Or choose them from your computer. They're processed in your browser, never uploaded.
Guide
How to merge several PDFs into one
Drag in the files, order them with the arrows and click "Merge PDF". Pages are copied as they are, with no recompression, so they keep their quality, links and selectable text.
Why we do not upload your files
Most PDF merging sites upload your documents to their servers. Here the work is done by your own browser using the pdf-lib library, so contracts, payslips and invoices never leave your computer.
How it works
- Drop or choose the PDFs you want to merge.
- Reorder them with the arrows.
- Click "Merge" and download the final PDF.
Frequently asked questions
Is it safe to merge PDFs here?
Files are processed in your own browser and never sent to a server, so nobody else can see them.
Is there a file or size limit?
We don't set limits. The only limit is your device's memory; on a normal computer you can merge dozens of documents.
Is quality lost when merging?
No. Pages are copied as they are, with their text, images and links.
Can I merge password-protected PDFs?
Encrypted PDFs may not open. Remove the protection first with the program that created them.
Do you do this every day?
If you merge documents, prepare invoices or copy data between programs every day, that can be automated, and it's what we do.
