Base64 Encoder for Text and Data
Encode text, JSON, or config values to Base64 for safe transport and storage.
Base64 Encoder
Encode plain text into Base64 so it can travel through systems that only accept ASCII-safe characters. Developers use this to package API payloads, headers, or config values without changing the underlying content.
How to use the Base64 Encoder
- Paste your text into the input.
- Click Encode.
- Copy the Base64 output.
Common use cases
- Embedding small strings inside JSON or XML.
- Creating Base64 values for headers or tokens.
- Preparing config values for transport or storage.
- Encoding samples for documentation or tests.
Tips & notes
- Base64 increases data size by roughly one third.
- This is an encoding format, not a security measure.
- Keep line breaks out of the input for clean output.

FAQ
What is Base64 encoding?
Base64 is a way to represent binary or text data using readable ASCII characters so it can be safely transmitted.

No. Base64 is not encryption and provides no security. Anyone can decode it.
Does this support UTF-8 or Unicode text?
Yes. UTF-8 and most Unicode characters are supported.
Do you store my input or output?
No. All encoding happens instantly and nothing is saved.
Why does the output end with = signs?
Padding characters (=) are part of the Base64 standard for alignment.
