Base64 Encoder / Decoder
Securely encode and decode text to Base64 format locally.
About Base64 Encoder / Decoder
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. Our Base64 tool is perfected for developers who need to encode sensitive configuration data, embed small images into HTML/CSS, or decode obfuscated strings in legacy code. It is completely client-side, making it the safest choice for processing credentials or private strings.
Key Features
- Fast encoding from plain text to Base64 format.
- Instant decoding from Base64 back to human-readable text.
- Support for special characters and UTF-8 strings.
- Visual validation of input to prevent decoding errors.
- Completely private: all processing is done in the browser.
How to use Base64 Encoder / Decoder?
- Choose either 'Encode' or 'Decode' mode using the primary switch.
- Paste your source text into the top input field.
- The transformation is triggered when you click the 'Process' button.
- Use the 'Copy' button on the result box to save the output.
FAQ
Is Base64 a form of encryption?
No. Base64 is an encoding scheme, not encryption. It can be easily decoded by anyone and should not be used alone to secure sensitive data without additional encryption (like AES).
What are common use cases for Base64?
Common uses include sending binary data over text-based protocols (like JSON/email), embedding small images directly into CSS/HTML via Data URIs, and simple obfuscation of configuration strings.
Does this tool support file uploads?
Currently, this tool is optimized for text-based encoding. For large binary files, we recommend using a specialized binary-to-base64 converter.
100% Privacy Guaranteed
All processing happens locally in your browser. We never see, store, or transmit your data. This tool is fully client-side and secure.
