Base64 Encode / Decode
Description
Base64 is a ubiquitous encoding scheme used to represent binary data in an ASCII string format. It's essential for transmitting data over media that are designed to deal with text, such as embedding images directly into HTML or sending data via JSON APIs. The Base64 Converter allows you to instantly encode text into Base64 strings or decode them back into readable content. This tool is UTF-8 aware, meaning it correctly handles special characters, emojis, and non-Latin scripts that often break older converters.
What It Does
Encodes text to Base64 format and decodes Base64 strings back to text.
How To Use
- Select Mode: Choose "Encode" to creating Base64, or "Decode" to read it.
- Input: Type or paste your content in the Input box.
- Result: The output appears instantly. Use the Copy button to grab it.
Who It Is For
Web developers, network engineers, and anyone debugging API responses or headers.
Freqently Asked Questions
Is Base64 encryption?
No. Base64 is an encoding, not encryption. It obfuscates data but provides no security. Anyone can decode it.
Why does the output increase in size?
Base64 represents 3 bytes of binary data with 4 ASCII characters, resulting in a roughly 33% increase in size compared to the original data.
Can I convert images here?
This specific tool is optimized for text strings. For images, look for our Image to Base64 tool (coming soon).
