Panorama Maker Online — Free, No Signup
Join 2 to 4 photos into one image. Useful for a wide scene shot in pieces, a long document captured in sections, or any set of images you want side by side in a single file.
How to do it
- Drop all your overlapping photos in at once, in order.
- Make sure neighbouring shots share roughly 30% overlap, or the seams will not line up.
- Let the stitcher blend them into one wide image.
- Download the panorama.
What it joins and how
The tool takes between two and four images and composes them into a single output. Each input is scaled to a 1600-pixel long edge before composition, which keeps the whole operation inside a browser tab's memory budget while staying well above what any screen displays. The result downloads as one image. This is a compositional stitch rather than a feature-matched panorama build — it places your images together predictably rather than attempting to detect and align overlapping content between them.
Shooting for a good result
Keep the camera at a consistent height and rotate around yourself rather than walking sideways, which changes the perspective between frames and makes the seams obvious. Lock exposure if your camera allows it — the most visible flaw in an amateur panorama is not misalignment but a brightness step where one frame was exposed for sky and the next for ground. Overlap adjacent frames by roughly a third. Avoid subjects close to the lens, since near objects shift position dramatically between frames in a way distant ones do not.
Uses beyond landscapes
The obvious case is a wide view too big for one frame. Less obvious ones are more common in practice: a long receipt or contract photographed in overlapping sections, a whiteboard captured in halves because standing far enough back made the writing illegible, before-and-after comparisons placed side by side for a report, and product shots from several angles combined into one image for a listing. Anything you would otherwise attach as three separate files often reads better as one.
Why four images and not twenty
Every input is decoded and held in memory at once, and browser tabs have a real ceiling on that. Four images at 1600 pixels each is a limit chosen so the operation completes reliably on a mid-range phone rather than failing halfway through on anything but a desktop. If you need a longer sequence, stitch in stages: combine the first group, then combine that result with the next. The output of one run is a valid input to the next.
Limits
Between 2 and 4 images per run, each up to 5 MB, each scaled to a 1600-pixel long edge before composition. Output is a single downloadable image with no watermark. Everything runs in your browser — the photos are never uploaded, which is worth noting given how often the thing being stitched is a document rather than a landscape.
Frequently asked questions
How many photos can I stitch at once?
Between 2 and 4 per run. Every input is held in memory simultaneously, and four is the limit that completes reliably on a mid-range phone.
Can I stitch more than four?
In stages. Combine the first group, then feed that result back in with the next images. The output of one run is a valid input to the next.
Why is there a visible brightness step between frames?
The frames were exposed differently. Lock exposure before shooting a sequence — uneven exposure is more noticeable than slight misalignment.
Does it detect and align overlapping content automatically?
No. It composes your images together predictably rather than feature-matching between them, so shoot with consistent framing.
What resolution is the output?
Each input is scaled to a 1600-pixel long edge before composition, so the combined image is proportionally larger along the joining axis.
Are my photos uploaded?
No. Composition happens in your browser, which matters given how often people stitch documents and whiteboards rather than landscapes.
