Convert HEIC to JPG: the method that actually works

1What is a HEIC file?

HEIC stands for High Efficiency Image Container. It is the image container Apple has used by default since iOS 11 — that is, since 2017: photos taken on a recent iPhone are HEIC files unless you changed the setting.

Inside that container sits the HEVC video codec, also known as H.265. It is what makes the file roughly half the size of an equivalent JPEG. It is also the source of the problem: HEVC is covered by several patent pools, and shipping it in a browser means the vendor has to pay royalties.

You will also come across the .heif extension, which is the generic name for the format, and .hif. All three share exactly the same playback constraints.

2Can Pixora Viewer open a HEIC?

No, and it is better to say so plainly. Pixora Viewer does not decode any format itself: it relies on your browser engine. A format the browser refuses is therefore a format Pixora cannot show, whichever service you use.

The practical consequence is worth knowing before you waste time: a .heic file placed in a folder will not appear in the slideshow. The viewer only lists formats it can handle — JPG, PNG, WebP, AVIF, GIF, BMP, TIFF and a few others. If your folder contains nothing but HEIC files, you will see a “No media found” message. That is not a malfunction: it is the intended behaviour.

So the workflow is the opposite of what you might expect: convert your photos to JPG first, then open the folder in the viewer. Conversion is quick and happens entirely on your machine, as explained below. The viewer deliberately accepts only what it can display, so that you are never left staring at a blank screen.

3Which browsers display a HEIC, and since when?

Browser	Minimum version	Display in a page
Safari (macOS)	17 (Sonoma, September 2023)	yes
Safari (iOS)	17 (September 2023)	yes
Chrome	none	no
Edge	none	no
Firefox	none	no
Opera	none	no

A widespread confusion is worth clearing up here: older macOS and iOS versions could already decode a HEIC inside their own system apps — Preview, Photos — and had done so since 2017. Displaying one inside a web page is an entirely different matter, and only became possible with Safari 17 in 2023.

4Why do browsers refuse HEIC?

The reason is legal, not technical. HEVC is covered by several patent pools, and any vendor embedding it must carry those royalties. Google, Mozilla and Microsoft therefore chose not to ship it, leaving the operating system to handle it where it can.

Firefox illustrates this position best: the request to support HEIF has been open since 2017 and remains at low priority, with no engineer assigned and patents cited as the explicit blocker. There is no reason to expect this to change in the near term — which is why conversion remains the only practical answer.

5How to open a HEIC on Windows

Windows cannot open a HEIC out of the box, because the HEVC codec is not included. Support is added through two Microsoft Store extensions, and the confusion over their pricing is common: the container and the decoder are two separate packages.

Install HEIF Image Extensions, which is free: it teaches Windows to recognise the HEIF container.
Then install an HEVC decoder. Search for HEVC Video Extensions from Device Manufacturer: that is the free variant, intended for devices that already carry a licence. The paid version, around one dollar, also works but is not necessary when the free one is offered.
Restart File Explorer. Thumbnails and the spacebar quick preview will then display your HEIC files normally.
If no free variant is available in your region, your device has no licence to reuse. A third-party player such as VLC bundles its own codecs and will display the image without you buying anything.

Whether the free variant is available depends on your device and your region, and sources contradict each other on this point — online converter vendors have every incentive to declare it gone. When in doubt, VLC is the option that depends on neither a store nor a licence.

6How to convert a HEIC to JPG without uploading it

Conversion is a purely local operation, and you need no online service at all. It is actually preferable that way: a web converter receives your photos, and family pictures have no business sitting on a stranger's server. Every method below works offline.

On macOS, open the file with Preview, then use File → Export and choose JPEG. For a batch, Preview can process a whole folder at once.
On Windows, once the extensions are installed, the Photos app offers “Save as” with the JPEG format. File Explorer can also convert directly.
On iPhone, you can avoid creating HEIC files in the first place: open Settings → Camera → Formats and choose Most Compatible. The device will then produce JPEG files — heavier, but universal.
Sharing a photo over AirDrop or Messages often converts it to JPEG automatically, depending on the recipient's device. Check the extension of the file you received before assuming it was converted.

7Should you convert, or keep the HEIC?

Keep the original. The HEIC is your digital negative: it holds the highest-quality data, and conversion only works in one direction. Deleting the original after converting amounts to throwing away the best version of your photo.

Convert a copy to high-quality JPEG — 90 or above — for anything that needs to travel: email, upload, printing, or displaying in a slideshow. At that quality level the difference is invisible to the eye, while the gain in compatibility is total.

8Frequently asked questions

Can any browser display a HEIC in 2026?

Just one: Safari, from version 17 on macOS Sonoma and iOS 17. Every other browser — Chrome, Edge, Firefox, Opera — cannot, in any version. This is a decision driven by HEVC patents, not a technical delay that the next release would fix.

Why does my iPhone produce HEIC photos?

Because it is the default since iOS 11: HEIC takes roughly half the space of a comparable JPEG, which matters on a device with limited storage. You can switch back to JPEG in Settings, Camera, Formats, by choosing “Most Compatible”.

Can I view a HEIC in Pixora Viewer?

No. Pixora Viewer relies on the browser engine and decodes nothing itself. A .heic file is therefore not listed in the slideshow; if the folder holds nothing else, the viewer reports that no media was found. Convert a copy to JPG first.

Does converting a HEIC to JPG degrade the image?

At quality 90 or above, the difference is not visible to the eye. The conversion is still irreversible: a JPEG does not retain every bit of data in the HEIC, including part of the colour-depth information. Always keep the original alongside the converted copy.

Are HEIF and HEIC the same thing?

HEIF is the generic format, HEIC the variant Apple popularised, which uses the HEVC codec. You will also see the .hif extension. Playback constraints are strictly identical across all three extensions.
