MERGE ORDER

Merge order

The list order becomes the page order of the merged document.

Move a file with the arrow buttons in the list; pages inside each file always keep their own order.

HOW IT WORKS

How does it work?

Four stops on the same rail; nothing else to learn.

  1. Drop

    Select two or more PDFs or drag and drop them onto the window; no file may exceed 100 MB.

  2. Order

    Set the order with the arrow buttons in the file list: the first file in the list becomes the first pages of the merged document.

  3. Run

    Press Run; pages are copied into a single document without being redrawn or recompressed.

  4. Download

    Download the merged PDF; it is named after the first file in your list.

FAQ

Frequently asked questions

Short answers on order, quality and limits.

Is merging PDF files free?

Yes — the tool is free and works without an account. Upload your PDFs, set the order and download the merged document.

Does merging reduce quality?

No. Nothing is redrawn or recompressed: every page moves into the combined document exactly as it was, so text stays sharp and images keep their original quality.

How is the page order decided?

The list order is the page order: the first file's pages come first, then the next file's. Use the arrow buttons on the file list to reorder before running; pages inside each file keep their own order.

What happens with a password-protected PDF?

Encrypted or damaged files cannot be read, and the tool tells you which file caused the problem. Save an unlocked copy of that file and run the merge again.

How many files can I merge at once?

A single run takes up to 20 files and 1,000 pages in total, with a per-file limit of 100 MB. For bigger jobs, merge in groups and then merge the results.

Do my original files change?

No. Merging works on the temporary copies you upload; the files on your device stay untouched. What you download is a new document.

Do links and bookmarks carry over to the merged PDF?

Page content is copied exactly as it looks, but interactive extras such as clickable links, bookmarks and form fields are not carried into the merged file.

OVERVIEW

When do you need to merge PDF files?

Three everyday cases and what the output looks like.

A job application that asks for a single PDF, a month of invoices that should reach the accountant as one file, chapters scanned one by one: separate PDFs often need to become a single document. PdfMerge combines two or more PDF files into one — you decide the order, the tool does the rest.

Merging is lossless: pages are never redrawn or recompressed; every page moves into the combined document untouched, so text stays selectable and pictures keep their original sharpness. The result downloads as a single PDF that takes its name from the first file in your list.

The list order is the page order: the first file's pages come first, then the next file's, and so on. Before running, you can reorder the files with the arrow buttons. A single run takes up to 20 files and 1,000 pages in total; the size limit is 100 MB per file.

Reports and annexes

Bundle a report, its annexes and the signed cover page into one PDF before you send it; the recipient opens a single document in exactly the order you chose.

Monthly accounting bundles

Merge the month's invoices and receipts into one document before sending them on; one tidy file instead of a dozen separate attachments.

Scans and lecture notes

Put separately scanned chapters or note batches back together as one document that reads from start to finish.
