Frequently asked questions
What does "Match heights" do?
For side-by-side merges, every image is scaled to the height of the shortest one so the row lines up neatly. For stacked merges, widths are matched instead.
How does the grid option size images?
Each cell is as large as the smallest image, and each picture is fitted inside its cell without stretching, centered on the background color.
Is there a size limit?
The merged picture must stay under about 100 megapixels, the practical limit for browser canvases. The tool tells you if the result would be too large.
In what order are images placed?
In the order the files were selected. Rename or select them in the order you want if needed.
Are my photos uploaded?
No. They are combined on a canvas in your browser.
