Does editing metadata change the content of my PDF?+
No — it only updates the document’s information (title, author, etc.). The pages and content stay exactly the same.
Is pdfcdf free to use?+
Yes. Every tool on pdfcdf is completely free, with no account, no watermarks, and no limits on how many files you process.
Are my files safe? Do they get uploaded?+
Your files never leave your device. Every tool runs entirely in your browser, so your documents are processed locally and are never uploaded to a server or seen by anyone.
Do I need to create an account or sign up?+
No. pdfcdf works instantly with no sign-up, no email, and no software to install — just open the tool and go.
Does it work on mobile phones and tablets?+
Yes. pdfcdf runs in any modern browser on phones, tablets, Mac, Windows and Linux — nothing to download.
