Combine several PDFs into one
Add two or more PDF files, drag them into the order you want, and merge them into a single document. The pages are joined in exactly the sequence you set. Everything runs in your browser — your files are never uploaded.
When merging helps
- Combine an offer, terms and an appendix into one contract.
- Bundle scanned receipts or invoices into a single file for accounting.
- Join chapters, hand-outs or report sections before printing or sharing.
How it works
Each source file is opened locally and its pages are copied, in order, into a new PDF — a lossless operation. Text, fonts and images are preserved, nothing is recompressed, and the result is assembled entirely on your device with an open-source library (pdf-lib).
Private and unlimited
Because the merge happens on your computer, there is no upload, no queue and no file-size paywall like on cloud services. Confidential documents never leave your device — you can even merge offline. On phones, keep the combined size moderate, since everything is held in the browser's memory.
Tip: need to drop or reorder individual pages first? Use the Organize PDF tool, then merge the cleaned-up files.
