Convert JPG to WEBP — 60% Smaller Files for the Web

JPG files are the workhorse of the web, but they're also bloated. A 2MB JPG can become a 700KB WEBP with identical visual quality. That's the difference between a page that loads in 1.5 seconds and one that loads in 4.

Converting JPG to WEBP is the first thing you should do when optimizing images for the web.

Why Convert JPG to WEBP?

  • 60% smaller on average compared to equivalent quality JPG
  • Same visual quality — no noticeable difference to the human eye
  • Universal browser support — works in Chrome, Firefox, Safari, Edge
  • Transparency support — unlike JPG, WEBP supports alpha channels

The browser support for WEBP is excellent. 97%+ of global browsers can render WEBP. The remaining 3% are mostly IE11 users, and lossy WEBP actually has some support in IE11 too.

How to Convert JPG to WEBP

  1. Open ImageConvert
  2. Select your JPG file (drag and drop or click to upload)
  3. Choose WEBP as the output format
  4. Set quality to 85 (default, good for most web uses)
  5. Click Convert & Download

That's it. Your 2MB JPG becomes a 700KB WEBP.

Quality Settings Explained

Quality File size Best for
90–100 Large (near lossless) Print-quality web, hero images
80–89 Medium General web use, product photos
70–79 Small Thumbnails, high-volume image pages
Below 70 Very small Generally too low quality

For most web uses, quality 85 is the sweet spot. You get near-lossless quality with excellent compression.

Comparing JPG to WEBP at Equal Quality

We tested a 4MP landscape photo across formats:

  • JPG at quality 85: 1.8 MB
  • WEBP at quality 85: 650 KB ← 64% smaller
  • JPG at quality 60: 800 KB (visibly degraded)
  • WEBP at quality 60: 180 KB (near-lossless visually)

The WEBP advantage is significant even at high quality settings. A quality 85 WEBP is both smaller AND looks better than a quality 85 JPG.

Adding WEBP to Your Website

Modern browsers automatically display WEBP files. Just upload the converted files to your site and reference them in your HTML:

<img src="photo.webp" alt="Description" width="800" height="600">

For maximum compatibility, use the <picture> element with a JPG fallback:

<picture>
  <source srcset="photo.webp" type="image/webp">
  <img src="photo.jpg" alt="Description">
</picture>

When JPG is Still the Answer

JPG remains better when:

  • You're targeting IE11 and can't use picture fallbacks
  • Maximum email compatibility is required
  • The image will be heavily edited multiple times

But for new web projects, WEBP should be your default format for all photographs and complex images.
