Merge PDF Files Online — Free & Private

Pick two or more PDFs and PDFKitNow stitches them together, in the order you select them, into one file. The merge runs inside your browser, so your documents aren't uploaded anywhere.

How to merge pdf

  1. Click the file picker and select two or more PDF files (hold Ctrl/Cmd to multi-select).
  2. Files are combined in the order they appear in the list.
  3. Click "Merge & Download" — the combined PDF downloads immediately.

Frequently asked questions

Can I control the order the files are merged in?

Yes — files are merged in the order you selected them in the file picker. Re-select them in the order you want if you need to change it.

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

No fixed limit — we don't cap the number of files you can merge. Very large batches are ultimately limited by how much memory your device and browser can give the page, not by a rule on our side.

Can I merge PDFs without uploading them anywhere?

Yes. This tool does the merging with code running inside your browser tab, so the files you pick stay on your device — they aren't sent to a server for processing.

Do I need an account, and will the result have a watermark?

No account, no sign-up, and no watermark or branding is added to the merged PDF. What you download is just your documents joined together.

Will merging break bookmarks, links, or form fields?

Page content, text, and images carry over intact. Document-level extras such as bookmarks, internal links, and interactive form fields may not survive the merge, so check the output if your files rely on them.

Can I merge a password-protected PDF?

Not directly — remove the password first with the Unlock PDF tool (you'll need the current password), then merge the unlocked copy.
