How to merge PDF files online
- Choose two or more PDF files, or drag them into the drop zone. Add more files whenever you need.
- Drag the file rows into reading order. On a phone or keyboard, use the up and down buttons instead.
- Select “Merge PDFs”, then download the combined file. Your originals stay unchanged.
Bring a week of lecture slides, reading extracts, and practice questions together in a single document. The merger adds every page from each source PDF, following the order shown in the file list. Check that list before exporting: moving a file moves all of its pages together. If you only need a few pages from a source, use Split PDF first and merge the extracted file.
The browser reads your files and creates a new PDF locally. There is no upload queue, sign-in step, or daily tool quota. Keep the selected files under 150 MB in total, and use smaller batches on a phone with limited memory. Password-protected documents need an unlocked copy before they can be combined.
Ordinary page content, images, and existing page rotation are copied into the result. Document-level features such as bookmarks, interactive forms, attachments, or digital signatures may not carry over reliably. Review the downloaded PDF before sharing it, especially if the sources include forms. For studying, keep a copy of the finished document ready to use with the flashcard generator on the home page.
A few useful answers
Are my PDF files uploaded?
No. This merger reads and combines files in your browser. The selected file contents are not sent to a server.
Can I reorder the PDFs before merging?
Yes. Drag the file rows, or use the up and down arrow buttons. Every page in each file follows that file’s position.
Can I merge password-protected PDFs?
Save an unlocked copy in a PDF reader first. This tool does not remove passwords or bypass document protection.
Will bookmarks and digital signatures survive?
Page content is copied, but document-level bookmarks, forms, and signatures may not survive. Review the output before using it for official records.
