIP if you converted a batch.

What this does for page speed

Images are usually the largest thing a page downloads, so cutting them by a third cuts total page weight by close to the same proportion. The metric that moves is Largest Contentful Paint, which is one of the Core Web Vitals Google uses as a ranking signal.

It is a real improvement, not a decisive one. WebP conversion helps a page that is slow because of image weight; it does nothing for a page that is slow because of render-blocking scripts.

Browser support is no longer a concern

Chrome, Edge, Firefox, Opera and Safari 14+ all display WebP, which covers effectively every browser in current use. Keeping a JPG fallback is only worth the effort if you genuinely need to support very old clients.
