Q: Is my data secure when using Base64 Encoder?
Yes. All encoding is performed entirely in your browser using client-side JavaScript. Your data never leaves your device and is not sent to any external server, ensuring complete privacy and security.
Q: What character encoding is used for Base64 encoding?
The encoder uses UTF-8 character encoding by default, which supports all Unicode characters including international text, emojis, and special symbols. This ensures your encoded data can be decoded back to the original content accurately.
Q: Can I encode binary files like images with this tool?
This tool is designed for encoding text strings to Base64. For binary file encoding, the input text is treated as a UTF-8 string. If you need to encode raw binary data, consider using file-specific encoding tools.
Q: What is the difference between standard Base64 and URL-safe Base64?
Standard Base64 uses + and / characters which can cause issues in URLs. URL-safe Base64 replaces these with - and _ respectively, making the encoded string safe to include in URLs and query parameters.
Q: Is there a size limit for encoding?
Since all processing happens in your browser, the practical limit depends on your device's available memory. Most modern browsers can handle several megabytes of text without issues, but very large inputs may slow down the encoding process.
