XCF is GIMP’s native project format, intended to keep editable image information such as layers. Make GIMP the opener when XCF files are captured by another app; exporting a flattened image is a separate task.
Method 1: Use Finder
- In Finder, select a sample file such as artwork.xcf.
- Press Command–I, or choose File → Get Info.
- Expand Open with and choose GIMP. If it is missing, choose Other and locate the installed app.
- Click Change All and confirm the macOS prompt.
- Double-click another file of the same type to check the new default.
Method 2: Manage associations with Pahkui
Pahkui lets you browse by app or by format. When setting up an editor for several file types, you can inspect the current defaults and review pending changes in one window. Requires macOS 14 or later.
- Open Pahkui, switch to Format, and search for the extension you need from .xcf.
- Select GIMP. Use Choose another app if it is not listed.
- Review the pending association, click Apply changes, and confirm the new app in the macOS dialog.
The formats in this guide require Pahkui Pro, a one-time purchase for lifetime use. The manual Finder method does not require a purchase. See pricing

If the default app does not change
- If a newer XCF does not open in an older GIMP version, check version compatibility instead of renaming the file.
- To share a viewable image, export an appropriate image format while retaining the XCF project.
- If GIMP is missing, confirm it is installed and can open the sample directly, then locate it with Other. If an extension is absent from the catalog, add the format in Pahkui. Changing an association does not add format support to the target app.
Common questions
Can I rename XCF to PNG?
Renaming is not conversion. Export from GIMP when you need PNG, JPEG or another image format.
How do I restore the previous app for .xcf?
Choose the previous app again in Finder or Pahkui and confirm the change. This updates the type association without deleting files. Use the Open With context menu for a one-time exception.
