About Merge PDF
Copy pages from up to 20 local PDF files into one downloadable document with reorder and removal controls.
Merge PDF copies pages from several documents into one new file in the order you choose. The operation changes neither source file and runs entirely in browser memory.
How to use it
- Select two or more PDF files.
- Use the arrow controls to arrange the merge order.
- Merge and download the new PDF.
Common use cases
- Combine invoices or receipts into one submission.
- Join report chapters exported by separate applications.
- Assemble scanned pages into a single document before archiving.
Worked example
Combine a cover page, a 12-page report, and a two-page appendix into one 15-page PDF.
Limitations and responsible use
- Up to 20 input files and 500 combined pages are supported per operation.
- Document-level bookmarks, portfolios, scripts, signatures, and some interactive structures may not survive page copying.
- Encrypted or password-protected PDFs are not supported.
Frequently asked questions
Can I change the merge order?
Yes. Use the arrow controls beside each selected file before creating the result.
Are the original PDFs modified?
No. The browser creates a new merged download and leaves every source file untouched.
