A KRA file is most commonly a Krita document file. Krita is a free digital painting and image-editing program used by artists, illustrators, comic creators, concept artists, and designers. The `.kra` format is Krita’s native working file format, which means it is the main editable project file used by Krita. In the same way Photoshop uses `.psd` files and GIMP uses `.xcf` files, Krita uses `.kra` files to save artwork in a form that can be opened and edited again later.
A `.kra` file is different from a normal image file like JPG, PNG, or WebP. A JPG or PNG is usually a finished, exported image, while a KRA file is more like the original master copy of the artwork. It can preserve editable layers, masks, transparency, guides, selections, color profiles, filters, effects, thumbnails, document settings, and other Krita-specific information. This allows the artist to return to the file later and continue editing separate parts of the design instead of working with one flattened image.
For example, a digital drawing saved as a `.kra` file may have one layer for the rough sketch, another layer for clean line art, another for colors, another for shadows, another for highlights, and another for the background. Since those parts remain separate, the artist can change the background, adjust the shadows, recolor an object, hide a sketch layer, move text, or remove an element without damaging the rest of the artwork. If the same artwork were exported as a JPG, most of those parts would be merged into a single flat image, making detailed edits much harder.

If you need to upload the artwork to a website, send it to a client, or use it in an article, it is usually better to export it from Krita as PNG, JPG, WebP, or another common format. PNG is useful when you need high quality or transparency, JPG is good for smaller photo-style images, and WebP is often useful for websites because it can keep file sizes smaller while maintaining good quality.
A KRA file is also somewhat like a ZIP archive internally. Although it appears as one file in Windows, Krita stores several internal files inside it, such as preview images, document information, layer data, color information, and project settings. Because of this ZIP-like structure, you can sometimes make a copy of a `.kra` file, rename the copy from `.kra` to `.zip`, and open it with tools like 7-Zip, WinRAR, or the built-in Windows ZIP viewer. This may let you inspect files such as `preview.png`, `mergedimage.png`, `maindoc.xml`, and `documentinfo.xml`.
This ZIP inspection method is useful only for checking or recovering information, not for normal editing. For example, if Krita cannot open the file, you may still be able to extract `mergedimage.png`, which is a flattened preview of the artwork. However, you should not edit, delete, rename, or rearrange the internal files unless you know exactly what you are doing, because changing the internal structure can corrupt the file and prevent Krita from opening it.
In simple terms, a KRA file is the editable master project file for Krita artwork. It keeps the separate pieces of a design intact so the artist can continue working on them later. For editing, open it in Krita. For normal viewing, sharing, or website use, export it as a standard image format such as PNG, JPG, or WebP.
