How the jpg to webp works and best practices for modern web projects.
Why convert JPG to WebP?
JPEG has been the photographic standard since 1992, but WebP uses predictive coding borrowed from the VP8 video codec. At equivalent visual quality a WebP file is typically 25-35% smaller than the JPG it came from.
WebP also handles smooth gradients such as skies and studio backdrops with fewer blocking artefacts than a legacy JPEG encoder at low bitrates.
Browser compatibility
WebP is supported by more than 97% of browsers in use today, including Chrome, Edge, Firefox, Opera and Safari on both macOS and iOS. You can deploy converted .webp images on any modern website without a fallback picture element in most cases.

No. A JPG has no alpha channel, so the converted WebP keeps its solid background. Use the PNG to WebP converter for transparent artwork.
