What is a CPBITMAP file?

A CPBITMAP file is a wallpaper or lock screen image used by an iOS device, such as an iPhone or iPad. It is saved in a proprietary format used only by iOS. As such, image viewers and editors cannot open CPBITMAP files.

More Information

When you set an image as your iOS wallpaper or lock screen, the operating system creates a copy of that image and converts it to the CPBITMAP format. This allows iOS to load the image more efficiently at startup and whenever you view your home or lock screen.

Common CPBITMAP Filenames

HomeBackground.cpbitmap - The name iOS assigns to your wallpaper image.

LockBackground.cpbitmap - The name iOS assigns to your lock screen image.

How to open a CPBITMAP file

No image viewer or editor can open CPBITMAP files. However, you can use the utilities listed below to convert CPBITMAP files to the .PNG or .JPG format.

How to convert a CPBITMAP file
