Merging without a server
Most online PDF mergers upload your documents to their servers. This tool merges them in your browser using the pdf-lib library, so bank statements, contracts and ID proofs never leave your device. Add the files in the order you want them to appear and click Merge.
Tips
Password-protected PDFs must be unlocked first. Very large scanned PDFs merge fine but take a few seconds. To merge only certain pages from a file, split it first with the Split PDF tool.
