This PDF merge tool is built on the OpenDataLoader open-source local PDF parsing engine. All file processing is performed offline in your browser.
1. Local Batch PDF Parsing: Batch reads all pages, text, and image resources from all uploaded PDFs, loading all document data into browser local memory.
2. Drag-and-Drop Sorting Logic: Monitors file drag interactions, updates the order of all PDF files in real time, allowing free customization of the document stitching sequence.
3. Multi-Document Reassembly & Merge: Sequentially stitches every page of each PDF according to the user-defined file order, standardizing page sizes and layer structures into a single complete PDF data stream.
4. Local Merged PDF Export: After all documents are stitched and reassembled, a brand new merged PDF file is generated locally in the browser. One-click download without modifying any original PDF.
