HTML Obfuscator
Please be advised that obfuscation may cause false positives from poorly designed antivirus software. For example, it has come to our attention that any code obfuscated using the JavaScript method is detected as malicious by 4 out of 58 antivirus programs. This is beyond our control. We never add any malicious data to the code you provide.
What is HTML code obfuscation?
Generally, obfuscation is a set of transformations that preserve the code functionality while making the internals difficult to reverse-engineer. HTML code obfuscation is usually used for hiding some content from search engines, e-mail harvesting software, or unwanted eyes.
What is HTML Obfuscator used for?
This free tool can be useful if you want to hide some text in HTML. For example, it can help to protect your email addresses from spam by encoding mailto: links. It can also hide other personal data from parsing by automated web scraping programs.
What are the obfuscation methods?
Our online tool can obfuscate HTML using the following methods:
- Representing it as a JavaScript code. JavaScript must be enabled in the viewer's browser (most users already have it).
- Character entities, when every obfuscated character is defined by its numeric code. Pure HTML obfuscation method.
- You can also combine two previous methods, so the users with JavaScript enabled will be dealing with it, and others will use character entities.
Every obfuscation method adds its own code overhead: the most compact output is produced by the JavaScript method, code with character entities can be several times larger, and the third method is the most universal, but it produces the largest output. We encourage you to try all of them and choose the most appropriate one.
Is It Bullet Proof?
No. Please note that although this tool is able to hide information from simple e-mail harvesters and non-savvy users, it is not meant to be a solution with "unbreakable" protection, because every obfuscated code can be deobfuscated.
