Merge PDF files

What Merge PDF does

Merge PDF combines multiple PDF files into a single document. You choose the order; the tool copies pages into one output file you can download as merged.pdf.

How to merge PDF files

1. Select or drop the PDF files you want to combine.
2. Reorder the list so pages appear in the sequence you need.
3. Tap Merge PDFs — processing runs in your browser.
4. Download merged.pdf when the result is ready.

Local browser processing

File conversion runs in your browser with a client-side library. BizNavi Hub does not receive your PDF contents for this merge step. Leaving or refreshing the page clears in-memory files.

Supported files

Standard PDF files (.pdf). Password-protected or heavily restricted PDFs may not open. Scanned image-only PDFs can still be merged as pages.

Limits

To keep browsers stable we limit file count, total size, and total pages. If you hit a limit, reduce files or split large documents first.

Common use cases

• Combine scanned pages or contract sections into one PDF.
• Assemble reports from several exported PDFs before sharing.
• Join invoices or attachments into a single downloadable file.

Limitations

This tool does not unlock encrypted PDFs, edit text, OCR scans, or convert Word documents. Very large files may fail on low-memory devices.

FAQ

Is Merge PDF free?

Yes. Basic merging does not require an account or a rewarded ad.

Are my files uploaded?

No. For this tool, merge processing happens in your browser and PDFs are not uploaded to BizNavi Hub servers for conversion.

What order are pages merged in?

The order of the selected file list. Use the arrows to reorder before merging.

Why did merge fail?

Common causes are encryption, corruption, or exceeding size/page limits. Try a smaller set of files.

Can I merge on my phone?

Yes on modern mobile browsers, within the same limits. Very large PDFs may need a desktop device.
