Where IrfanView fits
Use it when quick inspection and straightforward conversions matter more than a full design suite.
Check before you choose
Check plugin sources and the usage license that applies to your work setting.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
The right workflow starts with the type of asset you need. RAW development, vector illustration, layered image editing and 3D modeling each have different file and hardware requirements.
