How to merge PDF files online for free
This free online PDF merger combines 2 to 20 PDF documents into one file. The total upload can be up to 64 MB. To merge your files:
- Add your PDF files. Select several documents at once or add them one at a time;
- Arrange the file order. Use Up and Down to move a file, and remove anything you do not need;
- Click Merge PDF. When the merge is complete, download the combined document.
Combine PDF files in the right order
Files are combined from top to bottom. All pages from the first PDF come first, followed by every page from the second PDF, and so on. The list is not sorted by name or date, so set the order before merging.
Up and Down move whole PDF files. They do not rearrange individual pages inside a file.
Merge PDFs without losing quality
Existing PDF pages are copied into the new document without being turned into images or compressed again. Searchable text stays searchable and selectable, while images, fonts and page formatting are preserved.
Each page also keeps its original size and orientation. A4 and letter pages, portrait scans, landscape spreadsheets and presentation slides can all appear in the same merged PDF.
Contracts, bank statements, tax documents and scans
A single PDF is useful when a portal accepts one upload or related documents need to stay together. Combine a contract with its annexes, monthly bank statements and payslips for an application, tax forms with receipts, or separate scans from the same document.
Merge PDFs on Windows, Mac, iPhone and Android
The PDF merger works in a browser on Windows, macOS, Linux, iPhone and Android. No desktop software, mobile app or browser extension is required. On a phone, select PDFs from your device and download the merged file through the browser.
How do I merge multiple PDF files into one?
Add 2 to 20 PDF files, arrange them with the Up and Down buttons, then click Merge PDF. Download the combined document when processing is complete.
Can I merge PDF files online for free?
Yes. The PDF merger is free to use, with no account or software installation required. It does not add a watermark to the finished document.
What order will the merged PDF files follow?
Files are combined from top to bottom. All pages from the first PDF come first, followed by the second PDF and the remaining files in order.
Can I rearrange individual PDF pages before merging?
No. This tool can change the order of whole PDF files only. It does not rearrange or delete individual pages inside them.
Does merging PDF files reduce their quality?
No. Pages are not converted into images or compressed again. Searchable text, images, fonts and page formatting are preserved in the merged PDF.
How many PDF files can I merge at once?
You can merge 2 to 20 PDF files with a combined upload size of up to 64 MB. The size limit applies to the entire upload, not to each file separately.
Can I combine pages with different sizes and orientations?
Yes. A4 and letter pages, portrait scans and landscape slides can be combined in one PDF. Every page keeps its original dimensions and orientation.
Can I merge password-protected PDF files?
No. Remove the password in an application that can open the document, then upload the unlocked PDF again.
Will a digital signature remain valid after merging PDFs?
No. Merging creates a new file, which invalidates signatures on the source documents. If the final PDF needs a signature, sign it after the files have been merged.
Can I merge PDF with JPG, PNG or Word files?
No, this page accepts PDF files only. Convert the image or Word document to PDF first, then add it to the other files.
Can I merge PDF files on a phone?
