How to use merge pdf
- Choose two to ten PDFs, each under 10 MB.
- Preview pages, set ranges such as 1-3,5, and reorder files by dragging or using Move up/Move down.
- Merge and download the resulting PDF. Processing is capped at 200 input pages.
A simple example
To keep the first two pages from one document and the last page from another, select 1-2 and the page number respectively.
What to keep in mind
Password-protected PDFs and signature fields are rejected. Internal page bookmarks are preserved when their destination pages are selected; external actions and unsupported destinations are not copied. Interactive forms and attachments are not preserved. PDF files can contain unsafe content; this is not a sanitizer.
Good questions. Clear answers.
Are PDFs uploaded?
No. A separate browser worker performs the merge and is terminated on cancellation or timeout.
Can I merge signed PDFs?
No. Signed PDFs and signature fields are rejected because a merge would change the signed document. Keep the originals.
