About this converter
One attachment instead of nine
Applications, invoices, signed pages and scanned appendices arrive as separate files and almost always need to go out as one. Merging keeps the page order you set, so an application form followed by three certificates stays in that sequence.
What is preserved
Page sizes are kept per page, so an A4 document merged with a US Letter one keeps both shapes rather than scaling either. The tool copies page content, images and fonts. Document-level bookmarks, interactive forms and links are not guaranteed to survive; inspect the merged file before sharing it.
PDF to PDF: common questions
Can I change the order after adding files?
Yes. Every file appears as a row you can drag, and the list order is the order of the merged document. You can also remove a file without starting over.
Is there a limit on how many PDFs I can merge?
Up to 20 files per job, 100 MB each. For very large sets, merge in batches and then merge the results.
Do the original files change?
No. Merging writes a new PDF and leaves every source file exactly as it was.
What if one file is password protected?
A PDF that needs a password to open cannot be read at all, so the job stops and names the file. Save an unlocked copy from your PDF reader and merge that instead. A PDF that only restricts editing does open, because the merge happens on your own computer.
