Where does "just change the extension to .png" fit in this chart?

Tell the Rabbit AI landwaste thingy to describe the image, then feed the result into Midjourney.
Rename file extension to .png
Works every time for *.webp .
Where is "changing the file type extension" in the name?
That has to be Chaotic Evil.
that would be renaming the file extension but keeping the same format opening it up in an app that breaks it totally, then saving that and sharing it with a Windows user and spending an hour with them trying to make it work because they have to see it!!!!!
You'll quickly learn which software trusts extensions and which uses MIME type detection
You know who used to do that? Microsoft Teams. I would take photos with my phone and upload them via Teams, Teams would display them just fine but saving them teams would name them .png (even though they were jpeg) and I couldn't open them with the gnome image viewer (this is also how I found out that the image viewer prioritizes extension over magic byte (which seems stupid to me).
That's not on the chart because it doesn't convert it. It only renames it. A JPEG ending with .png is still a JPEG
That's what the mimetype cult wants you to believe.

Why is ffmpeg Chaotic? I use it for video edits sometimes, too. Like if you need to stack videos in rows and columns, FFMPEG is my go-to.
Using the video tool for a single still image is a bit chaotic, but it's still a tool made for the job so it's good. Chaotic Good. Makes sense to me.
It's a hugely powerful tool.
However, as we all know, some people treat the terminal as if it is the very inky blackness, in which, writhes the tentacles of C'thulu itself.
what about recreating the image pixel by pixel from scratch?
You'd first have to destroy and re-create the universe. So probably evil.

Mint has an "Action" for that, what does that make me? 
actually lawful good, imagemagick and ffmpeg barely do anything different in this case, and the python script uses imagemagick if I know PIL right
Damn, that's really handy. I would kill for Dolphin to have this.

What's always missing is nomacs - the best image viewing and light editing toolkit app on linux.
Nobody ever mentions it. Why is that? Why? It supports all the formats. It has the best slideshow options. The UI is as minimal or as informative as you set it to be. WHYYYYYY DOES NOBODY TALK ABOUT IT??? Who paid you to be silenced?
(and yes, it can convert the formats)
https://github.com/nomacs/nomacs
I used it for a long time years ago and it is indeed very great. But its only maintainer stopped around 2021/2022 because he got a new job or something along that line. As far i see he partially returned later but is still looking for more contributors. so the future of the project is not really secure. e.g. see https://github.com/nomacs/nomacs/issues/987
So more eyes on Nomacs would be indeed good.
It's so crazy to me that guy was unemployed and is spending his days making a high quality software product for free

Doesn't really seem like the sort of thing that needs regular updates though. Should keep working fine while Qt6 is available.
This sounds pretty sweet and it's indeed the first time I've ever heard about it so... keep spreading that word brother???
It reminds me of IrfanView, but I'm sure it's better than that

I use imagemagick, but the commands changed recently and I don't use it often enough to remember the new ones.

Decode the image with ffmpeg, pipe it to imagemagick and encode it again
I needed to crop a couple of images a few days ago and completely forgot about graphical editors. I spent like 10 minutes repeatedly using imagemagick with slightly tweaked parameters until I liked the crop
I needed to do the same, but for 6500 images. Worked out great.
Whatβs it called if youβve done all of these?

Never asked chatgpt, or the camera.
But otherwise, yahtzee.

It's missing the "take a screenshot on your mobile phone" (which drives me nuts when people do this instead of sending me the link or the original photo).

I assume bash scripts using jpegtopnm | pnmtopng are also in the neutral good category (from Netpbm).
