About Base64 Encoding
This tool helps you convert between raw text and Base64 when working with systems that accept text-only payloads. It is useful for debugging API requests, reading token segments, and handling data URLs without leaving your browser.
Common use cases
- Preparing binary-like content for JSON or form payloads
- Decoding Base64 segments while debugging auth tokens
- Converting inline assets for data URL usage
FAQ
- What is Base64 encoding used for?
- Base64 encoding represents binary or text data as ASCII characters so it can be transported in text-only formats. Common examples include JSON payloads, email bodies, and data URLs.
- Is Base64 safe for passwords or secrets?
- No, Base64 does not secure data because anyone can decode it. Use encryption and proper secret handling when you need confidentiality.
- Why does Base64 output end with '=' characters?
- The '=' symbols are padding used to keep encoded output aligned to a multiple of four characters. Some Base64URL implementations omit padding, so output may differ by context.
- Can I encode and decode Unicode text or emoji with Base64?
- Yes, as long as the text is handled as UTF-8 end to end. Mismatched character encodings across systems can produce unreadable decoded output.
