About this tool
Can I put the second document first?
Yes. Move the selected files into the required order before merging. Pages within each input retain their order. Open the combined result and check where one document ends and the next begins.
Will merging scan my documents into pictures?
No. PDF pages are copied rather than photographed. This does not guarantee preservation of document-level bookmarks, forms or signatures.
What should I inspect before sharing the merge pdf output?
Unlock password-protected PDFs with their existing password, then return here. Interactive forms, bookmarks, and signatures may not carry over. Download the output and open it in the receiving application. A browser download request does not confirm that saving finished.
