Frequently asked questions

How do I merge PDF files?

Drop your PDFs into QuietPDF below, arrange them in the order you want, and click Merge. The combined PDF is built right in your browser and downloads instantly, with no uploads and no signup.

Does merging upload my PDFs to a server?

No. QuietPDF combines your PDFs entirely in your browser using WebAssembly-free JavaScript. The files never leave your device, so even confidential documents stay private.

Can I choose the order the PDFs are combined in?

Yes. After you add your files, reorder them with the up/down arrows. They're merged from top to bottom, exactly as listed.

Is there a limit to how many PDFs I can merge?

There's no fixed limit. Because everything runs locally, the only real constraint is your device's memory, and a handful of typical documents merges in seconds.

Is it free?

Yes. QuietPDF is completely free, with no signup and no watermarks on the merged file.

What to know before you merge

Merging is straightforward, but a few details are worth knowing so the combined file comes out exactly the way you expect.

Your originals stay untouched

Merging reads copies of your files and writes a brand-new combined PDF — the original documents on your device are never changed. Nothing is re-compressed along the way either, so every page keeps the exact quality it had. If the combined file ends up larger than you’d like, you can shrink it afterward with the compressor.

Getting the order right

Pages are combined top to bottom in the order you arrange them, so set the order before you click Merge. A tip for large bundles: rename your files with a number prefix (01-, 02-, 03-) before adding them, so they line up correctly from the start and you only need small nudges with the up and down arrows.

What carries over — and what to check

All the page content — text, images, and vector graphics — comes across intact. Interactive extras such as form fields, bookmarks, or digital signatures can behave differently once documents are combined, so if a file has fillable fields you depend on, check them in the merged result. Password-protected files need to be unlocked before they can be merged.

When people reach for a merge

Combining exhibits into a single court bundle, attaching annexes to a contract, stapling a set of scanned receipts into one expense file, or assembling an application packet. Any time several documents need to travel as one, merging keeps them together and in the right order.
