Combining several PDFs into one document is one of the most common file-management tasks, whether you're assembling a contract from separate exhibits, stitching together scanned pages, or building a single report out of chapters written by different people. Doing it by hand in a desktop PDF editor usually means opening a paid application just for a two-minute task.
pdfhubb's merge tool skips that step entirely. Upload as many PDFs as you need, drag them into the exact order you want, and download one combined file — no software to install, and no page limit imposed on top of your plan's file size limit.
Need to go the other way, or handle a related step first? Take a look at our Split PDF tool.

Privacy and Security
Files you upload to merge are processed in memory and in temporary storage only for as long as the job takes to complete. Once you download your result, the source files and the merged output are automatically deleted from our servers — we don't keep copies, and we don't read or analyze the content of your documents.
