How to merge PDF files for free — no software needed
Merging multiple PDF files is one of the most common tasks when working with digital documents: reports, contracts, invoices, presentations. It is simpler than you might think, and you do not need to install any software.
When do you need to merge PDFs?
Here are some typical situations:
- You scanned a multi-page document as separate files and want a single PDF
- You need to attach several documents to an email as one file
- You are assembling a report from sections created by different colleagues
- You want to archive monthly invoices into a single annual document
How our tool works
Our merge PDF tool runs entirely in your browser: your files are never uploaded to a server. This means your documents stay private and secure.
Step 1 — Add your files
Drag your PDFs into the upload area or click to select them from your folder. You can add up to 20 files at once.
Step 2 — Set the order
The order in which the files appear in the list is the order of pages in the final document. Drag files to rearrange them.
Step 3 — Merge and download
Click Merge PDF and within seconds the combined file is ready to download.
Merging vs. inserting pages
"Merging" means taking two or more complete files and placing them one after the other. If instead you want to insert specific pages from one PDF into another, you should first split the PDF to extract the pages you need, then merge the pieces in the desired order.
File size limits
The tool runs entirely in the browser and handles files up to 150 MB per operation. For larger files it is advisable to compress them first with our PDF compressor.
Conclusion
Merging PDFs does not require expensive software or cloud service accounts. With a few clicks you can combine all your documents while keeping the original quality and keeping your data private.
