Put several pictures together into one file — stacked or side by side, with as much space between them as you like.
Drop in two or more. They are joined in the order you add them.
Stacked or side by side, then set the spacing and the background colour.
You get one new picture. The originals are untouched.
The most common reason to join pictures is comparison — a before and a after, two options side by side, a set of screenshots that only makes sense together. Side by side suits a comparison; stacked suits a sequence someone will scroll through.
Images of different sizes are scaled to match on the joining edge, so nothing is stretched out of shape and nothing is enlarged past its real detail.
If you are joining photographed documents rather than pictures, the image to PDF tool is usually the better one — it keeps each page separate and produces a file people can print.
No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.
None set by us. Very large files are limited only by your device's memory, and we warn you before that becomes a problem.
No, and there is no daily limit either. There is nothing to sign up for.
Images are joined in the order you add them, so add them in the order you want, or start over and re-add.
They are scaled to match on the edge being joined. Nothing is stretched or enlarged.
