**Oojao Image Editor** is a powerful and free photo editor designed for Android devices. It offers a range of cool effects and supports working with multiple projects, tabs, and layers.

To keep the app free, it is ad-supported; however, the ads are non-intrusive and can be quickly closed or temporarily disabled in the Settings. Importantly, no ads appear during editing sessions!

You can perform all standard canvas and layer manipulations, such as resizing, cropping, drawing, erasing, drawing shapes, bucket filling, selecting, copying, pasting, deleting, moving, aligning, rotating, flipping, and more.

Adjust image properties like brightness, contrast, and saturation using filters, or apply effects including sharpening, blurring, bump mapping, adding shadows, and many others. The app supports undo and redo functions, and also allows you to save custom action sets and presets for later reuse.

You can save your work with all layers intact, enabling you to seamlessly resume editing at a later time.
