About this tool
Upload two or more PDFs and combine them into one document, in the order you choose.
Frequently asked questions
Does merging affect the quality of my PDFs?
No — merging combines the pages exactly as they are; content quality is fully preserved, nothing is re-compressed or re-rendered.
How many PDFs can I merge at once?
Upload as many as you need for a single merge, up to a combined 50MB — plenty for most everyday document merges.
Can I control the order the files are combined in?
Yes — files are merged in the order you upload them, so arrange your file selection accordingly before submitting.
