PDF combine

Merge multiple PDFs into one well-ordered document. Pages stay in file order, and multi-page files are appended page after page automatically.

Drop PDFs here

Choose two or more PDFs. You can reorder them before merging so the final document flows exactly the way you want.

Accepted: application/pdf, .pdf · Multiple files supported

Document order

Add two or more PDFs to build your merged document. The final PDF will follow this list from top to bottom.

Default behavior is optimized for the common case: every readable PDF is appended in the current list order, and if a source file contains multiple pages, those pages are kept together in sequence in the final document.

Best default setup: keep files in the intended reading order, combine only readable non-password-protected PDFs, and use clear filenames when merging reports, scans, forms, chapters, or appendices.
About this conversion

What this tool does

This tool combines complete PDF files into one document. It preserves page order inside each source and follows the file order shown in the workspace, which makes it useful for reports, chapters, invoices, scans, and appendices.

Instructions

How to convert your file

  4. 4

    Combine the files, download the result, and review the first and last page of every joined section.

Settings

Choose the right export settings

File order
The first listed PDF contributes all of its pages before the second file begins.
Page order
Pages inside each source keep their existing sequence; this tool does not reorder individual pages.
Source quality
Merging does not improve scans, run OCR, reduce file size, or repair damaged pages.
Final review
The output page count should equal the sum of the readable inputs. Open the download and check the first and last page of every source boundary, plus orientation and file order, before distributing it.
Example workflow

Example: assembling a report and appendices

Place the cover and report first, followed by each appendix in its intended order. Check the page counts shown for every source, merge, then inspect the transition page between the report and each appendix.

Limitations

Before you download

  • The workspace reorders whole files, not individual pages within a file.
  • Encrypted, password-protected, damaged, or unreadable PDFs must be unlocked or repaired first.
  • Interactive forms, signatures, bookmarks, scripts, or advanced PDF features may not behave exactly as in the original files.
FAQ

Questions about PDF combine

How are pages arranged?

Files are processed from top to bottom, and every source contributes its pages in their existing order.

Can I merge password-protected PDFs?

No. Unlock files you are authorised to use before adding them.

Does merging compress the PDF?

No. The purpose is document assembly, not optimisation or image compression.
