Why Merge PDFs?
Merging PDF files is one of the most frequent document tasks in modern workflows: combining chapters into a complete report, assembling contract addenda into a single file, merging bank statements for expense reporting, or packaging multiple form submissions into one document for a records system. A single merged PDF is easier to email, archive, print, and review than a collection of individual files.
Reorder Before Merging
Drag any PDF up or down to set the final page order before generating the merged file. Each card shows the filename, page count, and file size so you can confirm everything is in order. The merge produces a standard PDF file readable by Adobe Acrobat, Preview, every browser, and every mobile PDF viewer — with all original formatting, fonts, images, and bookmarks preserved.
Completely Private
PDF merging happens entirely in your browser using pdf-lib, an open-source JavaScript library. No file is ever uploaded to a server — not even temporarily. Your PDFs could contain legal contracts, medical records, financial statements, or anything else sensitive, and they will never leave your device. This is the fundamental privacy advantage of browser-based document processing over cloud-based alternatives.
