PDF Merger vs PDF Splitter — What's the Difference?
The short answer: PDF Merger combines: it joins 2–12 PDFs into one file in the order you choose, up to 50 MB and 500 pages combined. PDF Splitter divides: it pulls selected pages or ranges out of one PDF into a new file, leaving the original untouched. Many documents into one, versus one document reduced to what you need.

Frequently asked questions
What's the difference between PDF Merger and PDF Splitter?
The merger validates and combines 2 to 12 PDFs — up to 50 MB and 500 pages in total — into a single document you can reorder before downloading. The splitter reads one PDF and writes a new one with just the pages or ranges you select; the original file is never modified. Both run in the browser.
Can I use PDF Merger and PDF Splitter together?
Yes — they cover both halves of reorganizing a document set: split the pages you actually need out of each source, then merge the results into one final PDF.
