Merge PDF: how it works
Combine PDF files without uploading confidential documents to a server. Reorder files by drag and drop and create a single PDF locally.
FAQ
Are my PDFs uploaded?
No. The documents are processed in your browser.
What happens to PDF forms?
You can flatten form fields before merging. Visible values are preserved reliably but are no longer editable afterwards.
Can I change the order?
Yes. Drag the selected files into the desired order before merging.
Your PDFs stay on your device.
Many online PDF services upload documents to a server for processing. LocalPDF takes a different approach: the actual document processing happens in your browser. This is especially useful for invoices, contracts and other sensitive documents.
Note: JavaScript libraries used for PDF processing are loaded from external CDNs. Your IP address may therefore be transmitted to the CDN provider, but your PDF files themselves are not transmitted.
