What changes when converting
Converting JPG to WebP does not involve renaming the extension. The image is re-encoded into the output format. Therefore the final size and quality may change depending on the level you choose.
Why WebP can be useful on a website
WebP is intended for web images and can produce small files with good visual quality. On a page with many photos, reducing the weight of each asset can help limit the total amount of data transferred.
Take care of repeated conversions
If you convert a lossy image multiple times, each new encoding can introduce degradation. Whenever you can, start from the higher quality original file instead of converting an already highly compressed copy.
Compare before replacing
Look at the size of the original JPG and the resulting WebP. Then compare areas with texture, shadows and gradients. If the savings are minimal or you notice defects, keep the original or adjust the quality.
Compatibility and support
Modern browsers handle WebP widely, but if you are working with an older system or a specific editing flow, check that it accepts the format before replacing all your files.
