Frame your photos in your browser. Upload a photo, a scan of several photos, or a PDF: it finds each photo, straightens it and removes the white space. Wrap fits the frame around your photo at full size; Crop fits it into the frame. Caption each photo (the same words or a different line on each), and straighten any one by hand. Nothing is uploaded.
Swap the Vintage frame for your own image. Best with a PNG that has a transparent window where the photo goes (a solid black window also works). The window is detected automatically and it works in Wrap and Crop.
