Which converter do I need?

If the file came from an iPhone, it is almost certainly HEIC — start with HEIC to JPG. If it came from a website (right-click → save image in Chrome), it is often WebP — use WebP to JPG. Screenshots are PNG, and converting them with PNG to JPG usually cuts the size by 60–80%.

If a form rejects your file, check the extension before converting: many portals accept JPG only, some accept PNG, and very few accept HEIC, WebP or AVIF. When in doubt, JPG is the format that opens everywhere.
