Seamline Panorama Stitcher

About: Seamline Panorama Stitcher

Seamline turns overlapping photos into seamless, gigapixel panoramas, entirely on your iPhone or iPad.

ONE FLAT PRICE
Pay once for the full app. No subscriptions. No in-app purchases.

It is built for drone pilots and landscape photographers. Seamline reads the gimbal angles your drone records in every photo, works out the rows and capture order by itself, and aligns every frame to a fraction of a pixel on the original, full-resolution images. Panoramas shot on a phone or camera work too.

FULLY AUTOMATIC
• Rows, capture order, lens distortion and exposure are worked out for you
• Featureless sky frames are placed using the drone's orientation data
• Photos that don't belong (another flight, camera or zoom) are left out, and Seamline tells you why
• Grid Assist for difficult sets: describe the rows and shooting order

SEAMLESS RESULTS
• Sub-pixel alignment on the original pixels
• Exposure, color and vignetting matched across every frame
• Seams that route around moving clouds and other motion
• Natural tone mapping that keeps detail in the sun and in the shadows

GIGAPIXEL AND LOSSLESS
• Full-resolution TIFF, 16-bit or 8-bit, lossless (BigTIFF beyond 4 GB), ready for Photoshop, Lightroom or Affinity Photo
• JPEG up to 65,500 pixels wide, plus PNG and HEIC, saved straight to your photo library
• Inspect any part of the panorama at 100% before you export

PRIVATE BY DESIGN
• Everything runs on your device: no account, no uploads, no tracking
• On iOS 26 and later, Seamline keeps working while your phone is locked
• Reopen any project instantly to adjust it or export again

Try it in seconds with the built-in sample: a four-row drone sunset panorama.

Works with DJI drone panoramas, including multi-row and telephoto captures, and with overlapping photos from iPhone and most cameras.
