About the Merge PDF
Drag in as many PDFs as you like, arrange the order, and merge them into a single document. Everything is processed locally with pdf-lib in your browser, so contracts, invoices and confidential reports never touch a server.
No page limits, no file-size limits, no signup and no watermark. The merged PDF preserves the original quality of every page.

Frequently asked questions
In what order are the files merged?
Top to bottom in the file list. Use the up/down arrows to rearrange before merging.
Does merging reduce quality?
No. Pages are copied byte-for-byte into the new document — the quality is identical to the originals.
My PDF is protected with a password. Will it work?
Password-protected (encrypted) PDFs usually cannot be merged. Remove the protection first, then try again.
