What this tool does
Base64 represents arbitrary data using 64 printable characters, which makes it safe to embed in URLs, JSON, email and data URIs. This converter encodes through UTF-8 first, so accented letters, emoji and CJK characters survive the round trip instead of turning into question marks.
How to use it
- Paste the text or Base64 string you want to convert.
- Press Encode to produce Base64, or Decode to read it back.
- Copy the result.
Privacy

Frequently asked questions
- Does Base64 encrypt my data?
- No. Base64 is an encoding, not encryption — anyone can decode it. Use it for transport, not for secrets.
- Why did decoding fail?
- The input must contain only Base64 characters and correct padding. Stray spaces, line breaks or truncated strings will fail.
