Merge several PDFs into one document
Add the files, put them in the order you want and download the combined document. Nothing is re-encoded along the way.
Drop your PDF files here
or pick several files from your device
- Add two or more PDFs. You can drop them onto the page or add them in several goes.
- Set the order by dragging the rows, or with the ↑ and ↓ arrows, which also work well on a phone.
- Press Merge PDF and download the result.
Pages are copied, not re-converted
Each document's pages are copied as they are into the final file. Text stays selectable text and images are not compressed again, so the merged PDF is exactly as sharp as the originals.
If the combined file ends up heavier than you would like, run it through the compressor afterwards — that is the step that actually reduces size.
Worth knowing
Password-protected PDFs cannot be merged directly; the protection has to be removed first.
Bookmarks and internal links belonging to each source document may not survive the combination, because the page numbering they point to changes.
The practical ceiling is 30 files per operation, and the real limit is how much memory your device has.
Frequently asked questions
How many PDFs can I merge at once?
Up to 30 files per operation. The real limit is your device's memory.
Does merging lose quality?
No. Pages are copied without being re-compressed, so the result is identical in quality to the sources.
Can I change the order after adding the files?
Yes, by dragging each row or using the ↑ and ↓ arrows.
Are my files uploaded?
No. The merge happens in this browser tab and the files are never sent to a CLEKARA server.
