What is PDFFILZ?
PDFFILZ is a free toolkit for everyday PDF work: combining documents, pulling out a few pages, shrinking a file that is too big to email, converting photos into a PDF, and stamping or numbering pages before you send them on.
The difference from most online PDF sites is simple: your document never leaves your device. Everything happens inside this page, so a contract, a payslip or a medical scan stays exactly where it is.
How it works
Nothing is uploaded
There is no server that receives your documents. Files are opened, edited and saved by your own browser.
Real editing, not a preview
Pages are rebuilt with a full PDF engine, so merges, rotations and stamps are written into the real file.
Works without a connection
Once the page has loaded, every tool keeps working offline — handy on a plane or a bad hotel Wi-Fi.
Phone-first design
The same touch-friendly page grid runs on a phone, a tablet and a laptop, and installs as an app.

Free, with an optional Pro plan
Every tool is free to use each day. Pro removes the daily limit and the file size cap for people who work with documents all day long — it keeps the project running without ads or selling data, because there is no data to sell.
