Merge PDF
Combine multiple PDF files into a single document without uploading anything.
Private: your files are processed in your browser and never uploaded.
Combine PDFs privately
This merge tool joins several PDF files into one document without sending anything to a server. Select the files in the order you want them, press Merge, and the combined PDF downloads straight from your browser. It is ideal for stitching together scanned pages, chapters, invoices, or signed contracts.
Because all processing is local, the tool works offline once the page has loaded and keeps confidential documents on your own device. That is the main difference from typical online merge sites, which upload your files to their servers first.
How it works
The tool reads each file, copies every page into a new document in list order, and saves the result. Standard page content is preserved exactly; complex form fields or annotations may not always carry across, so check the output if your PDFs contain interactive elements.
Frequently Asked Questions
Are my PDF files uploaded anywhere?
No. The merge happens entirely in your browser using a local library. Your files never leave your device and nothing is sent to a server.
In what order are the files combined?
Files are merged in the order they appear in the list, which is the order you selected them. Add them in the sequence you want the final document to follow.
Is there a file size or page limit?
There is no fixed limit, but very large files use your device memory since all processing is local. Extremely large merges may be slow on low-memory devices.
Does merging change the page content?
No. Pages are copied as-is into a new document, so text, images, and layout are preserved. Form fields and some interactive features may not carry over.
