Krita is not trying to be a general-purpose photo editor that happens to include brushes. It is designed around digital painting, illustration, and drawing workflows, which makes it immediately more interesting for artists who care about canvas feel, brush control, layers, and sketch-to-finish creation instead of basic image correction alone.
It is especially suitable for illustrators, hobby artists, comic creators, concept designers, and students who want to work with a pen tablet or stylus on Windows. If the goal is to draw, paint, ink, color, or build artwork from a blank canvas, Krita makes more sense than forcing a photo-first tool into a painting role.
What makes Krita worth keeping is the clarity of its purpose. Brush engines, layer tools, painting-oriented workflow, and support for long-form creative sessions give it a level of seriousness that many free art programs never reach. For artists who want to build a repeatable desktop drawing workflow, that matters far more than flashy marketing.
The tradeoff is that Krita asks you to learn a proper creative workspace. If you only need to crop screenshots or add text to images, it will feel too heavy. It also rewards users who organize files, brushes, and export formats carefully instead of expecting instant beginner simplicity.
My recommendation is to use Krita when your work is genuinely painting or illustration centered and you want a capable Windows desktop tool built for that kind of making. Start with a few dependable brushes, keep your document sizes realistic, and let the software grow with your art practice instead of trying to master every panel on day one.
