Introduction
Merge PDF combines multiple PDF files into one document in your browser. Files never leave your device — everything runs locally with no upload to a server.
Step-by-step
- Select two or more PDF files (or drag them into the drop zone).
- Reorder files if needed — the list order becomes the page order.
- Click Merge PDFs.
- Download the combined PDF when processing finishes.
Worked example
Select cover.pdf, then body.pdf, then appendix.pdf. After merge, the download contains pages from cover, body, and appendix in that order.
Use cases
- Combine scanned pages or chapters into a single PDF
- Join invoices, contracts, or reports before sharing
- Assemble a packet from several exports without desktop software
Frequently asked questions
Are my files uploaded anywhere?
No. Merging happens entirely in your browser. Bestrao does not receive or store your PDFs.
Can I merge password-protected PDFs?
Encrypted or restricted PDFs often cannot be merged. Unlock them first, then try again.
Is there a file size limit?
Limits depend on your device memory. Very large PDFs may be slow or fail in the browser — try fewer or smaller files.
