Stays in your browser — not uploaded to our servers.

2. Merge
Good to know
- Up to 20 PDFs per merge, 50 MB per file, 100 MB total. Limits are checked before files are read.
- Encrypted, XFA, empty or damaged PDFs are rejected with a clear message. Remove them before you can merge — you will not see technical error text.
- Pages are copied as-is (text and images stay). This tool does not compress PDFs. To split, use Split PDF files.
Questions
Are my files uploaded?
No. Reading and merging run in your browser. Files are not uploaded to our servers. The only network call is the optional feedback form.
Does the order matter?
Yes. Use Up / Down to set the order; the merged PDF follows the list from top to bottom.
What about password-protected PDFs?
They cannot be merged here. Remove the password elsewhere, then add the unlocked file.
Is it free?
Yes. Merging is free, with no sign-up, within the limits above.
Can I split or compress?
Split is available at /tools/split-pdf-files. Honest browser-only compression is still under review.
