About WebP → JPG
When should I convert WebP to JPG?
Most modern software supports WebP, but some older CMSs, image-print kiosks, marketplaces and document templates still demand JPG. Converting to JPG also strips animation and alpha — a safer baseline for compatibility.
What happens to transparent WebPs?
JPG can't store transparency, so verto fills transparent areas with white before encoding. The transparency warning shows up automatically when the source has an alpha channel.
Is the output quality the same?
JPG is lossy; WebP is usually saved with lossy compression too. You'll see a small generational loss when re-encoding. Keep the quality slider at 85 or higher to keep that loss invisible for photos.
