How to Use the Merge PDF Tool?

Merging PDFs is one of those tasks that sounds trivial until you actually need to do it: a signed contract here, a scanned ID there, a few pages of a bank statement, and suddenly you are emailing four separate attachments that the recipient has to open one by one. This tool stitches any number of PDF files into a single document, in the order you choose. Drop your files in, drag them into the right sequence, and download one combined PDF that reads exactly the way you want it to.

It is a good fit for assembling application packages, combining monthly invoices into one archive, attaching appendices to a report, or merging scanned pages that came out of the scanner in several batches. Because the pages are appended rather than re-rendered, text stays selectable and searchable, fonts are preserved, and the output looks identical to the originals.

The tool runs entirely in your browser using client-side PDF libraries, so your documents are never uploaded to a server. That matters when you are handling contracts, tax documents, medical records, or anything else you would rather not send to a stranger's cloud. Once the page has loaded, you can even disconnect from the network and keep working.

One thing to keep in mind: merging copies pages as they are, so it does not compress or optimize the result. If you combine ten image-heavy scans, the output will be roughly as large as the sum of its parts. If the combined file is too big to email, run it through the Compress PDF tool afterwards. There is no hard limit on file count, but very large collections are bounded by your browser's available memory.
