Frequently Asked Questions

Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode Base64 instantly. Never use it to protect sensitive data.
Why does Base64 make text longer?
Base64 uses 64 characters to represent binary data, increasing size by about 33%. This is the trade-off for making binary data text-safe.
