KRA is the native format of Krita, a free painting app for digital artists. Created and opened by Krita. Krita grew out of the KDE project and is built specifically for digital painting. Krita was originally called KImageShop, then Krayon, before trademark trouble led to the name Krita in 2002. Inside a KRA the layers are stored as XML and PNG data, with a “mimetype” entry reading “application/x-krita”.

How do I open a .KRA file?

Drop a .KRA file onto Analyser at https://lab.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. Open Krita (.kra), Procreate and Paint.NET (.pdn) paintings by showing the flattened preview baked into the file - the full merged image for Krita, the QuickLook thumbnail for Procreate, the embedded PNG preview for Paint.NET - alongside the canvas size, layer count and app version. Their per-layer artwork is in a private format, so the embedded preview is the faithful render.

Can I open a .KRA file online for free?

Yes. Analyser is a free online .KRA opener and viewer that runs entirely in your browser - your .KRA file never leaves your device, so there is nothing to upload and no software to install. It even works offline once installed.
