Frequently asked questions
Are my files really not uploaded?
Right. Everything happens inside your browser. Open the Network tab in your browser's developer tools while you work, and you'll see that no file is sent.
How many files, or how many MB, can I merge?
There's no fixed limit. You can merge as much as your device's memory allows, usually enough for hundreds of pages.
Does it work with password-protected PDFs?
Password-protected PDFs can't be opened. Open the file in a PDF viewer with the password, save a copy without it (for example with "Print → Save as PDF"), and use that copy.
Can I merge pages of different sizes?
Yes. Each page keeps its original size. Mixing A4, Letter and other sizes in one PDF is perfectly normal.
