Direct answer
To merge PDFs without uploading them, open the browser-local PDF merger, select at least two files, arrange their order, merge them and review the downloaded copy. The files stay on your device during processing.
Steps
- Open the PDF merger.
- Select at least two PDFs. The tool accepts up to 50 files with a combined size of 50 MiB.
- Arrange the files in the order the final document should use.
- Choose Merge PDFs, download the result and check the page order.
What merging changes
The merger copies the pages into a new PDF. It does not edit the words on those pages. Keep the original files until you have checked the combined document.
Check before sending
Merging can invalidate digital signatures and may not preserve interactive form fields, bookmarks or metadata. Open the output in a PDF viewer and check the first, middle and last pages.
When a file will not merge
Encrypted, damaged or unsupported PDFs may fail. Confirm that each file opens normally and try an unencrypted copy only when you are authorised to process it.
Questions
Do I need an account to merge PDFs?
No. The browser-local merger works without an account or email address.
Can I merge PDFs in a different order?
Yes. Arrange the selected files before choosing Merge PDFs.
