HEIC vs. JPG: which should you actually use?

HEIC is a modern image container commonly produced by Apple devices. It can retain good visual quality at a smaller size than an equivalent JPEG, which makes it useful as a camera-original format.

JPG is older and lossy, but its compatibility is difficult to beat. Browsers, email clients, document tools, printers, content-management systems, and marketplace upload forms generally accept it without an extra conversion step.

Keep the HEIC original when it is your best-quality source and the next tool in your workflow supports it. Converting a lossy image repeatedly cannot restore detail and may introduce new compression artifacts.

Create a JPG delivery copy when the file needs to leave an Apple-centric workflow. Use the converted copy for sharing, but retain the HEIC source if you may edit or export it again.

Treat conversion as creating a derivative, not replacing the source. Keep the original, export one JPG at the dimensions and quality the destination needs, inspect fine detail and gradients, and only then distribute the copy.

Convyx reads HEIC and converts it to supported image targets. HEIC is source-only because the current image stack does not provide a dependable HEIC encoder; the product does not pretend otherwise.
