Frequently asked questions

Is Base64 encryption?

No — it is an encoding anyone can reverse. Don’t use it to protect secrets.

Are my files uploaded to a server?

No. Everything happens inside your browser using your own device. Files are never uploaded, stored or seen by anyone — you can even switch off the internet after the page loads and the tool keeps working.
