Why convert PNG to JPG
Screenshots and exported graphics are often PNG files of several megabytes. JPG at 85–90% quality looks identical for photos and most screenshots at a fraction of the size, which matters for government portals that cap uploads at 100–200 KB, email attachments and page speed.
Transparency and quality
JPG has no transparency, so transparent areas are filled with white. Quality 90 is visually lossless for most images; 70–80 gives the best size trade-off; below 60 shows visible artefacts on text and edges.
