Công cụ gộp PDF

How to use it

1. 1

   Drop at least two PDFs

   The drop zone accepts PDF files and you can add more in a second drop. Non-PDF files are rejected.

2. 2

   Put the list in reading order

   Use the up and down controls on each row. The top file becomes the start of the merged document.

3. 3

   Remove anything that should not be included

   The remove control drops a file from the list only. It does not delete the original from your computer.

4. 4

   Merge and download

   Click the merge button. You need at least two PDFs. The browser builds one file and downloads it.

Good uses

• Joining a signed page with the rest of an agreement.
• Combining several scanned chapters into one document.
• Building a single attachment from a proposal, an appendix, and a price sheet.
• Putting exported slides and a notes PDF into one handout.

Tips

• Name files so the list is obvious, then still check the order before you merge. File name order and visual order are not the same thing.
• If you only need pages 2–4 of one file, split that range out first, then merge the extract with the other documents.
• Very large image-heavy PDFs use memory in the tab. Close other heavy tabs if a big merge feels slow.
• Open the download and flip through the first and last pages. A reversed row is easier to catch before you send the file.

Limits to know

• At least two PDFs are required. A single file has nothing to merge with.
• Password-protected PDFs that the browser cannot open will fail. Unlock them in a tool that knows the password first.
• This does not edit text, compress images inside the PDF, or add page numbers.
