Image stitching FAQ
Are source images uploaded?
No. Reading, decoding, layout, and export happen in your browser. Source images and results are not uploaded to RouteMarket.
How many images can I stitch?
You can currently add up to 20 images. Very large compositions are scaled down automatically to stay within browser canvas limits.
How do the four layouts differ?
Vertical layouts share a width, horizontal layouts share a height, grids use regular cells, and free layout lets you move, resize, and layer images on a fixed canvas.
Should I export PNG, JPEG, or WebP?
Choose PNG for lossless detail, JPEG for photographs and broad compatibility, or WebP for a strong balance of quality and file size.
