Why would I need to convert WebP to JPG?
WebP is common for images downloaded from websites (it's Google's preferred web format), but plenty of older software, some email clients, and a handful of platforms still don't open WebP files directly. Converting to JPG or PNG turns it into a format that opens everywhere without a second thought.
JPG or PNG — which should I convert to?
JPG for ordinary photos — smaller files, universally supported. PNG only if the WebP image has transparency you need to keep (JPG has no transparency support) — otherwise PNG files end up considerably larger than JPG for the same photo content.
Will converting from WebP lose quality?
If the source WebP was saved lossy (the common case), converting to JPG re-encodes already-compressed data — a small additional quality loss, similar to converting between any two lossy formats. If you need the cleanest possible result, use a high JPG quality setting rather than the default.
