Yes, for most cases. WebP is 25–34% smaller than JPEG at the same visual quality and is supported by every modern browser — Chrome, Firefox, Safari 14+, Edge. The practical impact: faster page loads, lower bandwidth costs, and better Core Web Vitals scores. Use a JPEG fallback in a <picture> element only if you need to support Internet Explorer or very old iOS Safari (pre-2020).
Yes — WebP supports full alpha-channel transparency in both its lossy and lossless modes. A transparent WebP is typically 25–35% smaller than the equivalent PNG. For logos and icons on websites, switching from PNG to WebP with transparency is a straightforward size win with no visual trade-off.
Older versions of Photoshop (pre-2022) don't natively support WebP. Your options: use PortImg to convert the WebP to PNG or JPEG first, then open that in Photoshop; install the free WebP Photoshop plugin from Google; or update to Photoshop 23.2 or later, which added native WebP support.
Slightly, because WebP lossy uses a different compression algorithm than JPEG — you're re-compressing already-compressed data. Set the WebP quality to 85–90% (not the default 75%) when converting from JPEG to minimise any generational quality loss. For the freshest result, always convert from the original uncompressed or RAW source rather than from an existing JPEG.
