How to merge PDF files

Sometimes you need several PDFs to travel as one: exhibits in a single court bundle, a contract with its annexes, or a set of scans you want to send together. QuietPDFcan combine them into one file without uploading anything. Here’s how it works.

How do I merge PDFs?

Open the merge PDF tool, drop in two or more PDFs, arrange them, and click Merge. Then download the combined file. It all happens in your browser tab; nothing is uploaded.

Can I choose the order?

Yes. After you add your files, reorder them with the up and down arrows (or remove one you didn’t mean to add). The pages are combined from top to bottom, exactly as listed, so the order you see is the order you get.

Why does it run in my browser?

Most “combine PDF” services upload your documents to a server to stitch them together. For anything sensitive (signed agreements, IDs, statements), that hands copies to a third party. QuietPDF reads and merges the files locally, so the combined PDF is built on your own machine and nothing ever leaves your device.

Is it safe for confidential documents?

That’s exactly the case local merging is built for. A merge often combines your mostsensitive material into one file, so uploading the set multiplies the exposure. In the Philippines, the Data Privacy Act (RA 10173) treats an online tool that receives your files as a processor, and a lawyer’s confidentiality duties point the same way. When nothing is uploaded, there’s no third-party copy to leak or account for. The blog post on merging confidential PDFs and the Data Privacy Act goes through this in detail.

A quick workflow for a clean bundle

For anything more than two files, a little prep helps. Rename the documents with a number prefix (01-, 02-, 03-) so they sort in the right order before you even add them, drop the whole set in at once, nudge anything out of place with the up and down arrows, then merge. Open the result and skim it once to confirm the order is right and no page is missing.

Does merging make the file bigger?

A merged PDF is roughly the sum of its parts, because nothing is re-compressed — every page keeps its original quality. If the combined file is larger than you’d like (a stack of scans, for instance), run it through the compressor afterward to bring the size down before you send it.
