Base64 Encode Decode
Encode text to Base64 or decode Base64 back to plain text in one browser tool. Useful for API debugging, token inspection, and encoded config values.
Tool Interface
Functional explanation
Encodes plain text to Base64 and decodes Base64 back to readable text.
- Prepare transport-safe text fragments.
- Inspect Base64 strings from logs and APIs.
- Check whether source text is valid Base64 input.
How to use
Convert plain text to Base64 and decode Base64 back into readable text instantly. This page is useful for API debugging, token inspection, encoded configuration checks, and quick transport-safe conversions.
- Choose Encode to convert plain text into Base64 or Decode to restore the original text.
- Paste the source text or Base64 value into the input area.
- Run the conversion and review the output.
- Copy the result into your API request, config file, or debug notes.
Example
Input
hello-123
Output
aGVsbG8tMTIz
Encoding is reversible and not encryption.
Common mistakes
- Treating Base64 as data protection.
- Mixing URL-safe and standard Base64 alphabets.
Output interpretation tips
- Decode failures often indicate invalid alphabet or padding.
- Binary payloads should be interpreted as bytes, not always UTF-8 text.
Security and privacy notes
- Do not store secrets as plain Base64 and assume security.
- Use encryption when confidentiality is required.
