Convert iPhone HEIC Photos to PNG
Recent iPhones save photos as HEIC, a format Apple adopted because it stores a great-looking picture in roughly half the space of a JPG. That efficiency is welcome until you move the file off the phone and onto a Windows PC, into an older editor, or up to a service that has never heard of HEIC and simply rejects it. Converting to PNG produces a file that opens on essentially anything, with no plugin or codec hunt required.
PNG is the right target when you care about quality and flexibility rather than file size. It is lossless, so the photo is decoded straight from the HEIC and written out with full detail, no second round of compression smudging the result. That makes it a good fit for pictures you intend to edit, crop or print, or any image where you would rather not give up a single pixel of fidelity.
It is worth understanding why these files keep turning up. Apple made HEIC the default capture format a few iPhone generations ago because it packs the same picture into far less storage than JPG, which adds up over a camera roll of thousands of photos. The friction only appears when the photo leaves the Apple world for a Windows machine, an older program or a website that does not recognise the extension. You can tell an iPhone to shoot in the older format under Settings, Camera, Formats, Most Compatible, but that does nothing for the HEIC photos already sitting on your phone or backed up to a drive, which is exactly the gap this converter fills.
Choosing between PNG and JPG
Choose PNG when quality and editability come first and a larger file is no problem, for photos you will crop, retouch or print and want to keep pristine. Choose HEIC to JPG instead when you want a compact, email-friendly file and a small, invisible quality trade is perfectly acceptable, which is the more common choice for everyday snapshots. If the photos are ultimately bound for a document, HEIC to PDF places them straight into one.
A single batch takes up to 30 HEIC files. A lone photo downloads as a PNG, and a group comes back as a ZIP named to match your originals. Live Photos are converted as the single still frame, not the short clip.
