What this tool does
For standard PDFs that the browser library can read, the tool preserves page order, copies pages into a new PDF, and exports a merged document in the selected order.
Use this page when you need to combine several PDFs into one document and prefer not to upload private documents to a server-based merger.
Best uses
Useful for
Combining forms, receipts, invoices, statements, or supporting documents into one packet.
Useful for
Ordering several PDFs before submitting them through a portal.
Useful for
Creating a single local output from files stored on your device.
Useful for
Avoiding cloud upload for everyday PDF combining tasks.
How to use
- Add two or more PDF files.
- Move files into the order you want.
- Click Merge PDF.
- Download the combined PDF and open it to verify page order.
Privacy and local processing
Local workflow
- Add the PDF files in the order you want them to appear.
- Use move up and move down controls if the order is wrong.
- Merge the files locally and download the new PDF.
- Open the merged copy and verify page count, order, rotation, and readability.
Before sharing the output
- Check that each document appears exactly once and in the right position.
- Verify forms, links, bookmarks, annotations, and signatures if the PDF is important.
- Be aware that encrypted or corrupted PDFs may fail to load.
- Keep originals until you confirm the merged output is correct.
Supported files and limitations
Supported: PDF files. Recommended max size: 200 MB or 500 pages total.
- Password-protected, corrupted, encrypted, XFA, or very large PDFs may fail or need a clear error message.
- This tool combines pages; it does not edit existing text inside PDFs.
- Digital signatures and special interactive behavior may not remain valid after modification.
Local PDF merge vs online PDF merge
Many online PDF mergers require uploading documents. A local browser merger keeps supported files inside the browser session and creates the output locally. This is safer for everyday privacy, but complex PDFs should still be checked carefully after export.
Common mistakes to avoid
- Do not use merging as redaction or privacy cleaning.
- Do not merge confidential documents on a shared or untrusted device.
- Do not assume all interactive PDF features survive every client-side workflow.
- Do not send the result until you review the full document.
FAQ
Can I reorder PDFs before merging?
Yes. Use the up and down controls in the selected file list.
Are my PDFs uploaded?
No. The browser-only version reads and merges files locally.
Can I merge scanned PDFs?
Yes, if they are valid PDFs. Scanned pages are just pages inside the document.
Why did my PDF fail?
The most common reasons are encryption, corruption, very large file size, or unsupported PDF features.
Can I merge images into a PDF?
That should be handled by a future Images to PDF tool, not this launch tool.
