What is Base64 encoding?

Base64 encodes binary data as ASCII text using 64 characters. It is commonly used for embedding images in HTML, storing data in JSON, and sending binary content over text-based protocols.

When do I need URL encoding?

URL encoding converts special characters (spaces, ampersands, etc.) into percent-encoded form so they can appear safely in URLs. Use it when building query strings or handling user input in URLs.

Are these tools secure?

All encoding runs in your browser. Your data is not sent to our servers. Note: encoding is not encryption; Base64 and similar schemes can be decoded by anyone.
