About This Tool
PDF Merger combines multiple PDF files into one document. Upload as many PDFs as needed, drag them into the right order, then merge. Every page from every file is preserved in sequence.
PDF.js renders each page to a canvas for stitching, and jsPDF reassembles them into a single output PDF. Page dimensions are preserved per page. Documents with mixed paper sizes are handled correctly.
Nothing is uploaded. All merging happens in your browser, keeping your documents private. Useful for combining chapters, reports, invoices, or scanned pages into one file.
