Frequently asked questions
What is Base64?
Base64 represents binary data with 64 printable characters so it can travel through systems that only handle text โ for example in emails, data URLs or JSON.
Is Base64 encryption?
No. Anyone can decode Base64. Never use it to protect passwords or secrets.
When do I need URL encoding?
When text with spaces or special characters (like & ? = # or umlauts) must go into a URL or query parameter.
