Frequently Asked Questions

Does this tool upload my PDFs?

No. Merging is done locally in your browser using PDF-lib. Your PDFs are not uploaded or stored on our servers.

Can I control the order of merged PDFs?

Yes. After adding files, you can use the list to adjust their order. The first file in the list becomes the first pages in the merged PDF.

Is there a limit on the number of PDFs?

There is no hard limit in the tool, but browser memory will limit very large numbers or very large PDFs. For typical workflows it should be fine.

Will bookmarks or form fields be preserved?

Basic page content is preserved. More advanced PDF features like complex bookmarks or forms may not be fully preserved depending on PDF-lib support.

Is the merge PDF tool free?

Yes. It is free to use in your browser with no signup.
