Base64 Encoder
Encode text to Base64 or decode Base64 strings back to readable text.
What Is Base64 Encoding and When Should You Use It?
Use this Base64 encoder and decoder when you need to inspect tokens, test API payloads, work with data URIs, or convert plain text into a Base64 string. Switch between encode and decode modes, paste your input, and copy the result without leaving the page. Base64 is useful for representing binary or special-character data in text-only systems, but it is not encryption. Anyone can decode it, so do not treat Base64 as a way to hide secrets.
Core Features
Encode plain text into Base64
Decode Base64 back to readable text
Local browser processing with copy-ready output
Common Use Cases
Inspect encoded API values
Decode Base64 strings from headers, tokens, logs, or test payloads to understand what a system is actually sending or receiving.
Prepare text for text-only channels
Encode content when a system expects Base64, such as examples, simple data URIs, email-related workflows, or integration tests.
Explain encoding during debugging
Show teammates that Base64 changes representation but does not encrypt data, which helps avoid treating encoded values as secrets.
How to Encode and Decode Base64 in 5 Steps
- 1
Choose Encode if you want to convert readable text into Base64.
- 2
Choose Decode if you want to turn a Base64 string back into readable text.
- 3
Paste or type your input into the editor.
- 4
Review the generated output and check for invalid Base64 errors when decoding.
- 5
Copy the result, or clear the input to start a new conversion.
Base64 Encoder FAQs: Common Questions Answered
No. Base64 is encoding, not encryption. It changes how data is represented, but it does not protect the data from being read.
