Free forever · No watermark · Your files never leave your device

Combining PDF files should not require an account, a subscription, or sending your documents to a stranger’s server. ThePDFBuddy’s free merge tool joins multiple PDFs into one document right inside your browser, so what happens on your device stays on your device.

People merge PDFs every day: job applications that need a cover letter, résumé, and certificates in one file; expense reports with a stack of receipts; contracts with their addenda; school assignments assembled from several chapters. Instead of wrestling with desktop software or uploading sensitive paperwork to a random website, you can do it here in under a minute.

There is no catch. The tool is free for everyday use, the merged file carries no watermark, and nothing you drop in is ever transmitted anywhere. Your original files stay exactly as they were — the tool simply produces one new, combined PDF for you to download.
