Is Base64 encryption?
No. It is an encoding that can be reversed by anyone with the value.
Tools
Base64 Encode / Decode
Encode and decode Unicode-safe Base64 text locally.
Encode UTF-8 text as standard Base64 or decode a standard Base64 text value in your browser.
How to use this tool
- Paste plain text to encode, or a Base64 value to decode.
- Select Encode or Decode.
- Review the output for the expected text or Base64 value.
- Copy the result into the system that expects it.
Ways to use it
- Inspect an encoded text value
- Decode a Base64 string received in a text-based field or API example.
- Prepare Unicode text
- Encode text that includes non-ASCII characters for a system expecting standard Base64 text.
Base64 converter notes
- This tool works with UTF-8 text values, not binary files or data URLs.
- It uses standard Base64. Base64url values need their URL-safe characters normalised before decoding.
- Base64 is an encoding, not encryption. Do not use it to protect sensitive information.
Common questions
Can I convert a file?
No. This page is for text input and output, not file or binary conversion.
Does it support Chinese and other Unicode text?
Yes. Text is encoded and decoded as UTF-8.
Why does decoding show an error?
The input may not be valid standard Base64. Check its characters and padding, or confirm whether it is Base64url.
