Our free online PDF merger makes combining documents fast and simple. Follow these steps:
PDF merging (also called PDF combining or joining) is the process of taking two or more separate PDF files and combining them into a single unified document. This is useful when you have:
Instead of emailing multiple attachments or printing and re-scanning, a PDF merger creates one clean, organized file in seconds.
Many online PDF tools upload your documents to remote servers, which raises legitimate privacy concerns — especially for sensitive files like contracts, medical records, or financial documents. EverydayTools Merge PDF is different: it uses the open-source pdf-lib library to process everything directly in your browser.
There are no file queues, no waiting for server responses, and no risk of your documents being stored or misused. The result is a faster, safer merging experience that works even without a stable internet connection once the page has loaded.
Your privacy is our top priority. This tool operates on a zero-upload model: your PDF files are read directly by your browser's JavaScript engine and are never transmitted to any server. Once you close the tab, all data is discarded. We collect only standard anonymous analytics (page views, device type) via Google Analytics, as described in our Privacy Policy.
EverydayTools Merge PDF works on any modern device and browser:
Upload your PDFs using the drag-and-drop area or the file picker, arrange them in order, then click Merge & Download. Your combined PDF is ready in seconds.
