remove backgrounds? i think you could find a krita plugin for it, or just use an online website / huggingface space.

I use Krita every time i need to edit something. It’s more than good enough for me

Lots of great suggestions here already

I haven't seen mobile editing mentioned yet:

• ImageToolbox for a very good Android image editing tool

• Fossify Gallery for some quick editing tools built into the gallery

• While not directly for editing, Tidy on android allows for AI search locally

• Termux for any CLI edits (imagemagick, etc.)

I often use imagemagick (cli) for cropping, rotating, resizing, etc.

I heard about Graphite the other day. It’s nowhere near finished, but very promising. Hopefully, it becomes the FOSS of Photopea. https://editor.graphite.rs/

Krita, I use it for everything, I hate gimp, it feels so bad

You can install and run Stable Diffusion locally (Pinokio is a versatile installer that can run SD and many other open-source AI tools as well). With SD you can build your own upscalers that are better than Upscayl, and do things like background removal too (in addition to prompt-based generation and such).

I have used darktable, but doesn't seem to fill your need as it is more a lightroom replacement than Photoshop https://www.darktable.org/

Pinta.

It's like a Linux version of Paint.net

GIMP for most general stuff, Krita for painting and 2D animation, Aseprite for pixel everything.

I've been meaning to get into some image generation type things too. The best self hosted tool I know of is InvokeAI. I'm sure there could be a whole other post (or other community) about image generation tools.

Darktable for raw image processing

I paid 700 for Adobe Photoshop each month, and pay extra 10 each time to unlock when I open the program.

I use Gthumb for simple edits (croping, resizing, rotating...).

With ChaiNNer you can remove background, upscale (local), it's a lot more flexible and compatible with models than Upscayl, also a little bit more complex (node based, not as complex as comfyUI). You can upscale an image with a face model and use other model for everything else in the same image.

A very useful tip for technical images (i.e., lab report/research): export whatever graph you created as .svg, and do some prettifying touches in InkScape. It is faaaar easier than doing it in code.

Also, always export the .svg, even if you're not gonna use it. You never know when you want to do a very small correction, and it will save you quite some time.

I used to use GIMP, but Krita has gotten advanced enough to where it can replace it for most things (at least that I would use it for).

dd if=/dev/zero of=image.png bs=1k count=1024 conv=notrunc

My daughter and my sister 🤣🤣. I have 0 art in my body, so they do all that for me. I could say I have a great AI driven FOSS process in place, lol.

Image removal and AI tools have an overlap, for sure. RemBG is pretty effective, which runs in many of the environments with Stable Diffusion. Bria is a recent improved model for RemBG, which I've had some good success with. It's not perfect, but it cuts out a lot of the work.

I use kolourpaint to make memes

I like MyPaint even though development seems dead (there hasn't been a new release in four years). I specifically like the infinite canvas when I'm working on the initial sketches. I switch to Krita when I'm ready for the final line art.

Image is a broad word. I would say in order of usage per year it would be Darktable, Inkscape, Hugin, GIMP, Krita… but these obviously serve different purposes.

I'm not an artist, I just need the occasional hack job or screenshot annotation.

I loved the simple programs (this love stems from all the way back to MacPaint v1.0) and MS Paint has largely been ok for me apart from its lack of png support and only 90° rotations.

On Linux, Pinta has been fantastic but these last few years it got increasingly more crashy, to the point where it will now consistently crash within 10 seconds or two clicks, regardless of Linux distro / laptop/pc / version of Pinta. (insert "whyyyyy" meme here)

I've tried Krita, but it's simply too much. Don't even want to try installing Gimp. I am sad.
