Many teams overuse JPG for every image and then wonder why screenshots or diagrams look fuzzy. The image type should decide the format, not the default export button.
Photos tolerate lossy compression well, but UI captures, charts, and images with text generally need lossless treatment or they degrade quickly.
PNG keeps edges sharp and supports transparency, but file sizes can grow fast. JPG reduces file size aggressively and is universally accepted, but it cannot preserve transparency and can damage detail in graphics.
WebP often gives the strongest size-to-quality tradeoff for modern web delivery. It is especially useful when you want smaller assets without giving up as much quality as a naive JPG export.
If the output is going to a browser-first surface, test PNG to WebP or JPG to WebP first. If the destination is an email workflow, office document, or older upload target, JPG is often the safer fallback.
Use a separate compression step after format conversion so you can validate quality and file size as distinct decisions instead of combining them blindly.
