Merge PDF
Combine several PDFs into one file, in exactly the order you want.
This tool merges your PDF files directly in your browser: unlike most online services, your documents are never uploaded to a server — ideal for contracts, invoices or confidential files. Add as many files as you need, reorder them with one click, and download a single PDF in seconds. Free, no sign-up, no watermark, no file limit.
How does it work?
- Drop your PDF files in the area above (or click to browse).
- Reorder them with the ↑ and ↓ arrows; remove any added by mistake.
- Click “Merge”: the merged.pdf file downloads immediately.
Frequently asked questions
Are my files uploaded to a server?
No. The merge is performed by your browser, on your device. Not a single byte of your documents goes through our servers — you can even disconnect from the internet once the page has loaded.
Is there a size or file count limit?
No imposed limit. The only constraint is your device's memory: merging dozens of PDFs with hundreds of pages works fine on any recent computer.
Is the page order preserved?
Yes. Documents are assembled in list order, and every page of every document is kept as-is, without recompression or quality loss.
Can I merge password-protected PDFs?
PDFs that require a password to open must be unlocked first. PDFs with simple restrictions (printing, copying) are accepted.
