Frequently asked questions
How many images can I combine?
Up to 30, within your device's memory.
Do images need to be the same size?
No. Heights (or widths) are matched automatically.
Is this the same as the Image Merger?
Yes, it uses the same engine — this page is set up for quick side-by-side combinations.
Are my images uploaded to a server?
No. Files are decoded, processed and re-encoded by your browser using the canvas API and Web Workers. Nothing is sent to any server, and there is no account or storage. Closing the tab discards everything.
