Merge PDF
Combine multiple PDF files into a single document, in the order you add them - use the up/down arrows next to each file to reorder them before merging, and the final PDF follows that order exactly. Merging runs entirely in your browser using pdf-lib, so your files are never uploaded to a server. There's no hard limit on how many PDFs you can combine at once; it's bounded only by your device's own memory, and a handful of typical documents merges instantly.
Drag & drop files, or click to browse
Add two or more PDFs - they'll be combined in the order added
