About Merge PDF

Combine PDF files into a single document without uploading anything. Add as many PDFs as you need, drag them into the order you want, and we join them into one file with pdf-lib while preserving the original page quality — ideal for stitching together reports, scans, and contracts.

The merge happens entirely in your browser with no upload and no signup, and it works offline. Your documents stay on your device, which matters when they're confidential.
