Compare many pictures
Add up to 60 pictures or PDF pages of the same place, mark four common points on each, then compare any two, slide through a timeline, find changes and save a PDF, GIF or MP4.
Compare many pictures of the same place or thing, such as satellite images over the years, a building site week by week or a set of scans. Add up to 60 pictures or the pages of a PDF. On each picture mark the same four points, choose 2D (turn and resize) or 3D (also stretch for a different angle) and every picture is lined up on the first one. Then compare any two of them side by side, with a slider, overlapped or with a hold button, slide through all of them on a timeline (the current picture with the next one faintly over it), and find what really changed between neighbours. Save a professional PDF report, a GIF (up to 1200 px) or an MP4 video (up to 1980 px) at 1 to 10 pictures a second with a fade between them. Everything runs on your device, so nothing is uploaded. Free, with no sign-up.
