Five PDF tools that run entirely inside this page. Merge several files into one, pull a page range out of a long document, add or remove a password, or lay a smart card out as a printable booklet. The PDF is read into the tab's memory and stays there.

Why running in the browser matters more here than anywhere else
Which tool to reach for
Merge PDF joins files in the order you arrange them and keeps bookmarks intact. Split PDF extracts a page range, a single page, or every page as a separate file. Protect PDF adds an open password with AES-256 encryption. PDF Password Remover strips a password you already know from a file you own, which is the usual case when a bank sends a statement locked with your date of birth. Smart Card Booklet Maker arranges card-sized pages for duplex printing and folding.
What these tools cannot do
They cannot crack a password you do not have; removing protection requires the password. They do not perform OCR on scanned pages, and they do not edit text inside an existing PDF, because both need a rendering stack far heavier than a browser tab should carry. For those jobs a desktop application is the right answer.
Frequently asked questions
Are my PDFs uploaded anywhere?
No. Every operation runs in your browser using qpdf compiled to WebAssembly. The file is read into the page's memory and never sent to a server, logged, or stored. After the engine has loaded once, the tools keep working offline.
Is there a file size limit?
There is no imposed limit, but the file has to fit in your browser tab's memory alongside the result. In practice documents up to a few hundred megabytes are fine on a modern desktop; very large scans may be slower on a phone.
Can I remove a password I do not know?
No, and no honest tool can. Removing protection requires the password. These tools are for documents you own and can already open, such as a bank statement locked with your own date of birth.
