Frequently Asked Questions
How many PDFs can I merge at once?
You can merge between 2 and 20 PDF files in a single run. Select them all together in the file picker and they are joined in the order shown.
Is merging PDFs free?
Yes, merging is completely free here and needs no account. Files are uploaded to the server, joined, and a download button for merged.pdf appears.
Will the page order stay correct?
Yes. Pages appear in the same order as the files you selected, with each document's own pages kept intact from first to last.
What if one file is not a PDF?
The tool checks every file before uploading. If a file is not a PDF, you get a clear error naming that file so you can replace it.
