Question 1

What is Base64 encoding?

Accepted Answer

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data for email attachments, embedding images in HTML/CSS, and transmitting data over text-based protocols.

Question 2

How do I use this Base64 tool?

Accepted Answer

Simply enter your text in the input field and select whether you want to encode or decode. The conversion happens instantly. You can also enable URL-safe encoding or line wrapping for specific use cases.

Question 3

What is URL-safe Base64 encoding?

Accepted Answer

URL-safe Base64 replaces the characters + and / with - and _ respectively, making the encoded string safe to use in URLs and filenames without requiring additional URL encoding.

Question 4

Why would I need line wrapping?

Accepted Answer

Line wrapping breaks long Base64 strings into shorter lines (typically 76 characters) which is required by some email standards (like MIME) and makes long encoded strings more readable.
