If you are putting images on a website, WebP is the easy win: typically 25 to 35 percent smaller than JPG at the same visual quality, and supported by every major browser. Drop your JPGs below and they are re-encoded as WebP on your own device: nothing is uploaded.

Smaller images mean faster pages, and faster pages rank and convert better. WebP reaches the same visual quality as JPG in a meaningfully smaller file, which is why performance audits keep recommending it. For photos destined for a website, converting JPG to WebP is one of the cheapest speed improvements available.
WebP encoding happens with your browser's built-in encoder; current Chrome, Edge, and Firefox all export WebP natively. In a browser without WebP export support, the output falls back to PNG per the web standard, so check the saved file's extension if you use an unusual browser. And because your JPG is already lossy, quality lost earlier cannot be restored; the converter simply re-encodes what is there at the quality you choose.
Once converted, the files behave like any other image: reference the .webp in your markup and every major current browser will display it. Two habits keep the benefit real. Convert from the largest, cleanest original you have rather than from a copy that has already been compressed several times, since stacking lossy encodings is what makes images look soft. And match the pixel dimensions to the largest size the image will ever be displayed at, roughly doubled for high-density screens; serving a 4000 pixel wide photo into a 600 pixel slot wastes far more bandwidth than any format choice can recover. Our guide to size versus quality covers the ordering.
Typically 25 to 35 percent smaller at comparable visual quality, though it varies by image. Detailed photos compress better than images that are already tiny.
Every major current browser displays WebP, so serving it on a website is safe. Creating WebP in this tool relies on your browser's encoder; current Chrome, Edge, and Firefox all export it natively.
For a website, yes, it pays off in load time. For personal archives, JPG remains the safer long-term choice because every device and program opens it.
For practical purposes, no. Every major current browser displays WebP, and search engines index WebP images normally. A fallback only matters if you must support genuinely ancient software.
The opposite, if anything. Smaller images make pages load faster, and page speed is part of how search engines assess a page. What matters is that the image is reachable, has sensible alt text, and is not larger than it needs to be.
