Best HEIC Viewer - view heic files on Windows 11?

Windows 11 does not support HEIC image format. You can convert .heic to .jpg so you can easily view them on Windows 11.

A good command-line option is libheif, especially its heif-convert command. It is made for HEIC/HEIF decoding and can convert HEIC or HEIF images to JPG or PNG for free. The libheif example tools include heif-convert, which converts HEIF/AVIF images to JPEG or PNG.

Single HEIC to JPG:

heif-convert input.heic output.jpg

Batch convert all HEIC files in one folder:

for %f in (*.heic) do heif-convert "%f" "%~nf.jpg"

Batch command inside a .bat file:

for %%f in (*.heic) do heif-convert "%%f" "%%~nf.jpg"

After conversion, you can view heic images on Windows 11 now.

A second option is a PowerShell script using Windows.Graphics.Imaging, but it usually depends on Windows being able to decode HEIC first, so the HEIF Image Extensions may still be required. For a clean command-line tool, libheif / heif-convert is the better recommendation as a free heic viewer on Windows 11..
