All processing happens locallyWhat this tool does
Text Encrypt & Decrypt is a local text encryption tool, the calculation runs entirely in your browser and nothing is uploaded.
Useful for briefly turning text into an unreadable blob to share, such as a temporary password or meeting notes. Note this is lightweight obfuscation and not suitable for high-value secrets.
How to use it
- Paste or type your content into the input field at the top, or press the sample button to load demo data.
- Adjust the options below the input, such as output format, separators, letter case or precision.
- Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
- When the result looks right, use the copy button in the corner, or download it as a local file.
Tips and notes
Clean up stray spaces and line breaks before pasting for more accurate results.
