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.
