How Merge PDF works

  1. 1.Add two or more PDFs (up to 20).
  2. 2.Drag files to reorder, or use Sort A–Z / by date. Rotate a file if its pages need turning.
  3. 3.Pick Simple merge or With divider pages.
  4. 4.Press Process and download the combined PDF.

Privacy

This tool runs entirely in your browser. Your files are never uploaded to a server, never stored by PDFZova, and never shared with anyone. Closing the tab discards them. The only exception is if a future tool is explicitly labelled as server-processed — this tool is not one of those.

Frequently asked questions

Are bookmarks kept?

No. Browser merging keeps every page but cannot carry bookmarks (outlines) across documents. The merged file opens at page 1 like any normal PDF.

Does merging change my files?

No — your originals are untouched. Only the new merged file is created, on your device.

Can I merge files with different page sizes?

Yes. Each page keeps its original size in the merged file — pages are not resized to match each other.

Can I merge a password-protected PDF?

Not directly. Unlock it first with the Unlock PDF tool, then merge the unlocked copy.

Can I merge scanned PDFs?

Yes, as pages. Scanned pages stay images in the merged file — merging does not add selectable text to them.

About Merge PDF

Combining PDFs should not mean uploading private documents to a server. Merge PDF joins two or more PDFs into a single document, in the order you choose, entirely in your browser. Add the files, reorder them with the arrow buttons, and download one finished PDF.

Output
A single PDF (.pdf) with all pages in your chosen order
File limit

When to merge PDFs

Merging fits documents that belong together: report chapters assembled into one report, an application form with its supporting documents, or scanned sections that need to be in order. The finished file follows the file order you set — drag files into place, or sort them — and each file's pages keep their original order and size.

Simple merge or With divider pages?

Simple merge joins your files back to back into one document. With divider pages inserts a blank page between each file, which is handy for separating chapters or sections so a reader can see where one document ends and the next begins. Pick the divider option when the result will be read or printed as a whole; pick Simple when the files are really one continuous document.

When merging will not help

Merging keeps every page, but it cannot carry bookmarks (outlines) across documents, so the merged file opens at page 1 like any normal PDF. Pages are copied, not re-rendered, which also means scanned pages stay images — merging does not add selectable text to them. And a password-protected file cannot be merged until it has been unlocked first.
