🌆Panorama Stitcher Online - Merge Photos into a Panorama

Your phone’s panorama mode fails the moment you wobble, but a handful of overlapping shots taken one after another can still become a wide panorama — and this tool stitches them right in your browser. It finds hundreds of corner features in each photo and computes binary descriptors, matches them between every pair of photos, rejects false matches with RANSAC and works out how the shots fit together, detecting the left-to-right order automatically, so the order you add them doesn’t matter. With three or more photos it switches to a cylindrical projection with a focal length estimated from the alignment, so the ends don’t stretch. Exposure compensation evens out brightness and colour casts between shots, multi-band blending hides the seams, and auto-crop trims the result to the largest clean rectangle. Matching runs on downscaled copies while warping and blending use the full resolution, all in a background thread you can cancel at any time.

FAQ

It says no overlap was found — what now?
Neighbouring photos should overlap by 30–50% and the shared area needs detail such as buildings, trees or text; plain sky, blank walls and water are hard to match. If automatic detection still fails, drag the list into left-to-right order and choose Use list order.
Planar or cylindrical projection?
Use planar for 2–3 shots with a narrow view or flat subjects such as walls and whiteboards — straight lines stay straight. Use cylindrical for wide landscapes shot by turning on the spot, so the edges don’t stretch. Auto picks cylindrical for three or more photos.
Why are there ghosts or misalignments at the seams?
Usually the camera moved sideways between shots (parallax) or people and cars moved. Rotate around the phone rather than walking, keep it level and avoid moving subjects; multi-band blending also smooths the transitions.
Are my photos uploaded? Is it free?
