When to use this tool
A PDF merger is useful for joining report sections, invoices, application documents or scanned batches into one file that is simpler to send and store.
What to know before you start
Files are joined as complete documents. This tool does not remove duplicate pages, edit page content or create bookmarks between source files.
Temporary, private processing
No account is needed. Files are processed on this server and are not sent to third-party document processors or cloud storage. Uploads receive randomized server names and are deleted after download or automatically within 15 minutes. Page previews, where offered, are rendered locally in your browser. Avoid online processing for documents whose handling rules prohibit it.
Merge PDF questions
How many PDFs can I combine?
You can merge 2 to 20 PDFs in one job, within the 25 MB total upload limit and 200 combined pages.
Does merging change page quality?
Pages are copied into the combined PDF rather than converted to images, so ordinary page content is not intentionally recompressed.
Can I merge password-protected PDFs?
No. Remove the password first so the server can safely read and combine each file.
