01 / How it works
How to merge PDF files
Choose your PDFs
Add two or more ordinary PDFs. Each file's page count appears after checking.
Set the order
Move files up or down. Pages within each file keep their original order.
Merge and download
Combine the files, then download the result. Your originals remain unchanged.
02 / FAQ
Before you start
Are my PDFs uploaded?
No. File contents are read and processed in this browser. No account or upload is required.
Will merging change page sizes?
Pages retain their original dimensions and rotation. Text is not converted into an image. Review the output if your files contain links or special PDF features.
Can I merge scanned PDFs?
Yes, ordinary scanned PDFs can be combined. This does not recognize text or make scans searchable.
Can I merge signed or fillable PDFs?
Interactive forms and signature fields are not supported. Editing a digitally signed file can invalidate its signature; use an unsigned, non-interactive copy.
