  • Runs locally in your browser for privacy.
  • Useful for test payloads and simple data transport tasks.

When to Use Base64 Encode

  • Prepare sample payloads for API testing.
  • Encode basic auth values before constructing headers.
  • Convert snippets for demos, docs, or debugging.

Decision Guide

Best for

  • Small text payloads and quick developer workflows.
  • Ad-hoc encoding during testing and debugging.

Avoid when

  • You need encryption (Base64 is only encoding, not security).
  • You are handling secrets in untrusted browser sessions.

Example

Encode a simple string

Input

hello@rohansurve.in

Output

aGVsbG9Acm9oYW5zdXJ2ZS5pbg==

Base64 changes representation only. Decode returns the original text.

Troubleshooting

Output seems different across systems.

Check text encoding. This tool uses UTF-8 and handles Unicode input correctly.

Expected encrypted output but got readable pattern.

Base64 is not encryption. Use a cryptographic method if confidentiality is required.

FAQs

Is Base64 secure?

No. It is an encoding format, not encryption. Anyone can decode it easily.

Does this tool upload my input?

No. The conversion runs in your browser and does not send data to servers.
