About this format
KRA format context
Format: KRA
Overview
KRA matters because digital painting workflows need a native format that preserves layers, masks, color management choices, and editor-specific features instead of flattening everything into a delivery image too early.
Painting and illustration tools needed a native editable format that could preserve rich working state across sessions.
KRA is important inside Krita-centered illustration, concept-art, and painting workflows and usually gets converted only when work is ready for delivery or exchange.
KRA is closely associated with Krita / KDE community.
KRA is usually selected for workflows that center on capture ingest, editing, web or print delivery.
Typical Workflows
- capture ingest
- editing
- web or print delivery
Common Software
- Krita
- digital painting workflows
Strengths
- Preserves editor-specific layered working state.
- Useful for long-running painting and illustration projects.
Limitations
- Not a cross-tool final-delivery format.
- Conversion to flatter outputs can discard the editable state users actually care about.
Related Formats
- ORA
- PSD
- XCF

KRA belongs to Krita-based concept art, illustration, comics, matte painting, and digital painting workflows.
It is strongest in open-source art pipelines and among creators who need a native Krita document for ongoing editing.
Status: proprietary. Introduced: 2005. Invented by: Krita / KDE community. Stewarded by: Krita / KDE community.
How KRA fits into workflows
