Merge PDF

Combine multiple PDF files into a single document. Drag to reorder, choose page size, orientation, margins, and optionally insert blank pages between files.

Practical guide

A final packet often starts as a pile of separate PDFs: a cover page, signed forms, receipts, report sections, and scanned attachments. Merge them after putting pages in the right order, and rotate sideways pages before the combined file goes to a client or archive.

Where this fits

Assemble client or finance packets

Combine supporting documents into one file so the recipient does not have to open five attachments and guess the order.

Create classroom or workshop handouts

Merge slides, worksheets, and reference pages into one download. If a section changes later, split the PDF again and replace only that part.

Preview a document set before sharing

After the packet is merged, you can export pages as images for thumbnails, approval previews, or documentation screenshots.

How to use Merge PDF

  1. 1Upload the PDF filesAdd every document that belongs in the final packet.
  2. 2Reorder the documentsDrag files into the reading order the recipient should see.
  3. 3Check page sizing optionsUse page size, orientation, margins, or blank dividers only when the combined document needs a consistent production format.
  4. 4Export one PDFDownload the merged file and open it once to confirm the page order before sending.

Practical notes

Name files before uploading

Prefixes like 01-cover, 02-contract, and 03-receipts make ordering easier when a packet has many documents.

Document packet workflow

Clean the source files before merging when possible; it is faster than fixing a long combined PDF afterward.

  1. 1

    Rotate PDF

    Fix scans that are sideways or upside down.

  2. 2

    Merge documents

  3. 3

    Split PDF

    Extract one section if the packet needs revision.

Questions worth checking

Does merging PDFs change the page content?

The goal is to assemble pages into one file. Layout options such as margins, orientation, or inserted blanks can change the final page presentation, so review the export before sharing.

What should I do with duplicate or unwanted pages?

Remove them before export if the merge interface shows them, or split the finished PDF afterward and keep only the needed ranges.

Why is page order the main thing to check?

A merged PDF is usually read straight through. One misplaced attachment can make a packet confusing even when every individual file is correct.
