Merging PDF documents is one of our most popular tools. You know it! So much that over 18 million people use Smallpdf on a monthly basis to convert their documents. On top of merging files into a single PDF document, why not: Our web pages also offer quite a few other tools for you to work with, for free. Upload a single document or multiple PDF files into the toolbox (you can drag and drop) > rearrange files or pages positions > Hit 'Merge PDF!'.
