Frequently asked questions
Is there a limit on how many files I can join?
There is no fixed limit, but very large files use your device's memory. If the browser slows down, merge in smaller groups and then merge the results.
The merged file is too big for the portal. What now?
Run the result through the PDF Compressor. It re-compresses the photos inside scanned pages, which is where most of the size comes from.
