Frequently asked questions
How many images can I combine?
Up to 30 at a time. The result is limited to 8000 px on its longest side; larger layouts are scaled down.
How do I make a before/after image?
Add both images, choose Side by side, keep “Match image sizes” on, and combine.
Can I change the order?
Yes. Use the up and down arrows next to each image.
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.
