How to use it
- Choose encode or decode.
- Paste your text or Base64 string.
- Copy the result.
Frequently asked questions
- Is Base64 encryption?
- No. It is an encoding that anyone can reverse, so never use it to hide secrets.
- What is URL-safe Base64?
- A variant that replaces + and / with - and _ and drops padding so it can sit inside URLs.
