❓ Frequently Asked Questions
What does this tool do?
Base64 is a text encoding method that converts binary or plain text data into a limited ASCII character set. It is commonly used in APIs, email payloads, tokens, and debugging workflows.
What advanced options does it support?
You can switch between normal Base64 and URL-safe Base64, strip line breaks automatically, swap input/output, and load a sample to test the workflow quickly.
