Detailed Guide
Base64 encoding is a fundamental technique in web development and data transmission. It converts binary data into ASCII text format, making it safe to transmit over text-based protocols. This tool is essential for web developers working with data URIs, API developers handling binary data in JSON, and anyone needing to embed binary content in text formats. Remember that Base64 is not encryption - it's simply a different representation of the same data.
Frequently Asked Questions
Is Base64 secure?
No, Base64 is not encryption. It's an encoding scheme that can be easily decoded. Never use it for securing sensitive data.
Why use Base64?
Base64 is used to safely transmit binary data over systems designed for text, such as email or JSON APIs.
Can I encode files?
Yes, you can encode any file type including images, PDFs, and documents. The tool handles binary data correctly.
