Combine PDF files into one
A free PDF merger that joins several PDFs into a single document, in whatever order you choose. Unlimited, with nothing re-encoded, so the pages come out exactly as they went in.
or tap to browse — select several at once
Drag to reorder before merging. Nothing is re-encoded, so quality is untouched.
Nothing is re-encoded
Merging copies each page across exactly as it is. Text stays selectable, images keep their original resolution, and the result is visually identical to the documents that went in. Unlike compression, merging is completely lossless — there is no quality setting here because there is no quality decision to make.
Order matters more than people expect
Arrange your files before merging rather than after. Documents assembled for an application are usually expected in a stated order — cover letter, then CV, then certificates — and a merged PDF cannot be reordered by dragging afterwards without starting again. Worth checking the list twice before you press the button; it costs seconds, where redoing it costs the whole job.
Combining and then making it smaller
A merged PDF is the sum of its parts, so five 2 MB documents produce a 10 MB one. That is arithmetic rather than a fault, but it catches people out when the form they are filling in caps uploads at 5 MB. Merging and compressing are two separate steps, in that order: combine first so the compressor sees the whole document, then shrink the result. When your merged file appears, this tool offers to pass it straight to the PDF compressor without you downloading and re-uploading it.
What comes across, and what does not
Pages, text, images and page sizes all survive exactly. Internal links and bookmarks generally do not: a link that pointed to “page 3” of a document that is now pages 14 to 20 has nowhere sensible to go, so merged files usually lose their navigation. Fillable form fields are the other thing to check — if two documents use the same field names, merging them can produce a file where filling one box fills another. For a form someone else has to complete, send it separately rather than merged.
Frequently asked questions
How many PDFs can I combine at once?
There is no imposed limit, no account requirement and no daily cap. Very large batches of very large documents are the practical ceiling rather than a rule — if a merge of dozens of heavy files struggles, combine them in two passes and then merge the two results.
My merged PDF is too big to upload. How do I combine and compress?
Merge first, then compress the result — that order matters, because compressing each file separately and then merging leaves you with the sum of several already-degraded documents. When the merged file is ready you will be offered a link straight to the PDF compressor with it already loaded, so there is no downloading and re-uploading in between.
Will merging reduce the quality of my documents?
No. Pages are copied without being re-encoded, so the merged file is visually identical to the originals.
Can I combine a Word document with a PDF?
Not directly — everything must be a PDF first. Word, Google Docs and most other editors export to PDF, and those exports merge here normally. If you would rather not open the document at all, the document converter turns Word, Excel and PowerPoint files into PDFs that you can then merge.
Can I merge a password-protected PDF?
Not while it is locked. Open it with the password in any PDF reader, save an unprotected copy, and merge that. A tool that could bypass the protection would rather defeat the point of it.
