Frequently Asked Questions
What is Base64 encoding?
Base64 is an encoding scheme that converts binary data into ASCII characters. It's commonly used to transmit binary data over text-based protocols, embed images in HTML/CSS, or safely include binary data in JSON. It increases the data size by approximately 33% but ensures compatibility with text-only systems.
Why use URL encoding?
URL encoding converts characters that are not allowed in URLs into a format that can be transmitted over the Internet. This ensures that special characters, spaces, and Unicode characters can be properly used in web addresses and query parameters without breaking the URL structure.
The difference between encoding and encryption
Encoding is a reversible transformation of data format that doesn't require a key and is designed for compatibility, not security. Encryption, on the other hand, is a security measure that transforms data using algorithms and keys to make it unreadable without proper decryption. Encoding tools like Base64 provide no security protection.
Is my data secure when using these tools?
Yes, all encoding operations are performed entirely in your browser. Your data never leaves your device or gets sent to any server. For sensitive data, you can even use these tools offline once the page is loaded.
