Why your files stay private here
Most online file tools upload your documents to a server, process them there, and send the result back. OneCodeTools works differently: every tool runs inside your web browser, on your own computer or phone. Your PDFs, photos, videos, and QR codes are never sent anywhere.
That means there is nothing to sign up for, no waiting for uploads, and no copies of your files sitting on someone else's computer. The site's security settings even stop its pages from sending data to other websites. Read the privacy policy.
