Combine PDF files into one — free and private
Merging PDFs is one of the most common document tasks: joining a cover letter with a résumé, stitching scanned pages into a single file, or bundling invoices before you send them. Our free Merge PDF tool combines any number of PDF documents into one clean file, and lets you drag each one into the exact order you want before you download.
Unlike most online PDF mergers, PDFnaro never uploads your files. The entire merge runs locally inside your web browser using JavaScript, so your documents stay on your device from start to finish. That makes it safe for contracts, bank statements, medical records and anything else you would rather not send to a stranger’s server.
Why merge PDFs with PDFnaro
There is no sign-up, no email, no watermark and no daily limit — you can merge as many PDFs as your device’s memory allows. Because everything happens in the browser, it works the same on Windows, Mac, Linux, Android and iPhone, and even keeps working offline once the page has loaded.
After merging you can send the result straight into our Compress PDF tool to shrink it for email, or use Organize PDF to fine-tune the page order. Every tool on the site follows the same privacy-first, no-upload approach.
Frequently asked questions
Is there a limit on how many PDFs I can merge?+
No fixed limit — you can merge as many files as your device memory allows, since everything runs locally in your browser.
Are my files uploaded to a server?+
No. Merging happens entirely on your device. Your PDFs never leave your browser, so it is safe for confidential documents.
Can I change the order of the files?+
Yes. After adding your PDFs, drag each file up or down in the list to set the exact order before you merge.
Does merging reduce the quality of my PDFs?+
No. Merging copies the original pages as-is, so text stays sharp and images keep their original quality.
