Step-by-step installation (Windows)
1) Download the installer
- Go to the official IrfanView download page and choose the correct Windows installer (32-bit or 64-bit, if offered).
- Download the file to your PC (for example, your Downloads folder).
2) Run the installer
- Double-click the downloaded installer file.
- If Windows SmartScreen or User Account Control appears, confirm that you trust the source and proceed.
- Follow the on-screen prompts (typically Next -> Next -> Install).
3) Finish and launch
- When installation completes, click Finish.
- Open IrfanView from the Start Menu.
Recommended options during/after install
- Install plugins (optional but recommended): Plugins add support for more image formats and features.
- Set file associations: You can choose which image types open with IrfanView.
- Check updates: If IrfanView offers an update prompt, install it for security and compatibility.
Verify it works
Open IrfanView and test with a common image file (like JPG or PNG). If the file opens correctly, try a less common format (like WEBP) to confirm whether plugins are needed.
Common troubleshooting
- Installer won’t run: Re-download the installer and ensure you have permission to install software.
- Images don’t open certain formats: Install the IrfanView plugins or check the supported formats list.
- Default app not set: In Windows Settings > Apps > Default apps, set IrfanView for image file types.
Quick checklist
- Download from the official IrfanView website.
- Run the installer and complete setup.
- Optionally install plugins for more formats.
- Test with a JPG/PNG and confirm file associations.
