Does Windows have a built-in way to merge PDFs?

No — reading yes, merging no. The browser route does it without installing anything.

Is this safe on a work computer?

Nothing installs and files are processed temporarily then auto-deleted — no general cloud storage.

How many files can I merge?

Multi-file bundles within fair daily limits — typical document sets merge easily.

Merge PDF on Windows

Windows ships no PDF merger at all — the void usually filled by an Acrobat subscription or freeware roulette. The browser route fills it cleanly: upload, order, merge, done. Free with fair daily limits.

The Windows PDF gap

Edge reads PDFs; nothing native joins them. Desktop merger downloads bring toolbars and nag screens along, and office machines often forbid installs anyway — the browser needs no permission slip.

The clean route

Any browser on Windows 10 or 11: upload the files, set the order explicitly, merge server-side, download the combined document. Locked-down work PCs included.
