Frequently Asked Questions

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data using a set of 64 characters. It's commonly used to transmit data over media designed to handle text, ensuring safe data transfer across different systems.

Why use URL-safe Base64?

URL-safe Base64 replaces characters that have special meaning in URLs (+ and /) with safe alternatives (- and _). This makes the encoded data safe to use in URLs, filenames, and other contexts where certain characters might cause issues.

How does UTF-8 encoding help?

UTF-8 encoding ensures proper handling of international characters and special symbols in your JSON data. It preserves the exact character representation when converting to Base64, preventing data corruption or encoding issues.

Is my data secure?

All conversion happens directly in your browser. No data is sent to any server or stored anywhere, ensuring your information remains private and secure. Note that Base64 encoding is not encryption - it's an encoding scheme designed for data transfer.
