What is IrfanView?

IrfanView is a fast, compact, and free image viewer for Windows that opens, views, edits, and converts virtually every image format imaginable with speed and simplicity that bloated commercial alternatives cannot match—making it the essential tool for anyone who regularly views photos, manages image collections, performs quick edits, or needs reliable format conversion without Adobe Photoshop’s complexity or cost. Created by Irfan Škiljan in 1996 and continuously developed for nearly three decades, IrfanView has become one of the most downloaded Windows applications with over 100 million users worldwide who appreciate its combination of lightning-fast performance, comprehensive format support, useful editing tools, and completely free availability without advertisements or feature restrictions.

IrfanView excels at opening images instantly—even large RAW files from digital cameras—with negligible memory usage compared to heavyweight image editors. The software supports over 80 image formats natively including JPEG, PNG, GIF, BMP, TIFF, PSD, RAW files from hundreds of camera models, plus dozens of esoteric formats through optional plugins. Beyond viewing, IrfanView offers practical editing including crop, resize, rotate, color correction, red-eye removal, sharpen/blur filters, and dozens of effects—all accessible through intuitive interface without layers or complexity that intimidate casual users. Batch conversion processes hundreds of images automatically, applying watermarks, resizing, format changes, or renaming en masse. For photographers organizing shoots, web developers optimizing images, or anyone viewing pictures regularly, IrfanView provides professional tools in lightweight, approachable package.

Beyond core viewing and editing, IrfanView includes slideshow functionality with customizable transitions, basic paint tools for annotations and corrections, EXIF data viewing and editing, thumbnail generation and browsing, screen capture, multi-page TIFF and PDF creation, email integration, and extensive plugin system adding format support and effects. The software’s keyboard-friendly design enables browsing entire folders with arrow keys, applying edits with shortcuts, and working efficiently without constant mouse clicking. For Windows users who’ve tried Windows Photos and found it limiting, or opened Photoshop for simple tasks and felt overwhelmed, IrfanView delivers the perfect middle ground—powerful enough for serious work, simple enough for immediate productivity, and free enough to install everywhere without concern.

Frequently Asked Questions

Is IrfanView really free?

IrfanView is free for private, non-commercial use without limitations. Educational institutions and non-profit organizations can also use it free. Commercial users (businesses, government agencies) must purchase license at €12 ($13) per installation. The free version has no ads, nag screens, or feature restrictions for personal use. This model has worked successfully for nearly 30 years, making IrfanView genuinely free for home users.

Can IrfanView replace Photoshop for basic editing?

For basic tasks like crop, resize, rotate, color adjustment, and simple filters, IrfanView handles most casual editing needs without Photoshop’s complexity. However, it lacks layers, selection tools, advanced compositing, and professional retouching features. IrfanView works perfectly for quick edits, batch processing, and format conversion. For serious photo manipulation or graphic design, use GIMP (free) or Photoshop. Most users find IrfanView handles 80% of their image needs, reserving heavier editors for occasional complex tasks.

Should I install the plugins package?

Yes, install the plugins package for comprehensive format support. While IrfanView handles common formats (JPEG, PNG, GIF, BMP) natively, plugins add support for RAW files, PSD, medical imaging formats, and dozens of others. Plugins also add effects, batch watermarking, and additional features. The plugins download is separate to keep core IrfanView small, but installing both provides the complete experience most users want.

How do I make IrfanView my default image viewer?

In IrfanView, go to Options > Properties/Settings > Extensions tab. Check boxes next to image formats you want IrfanView to open by default, then click “Set selected extensions” button. Alternatively, right-click any image file in Windows Explorer, select “Open with > Choose another app,” select IrfanView, and check “Always use this app.” For thumbnail integration in Windows Explorer, consider using IrfanView’s shell extension plugin.
