Why Convert JPG to WebP?
WebP is Google's modern image format, designed specifically for the web. It delivers the same visual quality as JPG at roughly 25-35% smaller file sizes. That's not a minor improvement — it means faster page loads, lower bandwidth costs, and better Core Web Vitals scores.
Since 2020, WebP has been supported by all major browsers including Chrome, Firefox, Safari, and Edge. The compatibility concerns that once held it back are now history. For web use, WebP is simply the superior choice.

WebP Advantages Over JPG
Smaller File Sizes
At the same perceived quality, WebP files are consistently 25-35% smaller than JPG. For a website serving thousands of images, this translates to significant bandwidth savings and faster load times.
Better Compression Artifacts
When compression artifacts do appear (at very low quality settings), WebP handles them more gracefully. You'll see fewer of the blocky distortions that JPG is infamous for.
Animation Support
Unlike JPG, WebP supports animation — like GIF but with vastly better compression. A single format can handle both static images and short animations.
Transparency Option
WebP supports alpha channel transparency, something JPG cannot do. You can have both small file sizes and transparent backgrounds in the same image.
Browser Support
As of 2024, WebP is supported by over 97% of browsers worldwide:
Full support: Chrome, Firefox, Edge, Safari, Opera, Samsung Internet, and all Chromium-based browsers.
Mobile: iOS Safari (14.0+), Chrome for Android, Firefox for Android — essentially all modern mobile browsers.
For the remaining 3% (mostly old Internet Explorer installations), you can serve JPG fallbacks using the HTML picture element.
