About the Merge PDF tool
This tool combines several PDF files into a single document, keeping every page in the order you choose. It is one of the most common document tasks — assembling chapters into one report, joining scanned pages, or combining invoices, contracts, and statements into a single file to send or archive.
How the merge preserves quality
The pages from each source PDF are imported directly into the new document, so text stays selectable and searchable, vector graphics stay sharp at any zoom, and the file size stays reasonable. This is different from tools that flatten each page into an image, which bloat the file and destroy the ability to select text. Here, a merged contract is still a real, searchable contract.
Controlling the order
The order matters when you merge. Files combine from the top of the list downward, and every page within each file is kept in its original sequence. The reorder controls let you arrange the documents exactly as they should appear before you process, so a cover letter goes first, the report in the middle, and appendices at the end, for example.
When merging is the right tool
Merge when you have multiple finished PDFs that belong together as one. If instead you need to pull pages out of a single PDF, the Split PDF tool is what you want; to make a PDF smaller, use the Compress PDF tool; and to turn photos or scans into a PDF, use the Image to PDF tool. Merging does not re-compress or alter the pages — it assembles them as they are.
Limits and compatibility
You can merge up to twenty PDFs at once, each up to 50 MB. Standard PDFs merge cleanly; a file that is password-protected or encrypted must be unlocked first, since its pages cannot be read while protected. Very unusual or damaged PDFs occasionally use features that cannot be imported, in which case the tool reports the problem rather than producing a broken file.
Privacy
Your files are uploaded over a secure connection, merged on the server, and offered for download. Both the uploads and the merged result are automatically deleted within an hour, so nothing lingers on the server.
Frequently Asked Questions
Does merging reduce the quality of my PDFs?
No. Pages are imported as-is, so text stays selectable and graphics stay sharp. The merge does not re-compress or flatten anything.
In what order are the files combined?
Top to bottom as shown in the list, with each file’s pages kept in their original order. Use the up and down arrows to rearrange before processing.
How many PDFs can I merge at once?
Up to twenty files, each up to 50 MB.
Can I merge a password-protected PDF?
Not while it is protected. Remove the password first, then merge, because encrypted pages cannot be read.
Are my documents kept on the server?
No. Uploads and the merged file are automatically deleted within an hour of processing.
