PDF Tools
Combine multiple PDF files into a single document in any order you choose. Drag and drop to rearrange your pages instantly.
Follow these simple steps to get instant, accurate results directly in your browser:
Click 'Choose Files' or drag and drop multiple PDF documents into the upload area.
Drag and drop the document cards or use the up/down arrows to order files in your preferred sequence.
Click 'Merge PDFs' to assemble the new document and download your unified file instantly.
The Merge PDF tool is a client-side document assembly utility that combines multiple independent PDF files into a single, unified document. Whether you are assembling multi-page legal briefs, collating monthly financial invoices, or organizing academic research portfolios, this tool binds pages in your exact designated order.
Built on low-level PDF document stream manipulation via pdf-lib, the merger parses the cross-reference tables (XRef), fonts, embedded images, and vector objects of each source PDF without flattening text or degrading graphical fidelity. It handles documents with disparate page orientations, non-standard page dimensions (such as Letter, A4, and Legal), and varied color profiles.
Because all document processing takes place directly in your browser's local memory via WebAssembly and JavaScript typed arrays, sensitive contracts, bank statements, and confidential records never touch an external cloud server, guaranteeing strict document privacy.
All document collation executes inside your browser memory without server transmission.
Easily reorder files visually before finalizing the merged PDF.
Retains crisp selectable text, embedded Type 1/TrueType fonts, and vector paths.
Seamlessly merges documents with differing page sizes (A4, Letter, A3, Legal).
Combine master service agreements, addenda, signed exhibits, and disclosures into one binder.
Merge multiple monthly vendor invoices and receipts into a single file for accounting audit.
Consolidate manuscript chapters, supplementary charts, and bibliographies for submission.
