How do I merge multiple PDFs into one?

Upload your PDF files (drag and drop or click to select), arrange them in the desired order using up/down arrows, then click 'Merge PDFs'. Your combined file downloads automatically.

Can I merge more than 2 PDFs?

Yes! Merge unlimited PDF files. There's no limit on the number of PDFs you can combine into one document.

Can I change the order of PDFs before merging?

Yes! Use the up/down arrow buttons next to each PDF to reorder them. The order shown is exactly how they'll appear in the merged file.

What's the maximum file size?

There are no file size limits. Merge PDFs of any size since all processing happens locally in your browser.

Are my PDFs uploaded to a server?

No! All PDF merging happens 100% in your browser. Your files never leave your computer, ensuring complete privacy and security.

Can I merge password-protected PDFs?

Password-protected PDFs cannot be merged. Remove password protection first, then use this tool to merge them.
