About HEIC to JPG conversion
iPhones and iPads save photos as HEIC by default. HEIC files are small, but many Windows apps, websites and online forms won't accept them. Converting to JPG makes your photos open everywhere.
Vimorby decodes HEIC right in your browser. Safari uses its built-in decoder, and other browsers use a WebAssembly build of the open-source libheif library that loads only when you add a HEIC file. Your photos are never uploaded.
Expect the JPG to be larger than the HEIC, because HEIC uses more efficient compression. Use the Size & quality options to shrink the result. Photos are rotated correctly, and location data and other metadata are removed.
