It can convert and process files in batches, rotate and crop JPGs without loss, create slideshows, scan, print, and capture the screen. Editing features include painting tools, effects, watermarking, IPTC editing, and multipage TIFF editing. The maker describes support for many file formats, with plugins adding formats such as AVIF, PDF, SVG, WebP, and camera RAW. Other plugins add OCR, FTP transfer, video playback, Photoshop filters, and PDF support; some require additional software or files. A Shell Extension adds image actions to Windows Explorer and other file managers. IrfanView is listed for Windows XP, Vista, 7, 8, 10, and 11, in 32-bit and 64-bit versions. Private, non-commercial use is free. Commercial use requires a license; the listed single commercial license costs $18 as a one-time purchase and is perpetual. The maker’s privacy policy says the software does not collect or transmit personal data.
