Inkscape
The professional, open-source vector graphics editor for limitless creative freedom.
A free, easy-to-use, and lightweight raster image editor for quick adjustments and creative drawing.
KolourPaint is a free, open-source raster graphics editor developed by the KDE community, primarily targeting the Linux desktop ecosystem but maintaining cross-platform compatibility through the KDE on Windows initiative. Built on the Qt framework and leveraging KDE Frameworks 6 by 2026 standards, it provides a streamlined interface designed for tasks that require immediate execution without the overhead of professional-grade suites like GIMP or Photoshop. Its technical architecture focuses on efficiency, a low memory footprint, and high-performance pixel manipulation. In the 2026 landscape, while AI-driven generative editors dominate high-end creative workflows, KolourPaint retains high utility for manual pixel-perfect editing, diagram annotation, and basic photo retouching where data privacy, local processing, and simplicity are paramount. It serves as a spiritual successor to classic Paint-style applications but offers significantly more robust capabilities, including alpha channel (transparency) support, basic color balance adjustments, and a wide array of selection tools. As a KPart-based application, it integrates seamlessly into the Linux file management ecosystem, making it the default choice for millions of users requiring a 'no-friction' entry point for visual editing tasks.
Supports full transparency for formats like PNG, allowing users to define transparent pixels via the color similarity tool.
The professional, open-source vector graphics editor for limitless creative freedom.
The professional-grade creative suite for high-fidelity generative image design using Stable Diffusion.
Realistic procedural graphic effects for high-precision design workflows.
Professional-grade Text-to-SVG and Raster-to-Vector generation powered by semantic path-tracing AI.
Verified feedback from the global deployment network.

Uses KDE Input/Output (KIO) for network transparency, allowing files to be opened/saved over SSH, FTP, or SMB directly.
Includes rectangular, elliptical, and free-form selections with 'Opaque' or 'Transparent' selection backgrounds.
A threshold-based fill and selection algorithm that allows users to select regions with similar but not identical color values.
Algorithmically detects the bounding box of the non-background pixels and crops the image to those dimensions.
Native integration with SANE (Scanner Access Now Easy) to acquire images directly from hardware.
Leverages the QImage framework to support over 40 distinct image formats including legacy types like PCX.
