Base64 Encode and Decode Guide
Base64 is commonly used to represent text or binary data in a safe plain-text format. Developers use it in API examples, email templates, small embedded assets, tokens, and configuration workflows.
Base64 is not encryption. Anyone can decode it. Do not use Base64 to hide passwords, private keys, or sensitive customer data. Treat it as a data conversion format, not a security feature.
Best use cases
- Encode text for API testing
- Decode sample payloads while debugging
- Prepare small strings for config examples
- Understand encoded webhook data
Pro tips
- Never treat Base64 as secure encryption
- Check character encoding before sharing
- Avoid very large Base64 blobs in pages
- Remove secrets before decoding online
