This isn’t new software by any means, but there’s a reason it’s reached such venerable standing: IrfanView is one of the best bits of free software of its kind. If you want to view an image quickly and easily, you want IrfanView. It supports a long list of formats, including obscure image types from old cameras, vector graphics, and more. Viewing isn’t its only trick: converting images from one form to another is supported, and you’ll be able to perform rudimentary tweaks too.
It’s quick to launch – in our experience far faster than Windows 10’s lesscompatible Photos app – and you can even extend its capabilities. Head to www.irfanview.com/plugins.htm to add support for audio and video files and even PDFs. Set it as the default app for images: in Windows 10, open Control Panel and head to Default Programs to do it.
See it IrfanView supports a huge range of image formats, and is faster than Photos.
