# PDF Merger_ Combine multiple PDFs into one in your browser — no uploads, no server. Drag files to reorder, then merge and download. Your files never leave your device. **Drop PDFs here** or click to choose Select multiple files at once · processed locally · never uploaded ## How to use it Drop one or more PDFs onto the zone above (or click to browse — you can select multiple files at once). Each file shows its name, page count, and size. **Drag the handle** on the left of any row to reorder the files — the merged PDF follows that order exactly. Use the **↑ ↓** buttons on touch devices. Remove any file with **×**. Click *Merge* and pdf-lib copies every page from each source in order into a single new PDF, which downloads immediately. No page content is altered — fonts, images, and vector art are preserved exactly as they are in the originals.
