- 2Set the direction, gap and background; grid mode also supports column count.

Zero-upload privacy
Original images, Canvas data and the PNG Blob stay on this device and are not uploaded.
Images are not sent to external servers; speed depends on device performance and browser support.
Frequently asked questions
How many images can I merge?
The practical limit depends on browser memory and Canvas dimensions; test with reasonable sizes first.
Does grid mode crop images?
No. Images are centered inside each cell with their ratio preserved; the selected background fills empty space.
Is the output lossless?
PNG uses lossless pixel encoding, although very large images may hit browser Canvas limits.
