About this tool
Merge PDF is a free online tool. Combine multiple PDF files into one document.
After uploading multiple PDF files, the tool displays the contents of each file as a thumbnail. You can drag and drop to adjust the order of files, or preview the page of each file. After confirming the order, click Merge, and the tool will splice all pages into one PDF download in order. Support batch uploads and process dozens of files at a time.
PDF merging is done on the browser side using the pdf-lib library. The library parses the object structure of each PDF file, extracts page content (including fonts, pictures, comments), and then reorganizes it into a new PDF file. Do not upload any data to the server to ensure privacy and security.
Suitable for consolidating scattered documents into a single report, contract, e-book, etc. It is safer than online merge services, and sensitive documents will not leave local.
