About this tool
Base64 turns text into a set of safe characters so it can travel through systems that only handle plain text, such as URLs and data formats. It is an encoding, not encryption, so anyone can decode it. Never rely on it to protect secrets.
How to use Base64 Encode & Decode
- Type or paste your text or Base64 into the box.
- Select Encode or Decode.
- Copy the result.
Frequently asked questions
Is Base64 a form of encryption?
No. Anyone can decode it without a key, so do not use it to protect passwords or private data.
What does URL-safe Base64 mean?
It replaces the + and / characters and removes the = padding, so the result can be used safely in web addresses.
Why does decoding say my data is not text?
That Base64 holds a file or other binary data, which this tool does not show. It only decodes text at the moment.
