Frequently asked questions
What is text obfuscation?
Text obfuscation is the process of altering plain text to make it difficult for automated scrapers or casual viewers to read while retaining its underlying content or making it restorable.
Is text obfuscation the same as encryption?
No. Obfuscation simply hides or disguises text to confuse basic scrapers and filters, whereas encryption uses cryptographic keys to mathematically secure data against unauthorized decryption.
Can obfuscated text be deobfuscated?
Yes, if the obfuscation technique is deterministic, such as character mapping or reversible Unicode encoding, the process can be reversed to restore the original plain text.
Does this text obfuscator store my data?
No. The tool runs completely within your web browser via client-side JavaScript, meaning none of your text is sent to or stored on any server.
Is this tool free to use?
Yes, the text obfuscator is free to use with no limits and does not require an account or subscription.
