About the output format
When JPG is the right output
JPG is the default format for photographs — 24-bit colour, lossy compression tuned for continuous-tone imagery, universally supported. Ubiquity is its main strength: government portals, e-commerce marketplaces, print labs, and CMS uploaders that don't say what format they want will accept JPG. The trade-offs: no transparency, no lossless option, compression artefacts around sharp edges (text, logos). Use JPG when the source is a photograph and the destination doesn't require a transparent background.
