Base64 Encoder and Decoder
Encode or decode Base64 text with UTF-8 support. Free Base64 tool; not encryption.
Convert UTF-8 text to Base64 or decode payloads. Base64 is an encoding scheme, not encryption—anyone can decode it.
Text is processed locally; nothing is stored on servers.
Use cases
- Decode JWT payload segments for debugging (always verify signatures separately).
- Encode small configuration blobs for test fixtures.
- Inspect Base64 in API examples during integration work.
Frequently asked questions
Is Base64 secure?
No. It provides no confidentiality. Use proper encryption and secret management for sensitive data.
Does it support files?
This version focuses on text. Paste text content rather than binary files.
Why does decoding fail?
Check for invalid characters, missing padding, or non-UTF-8 binary data pasted as text.
