The short answer
JPG remains the safest choice for universal compatibility, while WEBP is usually the better delivery format for modern websites. WEBP can preserve comparable photographic quality at a smaller file size and also supports transparency. Keep an original master and serve an optimized copy.
Compare the formats
JPG uses lossy compression and is ideal for photographs. It does not support transparency. WEBP supports both lossy and lossless compression, transparency, and animation. Current browsers support WEBP broadly, but older editing tools may still work more reliably with JPG.
A practical workflow
Resize the source to its real display dimensions, convert it to WEBP at a sensible quality, and inspect detailed areas such as hair, text, gradients, and product edges. Keep the JPG as a fallback only when your publishing platform or audience requires it.
Try the conversion
Use the JPG to WEBP tool to compare file size and appearance before replacing live images.

Conversion is only one part of the workflow. Review the output in the system where it will be used, confirm that important details remain accurate, and keep the original source until the final version has been verified.
