Yes, but IrfanView needs HEIC/HEVC support installed
IrfanView's current format list includes HEIC, and its FAQ explains how to load HEIC files. IrfanView needs a compatible HEIC/HEVC codec or the Microsoft HEIF/HEVC extensions available for the relevant Windows version.
Current IrfanView HEIC support
IrfanView's official site currently lists version 4.75 and includes HEIC/AVIF in its supported image-format table.
The format listing alone does not mean every Windows installation can decode HEIC immediately. IrfanView marks HEIC as PlugIn-supported, and its FAQ separately states that HEIC loading requires an installed HEVC extension or codec path.
IrfanView HEIC setup on Windows 10 and Windows 11
For Windows 10/11, IrfanView's official FAQ points to Microsoft Store extensions.
- Install HEIF Image Extensions from Microsoft Store.
- For IrfanView's documented Windows 10/11 Store path, install HEVC Video Extensions from Device Manufacturer as well.
- Close and reopen IrfanView, then load the HEIC image again.
IrfanView also documents HEIC codec options for older Windows
IrfanView's FAQ lists alternative HEIC codec routes for Windows 7 and Windows 8 in addition to the Microsoft Store path for newer Windows versions.
Those alternatives are IrfanView-specific dependency guidance and do not imply that every HEIC app supports the same Windows versions.
