Files stay on your device

How we protect your files

Last updated: 9 November 2026

When you use most online PDF tools, your file travels to a company's server, gets processed there, and comes back. Dekiko works differently: your file never leaves your device.

How it works

  1. When you open a tool, your browser downloads the Dekiko page and the code for that tool.
  2. When you choose a file, your browser reads it from your phone or computer into its own memory.
  3. The tool's code changes the file right there, inside your browser tab.
  4. You download the result straight from that memory. Nothing is sent back to us.
  5. When you close or reload the tab, the browser clears the files from memory.

What this means for you

  • We never receive, store or see your documents, so they cannot leak from our side.
  • There is no upload wait, which makes big files faster on slow connections.
  • Sensitive papers such as Aadhaar, PAN, passports, marksheets, bank statements and contracts are safe to use.

Check it yourself

You do not have to take our word for it.

  • Go offline. Open a tool and add your file. Then turn off Wi-Fi and mobile data, and press the button to run the tool. It still works, because nothing needs to be sent anywhere.
  • Watch the network. On a computer, open your browser's developer tools (F12), go to the Network tab, and use a tool. You will see no request carrying your file.

How we protect the website

  • The whole site is served only over HTTPS.
  • A strict content security policy lets the page load code only from dekiko.com, which blocks injected scripts.
  • We do not use accounts or passwords, so there is no login data to steal.
