What “pdfcdf” means
pdfcdf stands for Portable & Common Document Format. It’s our name for a simple idea: every document task you need — merging, splitting, editing, signing, converting — gathered into one calm, uncluttered place.
The world runs on documents: contracts, invoices, forms, scans, reports. pdfcdf is built to make working with those documents fast and effortless, without the ads, clutter and sign-up walls you find elsewhere.
Private by design
Every tool on pdfcdf runs entirely inside your browser. Your files are opened and processed on your own device and are never uploaded to a server. Nothing is stored, and no one — including us — ever sees your documents.
That’s not a setting you turn on; it’s how the whole product works. You can read the details on the security page.
Free, forever, for everyone
pdfcdf is free to use — no account, no watermarks, and no daily limits. It works on any modern browser, on phones, tablets and computers, with nothing to install.
