System Requirements and Compatibility

Any Windows PC from the last 15 years runs it smoothly. The program supports Windows versions from 7 through 11 identically without platform-specific configuration needs. No macOS or Linux versions exist, keeping development focused on Windows optimization.

Core Features and Format Support

This lightweight image viewer opens JPEG, PNG, GIF, TIFF, BMP, and PCX files instantly. RAW camera formats from Canon CR2, Nikon NEF, and Sony ARW work through the PlugIns package. Legacy formats like Amiga IFF, Atari Degas, and OS/2 BMP maintain backward compatibility for archival work.

Batch Image Converter Capabilities

The batch conversion tool processes entire folders with rename patterns and format changes. Convert PNG sequences to JPEG with 85% quality using the `/convert=` command line parameter. Resize operations maintain aspect ratios or force specific dimensions like 1920x1080 for web galleries.

Advanced Tools and Slideshow Functions

Slideshow mode cycles through directories with customizable timing from 1-999 seconds per image. Crossfade transitions and random order options work with background music playback. The thumbnail browser displays 100+ images simultaneously for quick navigation through large photo collections.

EXIF data extraction shows camera settings, GPS coordinates, and modification timestamps. The histogram displays RGB channel distribution for exposure analysis. Red-eye removal and basic color corrections handle common photo fixes without launching external editors.

Plugin Extensions and Additional Codecs

The optional PlugIns package adds support for Adobe Photoshop PSD files, HEIC iPhone photos, and WebP images. Video format thumbnails work with AVI, MP4, and MKV containers. Extended plugin functionality includes OCR text recognition and advanced image effects.

Portable Image Viewer Options

The portable version configuration runs from USB drives without Windows registry entries. Copy the installation folder to removable media for consistent image viewing across multiple computers. Settings save to local INI files instead of system registry keys.

This free software license covers personal and educational use without registration requirements. Commercial environments need separate licensing for business deployment. The Austrian developer maintains source code as proprietary while keeping the program completely free for home users.

Regular updates arrive every 6-12 months with format support additions and Windows compatibility improvements. Version 4.75 added Windows 11 optimization and enhanced RAW codec performance for modern camera files.

The irfanview download delivers essential image viewing functionality in a compact package that starts faster than Windows Photos and handles more formats than default system viewers.
