About JPG to WEBP

WEBP stores the same photo in roughly 25 to 35% fewer bytes than JPG at comparable quality, which is why it is the go-to format for websites that must load quickly on mobile data. This tool re-encodes your JPGs as WEBP right here in the browser, ready to upload to WordPress, Shopify or your own site. No file ever leaves your device.

How to use JPG to WEBP

  1. Add the JPG photos you plan to serve on your website.
  2. Confirm that Convert to is set to WEBP.
  3. Set Quality: around 80% suits web pages, 92% suits photos people will zoom into.
  4. Click Convert to WEBP and download the batch as a ZIP.

What people use it for

  • Cutting page weight on a product catalogue before uploading it to a store.
  • Shrinking blog images so pages score better in PageSpeed Insights.
  • Preparing hero and banner images for a site that serves WEBP with a JPG fallback.
  • Reducing how much storage a photo gallery eats on a shared hosting plan.

Good to know

Chrome, Edge, Firefox, Android and Safari from iOS 14 onwards all display WEBP. Very old browsers and some desktop apps do not, so keep your JPG originals as a fallback. This is a lossy re-encode of an already lossy JPG, so avoid going below about 75% if the photo has smooth gradients or small text.

Frequently asked questions

Is WEBP safe to use on a public website?
Yes. Every browser released in recent years renders WEBP, including Safari on iOS 14 and later. Keep JPG copies only if you must support very old devices.
How much smaller will the files be?
Typically 25% to 35% smaller than the JPG at visually similar quality, and sometimes more for photos with large smooth areas such as sky or a studio background.
Does Google prefer WEBP images?
Google does not rank a file format, but smaller images load faster, and loading speed is part of Core Web Vitals, which does feed into search performance.
