The project's current name "Krita" has multi-cultural references. In Swedish, krita means "crayon" and rita means "to draw". In the ancient Indian epic Mahabharata, the name "krita" is used in a context where it can be translated into "perfect".
Early development of the project can be tracked back to 1998 when Matthias Ettrich, founder of KDE showcased a Qt GUI hack for GIMP on Linux Kongress. The idea of building a Qt-based image editor was later passed to KImage, maintained by Michael Koch, as a part of KOffice suite. In 1999, Matthias Elter proposed the idea of building the software using Corba around ImageMagick. To avoid existing trademarks on the market, the project underwent numerous name changes: KImageShop, Krayon, until it was finally settled with "Krita" in 2002. The first public version of Krita was released with KOffice 1.4 in 2004. In years between 2004 and 2009, Krita had been developed as a generic image manipulation software like Photoshop and GIMP.
Change of direction happened to the project in 2009, with a new goal of becoming a digital painting software like Corel Painter and SAI. Also from that point, the project began to experiment with various ways of funding its development, including Google Summer of Code and funded jobs for students. As a result, the development gained speed and resulted in better performance and stability.
The Krita Foundation was created in 2013 to provide support for Krita's development. It collaborated with Intel to create Krita Sketch as a marketing campaign and Krita Studio with KO GmbH as commercially supported version for movie and VFX studios. Kickstarter campaigns have been used to crowdfund Krita's development since 2014.

Design and featuresEdit
The current version of Krita is developed with Qt 5 and KDE Frameworks 5. It is designed primarily for concept artists, illustrators, matte and texture artists, and the VFX industry. It has the following key features:
User experience designEdit
The most prominent feature of Krita is arguably its UX design with graphics tablet users in mind. It uses a combination of pen buttons, keyboard modifiers and an icon-based HUD to ensure frequently-used functions can be accessed by fewer clicks, without the need to search through text-based menus.
Most-used drawing commands can be blindly accessed by a few combinations of 2 keyboard modifiers with 2 pen/mouse buttons:
|Brush size +/-||Shift + Pen drag|
|Pick color||Ctrl + Pen tap|
|Pan||Pen button + Pen move|
|Zoom||Ctrl + Pen button + Pen move|
|Rotate||Shift + Pen button + Pen move|
Pop-up Palette is Krita's right click HUD. It enables instant access to the following functions:
|10 loaded brush presets||Color ring selector||Zoom|
|Load other preset groups||FG/BG color display||Rotate|
|Brush size, opacity, flow, spacing, angle||Recent color||Mirror|
Krita's core digital painting tools includes:
|Brush||Drawing assistants||Selection tools||Transformation tools|
|Graphics tablet support||Adjustable interference intensity||Rectangle||Free position|
|9 different brush engines||Infinite and parallel straight rulers||Ellipse||Rotate|
|Modelled after real tools||Splines (curves)||Freehand (lasso)||Scale|
|Remembers settings for each physical pen||Perspective||Outline||Perspective|
|Pen stabilizer||Vanishing point||Fill||Wrap|
|Multibrush painting support||Fish-eye point||Color||Cage|
Krita's animation tools is designed for frame-by-frame raster animation. It has the following features:
|Similar interface of Adobe Flash||Batch import of frames||Render with ffmpeg|
|Timeline controls||Output to individual frames|
|Realtime animation playback controls||Output to GIF, AVI, MP4, etc.|
Krita uses vector tools for non-destructive editing of the following objects:
- Text (artistic, multiline, calligraphy)
- Vector art
- Fill and gradient
Layers and masksEdit
Krita's layer and mask features includes:
|Layer management||Mask applies to||Non-destructive layers||Non-destructive masks|
|Multiple level layer groups||Raster layers||Clone layers||Transparency masks|
|Select multiple layers||Vector layers||Filter layers||Filter masks|
|Drag-and-drop layers||Layer groups||Fill layers||Colorize masks|
|Layer highlighting||Non-destructive layers||File layers||Transform masks|
|Local selection masks|
Krita's resource manager allows each brush or texture preset to be tagged by user and quickly searched, filtered and loaded as a group. A collection of user-made presets can be packaged as "bundles" and loaded as a whole. Krita provides many of such brush set and texture bundles on its official website.
Customizable tool panels are known as Dockers in Krita. Actions include:
- 2 customizable toolbars
- Toggle display of each docker
- Attach any docker to any sides of main window, or detach to float free
- Buttons to collapse/expand each docker panel
- Group dockers by tabs
Workspace profiles allow different UI customizations to be saved for different workflows being loaded instantly.
OpenGL accelerated canvas is used to speedup Krita's performance. It has the following benefits:
- Better-framerate and response time, pen actions can be reflected without delay
- Better-quality, fast and continuous zooming, panning, rotation, wrap-around and mirroring
- Requires a GPU with OpenGL 3.0 support for optimal experience, in case of Intel HD Graphics, it means Ivy Bridge and above.
Full color management is supported in Krita with the following capabilities:
- Assign and convert between color spaces
- Realtime color proofing, including color-blind mode
- Color model supported: RGBA, Gray, CMYKA, Law, YCbCr, XYZ
- Color depth supported: 8-bit integer, 16-bit integer, 16-bit floating point, 32-bit floating point
Krita has a collection of built-in filters and supports G'MIC filters. It has realtime filter preview support.
Filters included in a default installation: levels, color adjustment curves, brightness/contrast curve, desaturate, invert, auto contrast, HSV adjustment, pixelize, raindrops, oil paint, gaussian blur, motion blur, blur, lens blur, color to alpha, color transfer, minimize channel, maximize channel, top/left/bottom/right edge detection, sobel, sharpen, mean removal, unsharp mask, gaussian noise removal, wavelet noise reducer, emboss horizontal only/in all directions/(laplacian)/vertical only/with variable depth/horizontal and vertical, small tiles, round corners, phong bumpmap.
File formats supportedEdit
Krita's native document format is Krita Document (.kra). It can also save to many other file formats including PSD.
|Save to||Krita Document, OpenRaster document, PSD image, PPM, PGM, PBM, PNG, GIF, JPEG-2000, JPEG, BMP Windows, XBM, XPM, TIFF, EXR, PDF, Gimp image, WebP, SCML, ICO, TGA, CSV, QML|
|Import only||ODG draw, Krita Flipbook, Adobe DNG, Camera RAW, PDF, SVG, XML, XCF|
Krita's mascot is Kiki the Cyber Squirrel, a robotic, anthropomorphic squirrel character created by Tyson Tan. The community collectively decided the mascot to be a squirrel because "krita" is also the Albanian word for Squirrel. The first version of Kiki was posted to KDE forum in 2012 and it was used in Krita version 2.6's introduction booklet. Kiki has been used as Krita's startup splash since Krita version 2.8. So far, each new version of Krita came with a new version of Kiki. Kiki has been used for Krita's merchandise shop items and Krita's Steam project artworks.
Krita sprints are events that Krita developers get together for a few days, exchange ideas and do programming face-to-face, in order to speedup development and improve relationships between members.
