Why does it say a decoder is loading?

Safari can open HEIC by itself. Other browsers cannot, so a small decoder is downloaded once and used locally.

A little, as with any conversion from HEIC to JPG. Use PNG for a lossless copy at a much larger size.

HEIC to JPG

Convert iPhone HEIC photos to JPG or PNG, or straight into a PDF.

Loading the tool…

iPhones save photos as HEIC, which many websites, forms and older programs cannot open. Convert one or a whole batch to JPG or PNG, or turn them straight into a single PDF. The conversion runs on your device; the photos are never uploaded.

How it works

Drop in the HEIC photos.
Choose JPG, PNG or one PDF, and a quality level.
Click Convert and download the file or ZIP.
