❓ Frequently Asked Questions

Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. It's commonly used for data transmission and storage in text-based protocols like email and HTTP.

Use Base64 when you need to transmit binary data over text-based protocols, embed images in HTML/CSS, store binary data in JSON, or ensure data integrity during transmission. It's perfect for email attachments, API data, and configuration files.

No, Base64 is not encryption - it's just encoding. Anyone can decode Base64 strings easily. Don't use it for sensitive data protection. Base64 is for data format conversion, not security.

Yes, Base64 encoding increases the size by approximately 33%. Every 3 bytes of binary data becomes 4 characters in Base64. This is the trade-off for making binary data text-safe.

URL-safe Base64 replaces '+' with '-' and '/' with '_' to avoid conflicts in URLs and filenames. Regular Base64 uses '+' and '/' which can cause issues in web applications. Use URL-safe for data that will be transmitted in URLs.
