Questions about merging PDFs

How do I merge multiple PDFs into one?

Choose at least two PDFs, arrange the files from top to bottom, select Combine PDFs, then check and save the generated PDF.

Can I change the PDF order?

Yes. Use Move up and Move down before combining. This version moves whole files and keeps the pages inside each file in their original order.

Are my PDFs uploaded?

No. Document contents and filenames are processed in your browser and are not uploaded to Partners in Combine. The hosting provider still receives ordinary website request data when it delivers the page.

Can I combine scanned PDFs?

Yes, ordinary image-only scanned PDFs are supported. This tool combines existing PDFs; it does not scan paper, run OCR or turn photos into PDFs.

Can I merge PDFs on a phone?

The web tool is designed for phone and desktop browsers. Save PDF remains available as a fallback. File sharing appears only when the current device and browser say it is supported.

Which PDFs are not supported?

Password-protected PDFs and PDFs containing forms, signatures, annotations, links, bookmarks, embedded attachments or accessibility tags are rejected. See Help for the full current boundary.
