Encoding Tools
3 free encoding tools, all running privately in your browser.
These free encoding tools convert data to and from Base64, URL encoding, and HTML entities. They're essential for safely moving binary data and special characters through text-based systems like JSON, URLs, and HTML - and every conversion happens locally in your browser.
Encoding is not encryption: Base64 and URL encoding make data safe to transport, but they hide nothing and anyone can reverse them. Understanding that distinction prevents a common security mistake. Our blog post on Base64 covers exactly what each encoding is for and when not to use it.
Base64 Encoder
Encode text to Base64 instantly.
Base64 Decoder
Decode Base64 back to plain text.
URL Encoder / Decoder
Encode or decode URL components.
Frequently asked questions
Is Base64 a form of encryption?
No. Base64 is encoding, not encryption - it's instantly reversible by anyone and provides zero secrecy. Its purpose is safely transporting binary data through text-only systems, not protecting it.
