How many images can I merge?

There is no hard limit, but very large batches (50+ high-resolution images) may take a minute to process. The tool handles each image sequentially in the browser.

What is the difference between Fit and Fill?

Fit scales the image so it fits entirely within the page margins (may leave white space on sides). Fill scales the image so it covers the entire page (may crop the edges).
