You. Your favorite place. In the same photo — without ever being there. BlendPic blends two images together with pixel-perfect control. AI background removal does the hard part automatically. Double exposure art, dreamy composites, impossible selfies — the only limit is your imagination. "How to Use This App" You can easily create photos in the following 3 steps: (1) Select two photos. The image selected with the left icon will be placed on top, and the image selected with the right icon will be placed on the bottom. You can also use photos prepared in advance by the app. (2) Touch the photo to erase the top image and reveal the bottom image. You can also change the transparency of the top image with the slider. (3) Once completed, you can share the created photo using LINE, X (formerly Twitter), Facebook, and more. ・Undo/Redo You can undo or redo your edits at any time (up to 20 steps). ・AI Background Removal Automatically remove the background from a photo using AI (Vision Framework), making it easy to composite subjects onto new backgrounds. ・Trimming Crop and adjust your images to the perfect composition.
