Frequently Asked Questions
What is text steganography?
Text steganography is the art and science of hiding secret messages within ordinary text using invisible Unicode characters. Unlike encryption which scrambles text, steganography conceals the very existence of the hidden message, making it appear as normal text to casual observers.
How does zero-width character steganography work?
Zero-width characters are invisible Unicode characters that don't display visually but exist in the text data. Our tool strategically inserts these characters between words and letters in specific patterns that encode your secret message. The text looks completely normal but contains hidden information.
Is this text steganography tool free to use?
Yes, our text steganography tool is completely free to use with no registration required, no usage limits, and no hidden fees. You can hide unlimited secret messages in your text and extract hidden messages from any steganographic text.
Is my hidden text secure and private?
Absolutely. All steganography operations are performed locally in your browser using JavaScript. No text data, secret messages, or carrier text is transmitted to our servers, ensuring complete privacy and security of your sensitive information.
Can the hidden text be detected by others?
The hidden text is virtually undetectable to casual observation and most text processing systems. However, specialized steganography detection tools can identify the presence of hidden characters. For maximum security, combine with encryption before hiding.
What types of text can I use as carriers?
You can use any text as a carrier including emails, documents, articles, social media posts, and more. The carrier text should be reasonably long to accommodate your secret message. Longer carrier texts provide better concealment capacity.
How much text can I hide in a carrier message?
The hiding capacity depends on the length of your carrier text and the steganography method used. Generally, you can hide approximately 1 character of secret text per 8-10 characters of carrier text using zero-width character methods.
Will the hidden text survive copy and paste operations?
In most cases, yes. Zero-width characters typically survive standard copy-paste operations, email transmission, and document transfers. However, some text processing systems may strip invisible characters, so always test your specific use case.
