What Is HEIC and How to Convert, Compress, and Edit iPhone Photos

HEIC is the image format many iPhones use because it can keep photos sharp while using less storage than older JPG files. The catch is compatibility: some websites, design tools, and upload forms still expect JPG, PNG, or WebP.

The safest workflow is to keep the original HEIC as your source, then export a task-specific version. Use JPG for broad compatibility, WebP or AVIF for lighter web images, and PNG when transparency or crisp edges matter.

HEIC is also not only a Convert problem. You may want to compress a large iPhone photo, resize it for social media, remove a background from a product shot, or clean up an unwanted object. Lumli supports HEIC as an input across the tool workflow so you do not have to convert first every time.
