Base64 Encoder
Encode text to Base64 and decode Base64 back to text. Client-side processing, no data sent to servers. Toggle between encode and decode modes.
About this tool
Use this Base64 tool to encode plain text into Base64 or decode Base64 back into readable text. It is useful for data URLs, simple payloads, and debugging encoded strings.
How to use
- Choose whether you want to encode text or decode Base64.
- Paste your text or Base64 string into the input area.
- Review the output and copy it when it matches what you need.
Example
Encoding a short text value
The text hello becomes aGVsbG8= when encoded as Base64. Decoding aGVsbG8= returns hello.
How it works
What Base64 does
Base64 represents text or binary data using a limited set of safe characters. It is an encoding format, not encryption, so it should not be used to hide secrets or protect sensitive data.
Frequently Asked Questions
Is Base64 encryption?
No. Base64 is only an encoding method. Anyone can decode it back to the original text if they have the encoded value.
What kind of input can I encode?
This tool is intended for text input. For image files, use the Image to Base64 tool instead.
Is my text uploaded?
No. Encoding and decoding happen in your browser.
