PDF TOOL
Merge PDF
Combine multiple PDF files into one PDF locally in your browser.
ON-DEVICESelected input is processed in this browser.

The selected input stays under your control
On-device processing means the input is handled by browser APIs on the device running this page. Closing or refreshing the page normally clears the active in-memory working session.
Read the Privacy Policy →Prepare PDFs before combining them
Arrange the selected documents in the exact reading order before creating the merged file. The operation copies pages into a new PDF; it does not edit the text or guarantee that existing forms, signatures, or advanced document features remain interactive.
Open the downloaded PDF and check page order, orientation, links, forms, and signatures before sharing it.
What merging changes and preserves
Merging creates one document from the selected PDFs in their displayed order. It combines pages; it is not a PDF editor or document repair service.
Check the merged PDF
Open the downloaded result and review the first page, last page, page order, orientation, links, forms, and signatures. Complex interactive features can behave differently after pages are copied into a new document.
Choose a safe working order
Rename source files or arrange them before merging when sequence matters. Keep the originals until the final document has been reviewed and accepted by its recipient.
Questions about this tool
Can I merge password-protected PDFs?
A protected PDF may require its password or may block page copying. Remove protection only when you are authorized to do so.
Does merging compress the PDFs?
No. The tool combines pages and does not promise file-size reduction. Images and embedded assets normally remain part of the resulting PDF.
Combine PDF files in a controlled reading order
Build one PDF from selected documents and verify complex features afterward.
How to use it
- Choose two or more PDF files.
- Arrange them in the required order.
- Merge, download and inspect the completed document.
Supported input
- Standard PDF documents
- Multiple unencrypted or accessible PDF files
Worked example
Combine a cover sheet, twelve-page report and appendix into one client-ready PDF in that sequence.
Limitations
- Interactive forms and signatures may not remain valid.
- Merging does not compress page content.
Troubleshooting
- Remove or unlock protection only when authorized.
- Reorder source files before retrying if pages appear in the wrong sequence.
Tool-specific questions
Are bookmarks preserved?
Complex document navigation may not be retained; verify the result.
Can I merge scanned PDFs?
Yes, if each scan is a valid readable PDF.
Before you process
Can I use this merge pdf online without uploading my input?
Yes. This tool is labelled On-device, so the selected input is processed in your browser and is not sent to a ForgeMyFile processing API.
What happens if the browser cannot process it?
The tool shows a readable error and stops. It does not silently fall back to a cloud upload.
Why can performance differ between devices?
The browser is doing the work locally, so speed and practical file size depend on available memory, CPU and browser capabilities.
