IrfanView

I've been using IrfanView since at least 1997, if not earlier in 1996.

I still use IrfanView to this day. It's my Swiss knife for a lot of simple photo editing work (cropping, resizing, padding, text-adding, etc), batch-processing, and for browsing single photos through directories.

It's not just good, it's way faster than the bloated alternatives.

To top it off, IrfanView works beautifully on my Linux via Wine, and also on my Mac M1/M2 machines (and as a tool quicker than even Mac's own Preview). It's a primary install for me, whichever any platform I'm working on; and a software that's truly a gift to the world.

How do you get it on macOS?

If it's for non-commercial use, you might find this a spritual equivalent, cross-platform:

This comment is baffling. Just so you know, the IrfanView license requires commercial users to pay for a license, just like XnView does. Apparently that's... bad?

also allowed in commercial settings (BSD style license):

open-source, ignore the simple web page, software is awesome.
