Combine PDFs without uploading them
Merging happens in your browser with the open-source pdf-lib library, so bank statements, ID documents and contracts are never sent anywhere. Pages are copied without re-compression, keeping text, links and quality exactly as they were.
Need to remove or reorder pages after merging? Use Organize PDF. File too big to email? Compress it.
How to use the Merge PDF tool
- Choose or drop your PDF files.
- Drag them into order, or press Sort A–Z.
- Optionally name the output file.
- Press Merge PDF; the file downloads automatically.

Frequently asked questions
How do I merge PDF files for free?
Choose two or more PDFs, put them in the order you want (drag them or use the arrows), and press Merge PDF. The combined file downloads straight away.
Is there a limit on files or size?
No. There is no upload, so there are no server limits. Very large files (hundreds of MB) depend on your device memory.
Will my PDFs keep their quality, links and text?
Yes. Pages are copied as they are, so text stays selectable and quality does not change.
Can I merge password-protected PDFs?
PDFs that need a password to open must be unlocked first. PDFs with only editing restrictions can be merged.
Is it safe for confidential documents?
Yes. Files are merged by your browser and never leave your device.
