Merge PDF files into one document without uploading them. Add two or more PDFs and each one appears in a list with its page count and size. Drag the rows into the order you want, or use the arrow buttons, then press Merge PDFs to download one combined file called merged.pdf. The pages are copied as they are, keeping their size, orientation and content.
How to merge PDF files
- Drop the PDFs on the box or tap it to choose them. The list shows each file's pages and size.
- Put the files in order. The top file comes first in the merged PDF.
- To use only part of a file, type the pages in its Pages box. Leave it empty for every page.
- Check the total page count above the list, then press Merge PDFs. The button turns on once two PDFs are ready.
- The download starts by itself. If it doesn't, use the Download again link in the message.
The same steps pull pages out of a single PDF. Merge PDFs needs two files, so add the document twice, type 2 in the first Pages box and 4-6 in the second, and the result is a new PDF with just pages 2, 4, 5 and 6.
Choosing pages
1-3, 5takes pages 1, 2, 3 and 5. Semicolons work as separators too.4-takes page 4 to the end, and-2takes the first two pages.- Pages are added in the order you type them, so
3, 1-2puts page 3 first. - A page can be listed twice to include it twice.
A range that runs backwards, such as 5-2, or a page number past the end of the file is marked in red with the valid range, and Merge PDFs stays off until you fix it. To take pages from the middle of one document and put them between pages of another, add the same file twice with a different range each time.
Example
| File | Pages in file | Pages box | Pages used |
|---|---|---|---|
| contract.pdf | 10 | 1-3, 5 | 4 |
| annex.pdf | 6 | 4- | 3 |
| signature.pdf | 2 | (empty) | 2 |
The merged.pdf has 9 pages: contract pages 1, 2, 3 and 5, then annex pages 4 to 6, then both signature pages.
Combine PDF files privately
The files are combined in your browser with pdf-lib, an open-source PDF library, and are never uploaded. That makes the PDF merger safe for contracts, payslips and bank statements, and it works without waiting for an upload on a slow connection.
To combine a PDF with photos, such as a form and pictures of a receipt, first make a PDF from the photos with JPG to PDF, then merge the two here. Photo pages make big files. If the result is too large to email, shrink the photos before making that PDF with the Image Compressor, and see the guide on compressing images without losing quality.
What carries over
- Text, images, page sizes and page rotation come across unchanged, and text stays selectable and searchable.
- Page sizes can be mixed. An A4 contract and a US Letter annex keep their own sizes in the merged file, and a printer set to fit the page scales each one.
- Bookmarks from the original files are not kept, and links that jump to another page may stop working.
- Fillable form fields may show their contents but stop being editable.
Password-protected PDFs
A PDF with a password or copy restrictions can't be merged, and the list marks it as locked. If you are allowed to, open it in a PDF reader with the password and save or print it as a new PDF, then add that copy. A file that isn't really a PDF, or is damaged, is marked in the list too and left out of the merge.
To send the merged file to a phone next to you without a cable or upload, try Optical File Transfer, which moves small files through QR codes. More file tools are in Everyday Tools.
