How to convert

  1. Open the converter — output is preset to WebP.
  2. Drop in your JPGs, or your site's whole images folder.
  3. Add a long-edge resize if the originals are bigger than they're displayed.
  4. Export.

What you actually gain

WebP generally reaches the same visual quality as JPG in 25–35% fewer bytes. On a page carrying a dozen photographs that's a real reduction in load time, and load time feeds directly into Core Web Vitals and search ranking.

Resize first, though. The format change is worth a third. Serving a 4000px photo into a 800px slot is costing you far more than that — fix the dimensions and you'll often save more than WebP does.

When not to

Don't send WebP to clients, don't upload it to marketplaces that haven't confirmed support, and don't use it for print. It's a delivery format for the web and nothing else — for anything leaving your hands, use JPG.

Common questions

Does converting JPG to WebP lose quality?

There's a small generation loss, as with any lossy re-encode, but it isn't visible at sensible settings — and the file is meaningfully smaller. Work from the highest quality original you have rather than an already-compressed copy.

Will it make an old, blurry JPG look better?

No. Whatever the JPG threw away is gone for good. WebP stores what's left more efficiently; it doesn't reconstruct anything.

Can I convert my whole images folder?

Yes — drag the folder in, subfolders included, and export as a zip. See batch converting a folder.
