FAQ about Batch PDF Merger Online

How many PDFs can I merge at once for free?

PDNob's free online pdf batch merger accepts up to 10 PDFs in a single session, with each file capped at 15MB. That covers the bulk of contracts, decks, and scanned packets. Paid PDNob online raises both the file count and the per-file cap; the desktop app removes the upload limit entirely for very large batches.

Is batch pdf merger safe for sensitive documents?

Yes, when the tool meets a clear security bar. PDNob encrypts every upload, merge, and download with 256-bit SSL, auto-deletes source files shortly after processing, and follows GDPR-aligned practices. The answer to "is it safe to batch merge online" with PDNob is yes — the same pipeline protects single merges and 10-file batches equally.

Can I reorder files before batch merging?

Yes. After upload, the merge canvas shows every file as a card you can drag up or down the list. The final merged PDF follows the order you set, so chapters, exhibits, and schedules always land where you expect. You can also rename files inline to keep the merged document organized.

Will merging change my original PDFs?

No. PDNob's pdf batch merger only reads your files and writes a new combined PDF — the originals stay exactly as you uploaded them. Fonts, form fields, and annotations inside each page are preserved, so batch merge pdf files free without worrying about hidden reformatting.

Can I batch merge password-protected PDFs?

Open or owner-protected PDFs can be combined with the right password — the merger will prompt you once per file, then merge everything into one output. Files with only viewer restrictions (no password required to open) merge without prompts on the free online plan.

Do I need to install anything to batch merge PDFs?

No installation is required on the free online plan — open PDNob in Chrome, Firefox, Edge, or Safari and start merging. For heavy daily batches, the PDNob desktop app installs once and removes the upload cap, so you can batch merge pdf files online or offline with the same workflow.
