Frequently asked questions
No. The merge runs entirely in your browser: each PDF is read into memory, the pages are copied into a new document, and the result is saved on your own device. Your files are never sent anywhere — that is the difference from most online PDF mergers.
Each file you add appears in a numbered list and is merged top to bottom. Use the up and down buttons next to a file to move it, or remove a file with the Remove button. The order in the list is the order of pages in the final PDF.
There is no fixed limit, but because everything runs in your browser the practical ceiling is your device's memory. Merging a handful of typical documents is instant; very large files (hundreds of megabytes) may be slow or run out of memory on low-end devices.
It can open PDFs that are flagged as encrypted but not actually locked, but it cannot merge a PDF that requires a password to open. Remove the password in your PDF viewer first, then merge the unlocked copies.
