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.
Quick answer
A Base64 encoder converts readable text into Base64 and can decode Base64 back to text. ClickBuildLabs handles encoding and decoding in your browser, making it useful for debugging payloads, data strings, and simple web development tasks without uploading the text.
What is a Base64 Encoder?
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 do you use Base64 Encoder?
- 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.
What does Base64 Encoder help with?
Encoding a short text value
The text hello becomes aGVsbG8= when encoded as Base64. Decoding aGVsbG8= returns hello.
How does Base64 Encoder work?
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.
Base64 Encoder FAQ
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.
Does Base64 encoding happen in my browser?
Yes. Encoding and decoding run in your browser, so the text is not uploaded by this page.
Why does Base64 output sometimes end with equals signs?
Equals signs are padding characters. They help the encoded value fit the Base64 format and are normal at the end of many Base64 strings.
