FAQs about Merge PDF
Are my PDF files uploaded anywhere?
No. Merging happens entirely inside your browser using your own device, so your documents never leave your computer or get sent to any server.
How many PDFs can I merge at once?
You can add as many as you like and combine them into a single file. The only real limit is your device memory, since all of the work is done locally.
Can I choose the order of the files?
Yes. After adding your files, use the up and down arrows next to each one to arrange them. The final PDF follows the order shown in the list.
Will merging reduce the quality of my PDFs?
No. Pages are copied exactly as they are, so text stays sharp and images keep their resolution. Merging joins the documents without re-compressing them.
Is this really free?
Yes, completely free with no sign-up, no watermark, and no file-size paywall. Everything powerful, nothing paid.
