Merge PDF

About Merge PDF

Combining PDFs is one of the most common document chores - appending a signed page to a contract, bundling scanned pages with a cover letter, or joining reports into one file. This tool merges two or more PDFs into a single document, and the file list is drag-sortable so the merged output comes out in exactly the order you want.

How Merge PDF works

1. Drop in two or more PDF files.
2. Drag the list rows to set the order - the top file's pages come first.
3. Click Merge PDF and download the combined document.

Features

• Drag-to-reorder file list before merging
• Merges any number of PDFs into one document
• Keeps each source file's pages intact and in order
• Useful after scanning: generate pages with the phone scanner, then merge with an existing PDF

Tips for best results

• Name your source files with a number prefix (01-cover.pdf, 02-body.pdf) so the right order is obvious before you drag.
• Unlock any password-protected file first with Unlock PDF - locked PDFs cannot be merged.
• If the merged file is too big for email, run it through Compress PDF straight after.

FAQ

Can I merge PDFs of different page sizes?

Yes - each page keeps its original size inside the merged file.

Is there a page or file limit?

The limit depends on your plan's file-size allowance rather than a fixed page count.

How do I remove a file I added by mistake?

Use the trash button on the file's row in the list before merging.
