Photo Blender is a multimedia application designed for iPhone users, allowing them to seamlessly blend multiple images into one stunning montage. With support for up to 16 photos, users can choose to join images either vertically, horizontally, or in 2D formats. The app features a comprehensive image editor that enables users to enhance individual photos or the entire blend, applying filters, rotations, and custom text to create unique visuals.

The application supports four blend types: horizontal, vertical, 4-square, and 9-square blends. Users can utilize their device's camera to capture images directly within the app, or select from their Photos library. The blending margin width is adjustable, allowing for both smooth transitions and edge-joined effects. Additionally, users can save their blends in a dedicated gallery for easy access and sharing via email or messages.
