Free Image Stitching & Panorama Maker

What does the image stitcher do?

The freeimgtool image stitcher merges several photos that share overlapping content into a single seamless image. Use it to build a panorama from horizontal sweep shots, to combine multiple photos of a long whiteboard, or to flatten a large document captured in several frames. Under the hood it runs entirely in your browser: corner detection, patch matching, RANSAC alignment, and feather blending across the seam. Photos need genuine overlap — if it cannot find a confident match it tells you rather than guessing.

Two modes are available. Panorama assumes a rotation around the camera and is the default for outdoor scenes. Flat scan assumes a translation across a flat surface and is the right choice for stitching pages, whiteboards, or maps shot top-down.

How to use it

1. Click the upload box and pick 2 to 4 photos (up to 5 MB each).
2. Re-order the photos with the up/down buttons so they line up left to right or top to bottom.
3. Choose Panorama or Flat scan.
4. Click Stitch.
5. Click Download panorama to save the result.

Tips for a clean stitch

• Aim for 30–50% overlap between neighboring shots.
• Keep exposure and focus consistent between frames.
• Avoid moving subjects in the overlapping area.
• Hold the camera level so the horizon does not jump.
• For flat scans, shoot straight-on, not at an angle.

Who uses it

Travelers turning a sweep of phone photos into a wide landscape. Real estate agents combining wide-angle room shots. Students photographing a long whiteboard or a whole document. Drone hobbyists assembling map tiles. Anyone whose camera could not fit the scene in one frame.
