Check the processing label
Each tool page states whether processing occurs in your browser or uses a network connection.
Browser processing keeps the selected input on your device during the transformation.
- Use browser tools for private text and files when they meet your task.
- Review the stated network reason before you use a network tool.
Understand the limits
A browser tool still uses memory and temporary object URLs while its page remains open.
Base64, URL encoding, and formatting change data representation. They do not encrypt the data.
Finish the task safely
Check the result before you download, copy, or share it.
Close the page when you finish processing sensitive data on a shared device.
