Base64Deco Editorial Team

Base64Deco is a Base64 encoder and decoder maintained by a small in-house group that also writes its articles — the same hands on the tool and on the page.

Articles here keep to Base64 Utilities rather than the site in general. The tool it documents converts text to and from Base64 with full UTF-8 support for Chinese characters and emoji, and auto-detects which direction you want, and the writing follows the same ground: embedding a data URI in a stylesheet, checking what a Base64 blob actually contains, encoding a token for an Authorization header.

Two checks happen before publication — does the method reproduce, and could the wording be mistaken for advice. Anything bordering on medical, financial or legal guidance is kept to the arithmetic, and the article says plainly when a professional is the right next step.

Errors and corrections go to support@base64deco.com. Once a mistake is confirmed it is corrected at source, on the page.
