What Krita does
Krita 5.3.3 is KDE's GPL-licensed painting application for Windows, macOS, and Linux. This record now identifies the publisher's Windows x64 installer and portable ZIP, signed macOS DMG, and Linux x86-64 AppImage instead of linking only to a directory. The release provides no 32-bit Windows build; its published requirements start at Windows 8.1 and macOS 10.15.
Krita's brush engines, layers, masks, animation workspace, and tablet input are aimed at illustration and painting. Tablet pressure, tilt, rotation, and acceleration depend on the tablet, driver, operating system, canvas settings, and brush engine, so support is not a promise that every device exposes every input. Large canvases, animation frames, filters, and high-bit-depth documents can substantially increase memory and scratch-space use.
KRA is the native format. PSD and other imports are interoperability paths, not lossless round-trip guarantees; unsupported Photoshop effects, text, smart objects, color features, or animation data can change. Preserve a KRA master and test representative assets. Python plug-ins execute code and can have version-specific dependencies.
KDE publishes a detached signature for the Linux AppImage and versioned package details in the release directory. This review did not install Krita, verify the detached signature locally, test a tablet, or round-trip PSD files.
