FAQ
How do I put two pictures side by side?
Add both, choose “Side by side” and “Same height”, then “Download the merged image”.
What does “Same height” do?
Taller images are scaled down to the shortest one so they line up, without enlarging any image. “Original sizes” keeps each image as it is and fills the gaps with the background color.
Is quality lost?
At original sizes the pixels are copied as they are. When scaling to match, the browser’s highest quality is used. Choose PNG for lossless saving.
Can I combine images into a PDF instead?
Yes, with Image to PDF: each image becomes a page.
Are my images uploaded?
No. Everything runs inside your browser; the images never leave your device.
