How ToolsHub Merges PDFs Locally

ToolsHub uses the open-source PDF-Lib engine running directly in your browser. Each PDF document's object tree and cross-reference catalog are loaded into local memory. The page dictionaries, font streams, and content streams are copied into a newly generated PDF catalog without transmitting any bytes to an external server.

How to use PDF Merge

Select the PDFs you want to combine, arrange their order and merge them. Open the downloaded document to check page order.

What to check before using the result

Encrypted or unsupported PDFs may fail. Keep original documents and check signatures and interactive forms after processing.

Example: Combining a cover page and report

Select the cover PDF and report PDF, arrange the cover first, and merge. Open the downloaded file to confirm page order and orientation. Protected files or interactive features may require a dedicated PDF application.

Free to use; no account required. For browser requirements and processing limits, read the ToolsHub FAQ. See how local processing works in our privacy policy.
