Frequently Asked Questions

How many PDFs can I merge at once?

You can merge as many PDFs as you need in a single operation. Simply upload all your files and they will all be combined in the order they appear in the list.

Can I reorder pages before merging?

The PDFs are merged in the order you add them. To control the final order, add your PDFs in the sequence you want them to appear.

Will merging PDFs affect the quality?

No. PDF merging is a structural operation — the tool copies pages from each source PDF into a new combined PDF without re-rendering anything. All fonts, images, and formatting are preserved exactly.

Can I merge password-protected PDFs?

Password-protected PDFs cannot be merged by this tool. Remove password protection from each PDF first before merging here.

How do I merge PDFs on mobile without an app?

Open this page on your mobile browser, tap the upload area to select PDFs from your Files app, add all files, then tap Merge & Download. No app installation required.
