Chain this with other tools →NewHow it works
Base64 encoding converts binary data into ASCII text using 64 printable characters (A-Z, a-z, 0-9, +, /). This tool uses the browser's built-in btoa() and atob() functions for encoding and decoding, handling UTF-8 text properly through TextEncoder/TextDecoder.
Common Use Cases
- Encoding images or files for embedding in HTML/CSS data URIs
- Encoding authentication credentials for HTTP Basic Auth headers
- Decoding Base64 strings from APIs or configuration files
- Preparing data for systems that only accept ASCII input
Frequently Asked Questions
Why does Base64 make my data ~33% larger?
Base64 uses 4 characters to represent every 3 bytes of data, resulting in approximately 33% size increase. This is the trade-off for ASCII compatibility.
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode Base64 data. Never use Base64 alone to protect sensitive information.
