About the PDF Merge Tool

An online tool to combine multiple PDF files into a single PDF in any order you like - perfect for invoices, contracts, scanned documents, and reports. You can also specify a page range for each file to extract and merge only the pages you need. The biggest advantage is that your files are never sent to a server. Popular online PDF services (such as Smallpdf or iLovePDF) require you to upload your files and often limit free usage. This tool runs entirely in your browser, so you can merge even confidential documents safely, with unlimited use, no sign-up, and no watermark.

To split or extract pages from a single PDF instead, use the PDF Split tool; to reorder or delete pages, try the PDF Organize tool; and to build a PDF from images, see the Image to PDF tool. Learn more about how browser-based tools keep your data private in our guide to browser-based PDF tool security.

FAQ

Are my PDFs uploaded to a server?
No. All processing happens locally in your browser. Your PDF files are never sent to or stored on any server, so even confidential documents are safe.
Is there a limit on the number or size of files?
There is no limit on the number of files. Since nothing is uploaded there is no server-side size limit either, though very large or numerous files may take longer to process depending on your device memory.
Does the merged PDF have a watermark?
No. The output PDF contains no watermark or ads. Your original content is merged as-is.
Can I merge password-protected PDFs?
Encrypted (password-protected) PDFs may not be merged. Please remove the password before adding such files.
Can I change the merge order?
Yes. Drag items in the list or use the ▲▼ buttons on each item. Files are merged from the top of the list downward.
Can I merge only specific pages from each file?
Yes. Enter a page range such as "1-3,5" in each file's page-range field to extract and merge only those pages. Leave it blank to include all pages. If you only need to extract or split a single PDF, try the PDF Split or PDF Organize tools.
Can I see the total page count and file size before merging?
Yes. When you add files, an estimated total page count and total size appear at the top of the list. If you set a page range, the totals update automatically based on the pages you selected, so you can check the result before merging.
