FAQ
Is the OCR really private if it downloads a language file?
Yes. Only the OCR engine and English language model download once (like loading any library). Your actual document is read locally and never uploaded.
Which languages are supported?
OCR currently recognizes English. It works best on clear, printed text.
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.
