How to Convert HEIC to JPG on Windows

Why Windows will not open a HEIC file

HEIC is an image wrapped in the HEIF container and compressed with HEVC, the same codec as H.265 video. HEVC is covered by a large patent pool, so anyone shipping a decoder has to license it. Microsoft's answer was to split the support into two Store packages: HEIF Image Extensions, which is free, and HEVC Video Extensions, which is not — and the free one does not work without the paid one for most files.

That is the whole problem. It is not that your PC is old or that the file is broken. Windows simply does not carry the decoder, and the official way to add it costs money for something your phone does for free.

Option 1 — Convert in your browser (nothing to install)

This works on any Windows machine, including a locked-down work laptop where you cannot install anything, because the decoding happens inside the browser using its own HEIC support. No file is sent to a server.

1. Open the HEIC to JPG converter in Edge, Chrome or Firefox.
2. Drag the .heic files onto the page, or click to browse. A whole camera-roll export at once is fine.
3. Leave quality at 90 or above — HEIC files hold a lot of detail and it is worth keeping.
4. Convert, then download the files individually or as a single ZIP.

Option 2 — Buy the Microsoft codec

If you receive HEIC files constantly and want Windows itself to display them, the HEVC Video Extensions package in the Microsoft Store is the official route. Install HEIF Image Extensions first, which is free, then HEVC Video Extensions, which Microsoft charges a small fee for. After that, File Explorer shows thumbnails and Photos opens the files normally.

Worth knowing: some PC manufacturers pre-license HEVC, in which case a device-specific version appears in the Store at no charge. Search the Store for "HEVC" and see which version you are offered before paying.

Option 3 — Stop the iPhone sending HEIC in the first place

If the photos come from someone you can ask, or from your own phone, this is the permanent fix and it takes ten seconds on the phone.

1. On the iPhone, open Settings, then Camera, then Formats, and choose Most Compatible. The camera saves JPG from then on.
2. Then open Settings, then Photos, scroll to Transfer to Mac or PC, and choose Automatic. That converts on export rather than sending the raw HEIC.

• Most Compatible roughly doubles the storage each photo uses — that is the trade.
• Photos already taken stay HEIC. Only new ones are affected.
• The Transfer setting matters even if you leave the camera on High Efficiency, because it converts during the transfer.

Option 4 — Desktop software

Several Windows applications read HEIC without the Store codec because they bundle their own decoder. Recent versions of Adobe Lightroom and Photoshop handle it, and so do a number of free image viewers. This is worth it if you already use one of them; it is a lot of installation if you do not.

Which route to pick

Do not rename the extension

Renaming a .heic file to .jpg changes the label and nothing else. The bytes inside are still HEVC, so Windows still cannot decode it — and now the error is more confusing, because everything claims it is a JPEG. The file has to be genuinely re-encoded.
