Frequently Asked Questions
Can I convert an HTML file to Base64?
Yes. Upload an HTML or HTM file and encode its contents directly in your browser.
Can I create an unreadable HTML file?
Yes. HTML → Obfuscated creates a standalone HTML file where the original source is stored as Base64 and decoded when the file opens.
Is Base64 encryption?
No. Base64 is encoding, not encryption. The original source can still be recovered by decoding the Base64 data.
Can the obfuscated HTML still run JavaScript?
Yes. The generated wrapper decodes the original HTML in the browser and writes it into the document.
Does FixImageFormat upload my HTML?
No. Encoding, decoding, and obfuscation happen locally in your browser.
