Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme representing binary data using 64 printable ASCII characters (A-Z, a-z, 0-9, +, /). Commonly used in URLs, JSON, and email.
What is URL-safe Base64?
URL-safe Base64 replaces + with - and / with _, and omits = padding. This makes it safe for URLs and filenames.
Is my data secure?
Yes — all encoding/decoding runs in your browser. No data is transmitted to any server.
Does Base64 encryption protect my data?
No. Base64 is encoding, not encryption. It's easily reversed. Don't use Base64 for security — use proper encryption instead.
